Gefahr

Einleitung

Wenn dein iMac mit einer SSD oder Fusion Drive konfiguriert wurde, enthält es eine Blade SSD auf der Rückseite des Logic Boards. Nutze diese Anleitung, um die Blade SSD auszubauen und zu ersetzen.

Bevor du mit jeglicher Arbeit an deinem iMac anfängst: Ziehe den Netzstecker und betätige den Netzschalter zehn Sekunden lang, um die Kondensatoren der Stromversorgung zu entladen.

Achte darauf, die Kondensatorleitungen oder freiliegende Lötverbindungen auf der Rückseite der Stromversorgung nicht zu berühren.

Beginne an der linken Seite des Bildschirms, auf der Seite der Ein-/Aus-Taste, und schiebe das iMac Opening Tool zwischen Bildschirm und Gehäuse.
  • Beginne an der linken Seite des Bildschirms, auf der Seite der Ein-/Aus-Taste, und schiebe das iMac Opening Tool zwischen Bildschirm und Gehäuse.

  • Das iMac Opening Tool verhindert, dass es zu tief in das Gerät gesteckt wird. Solltest du jedoch ein anderes Werkzeug benutzen, stelle sicher, dass du es nicht weiter als 9,5 mm in den iMac steckst. Es besteht sonst die Gefahr, Antennenkabel oder andere Komponenten zu beschädigen.

Would a heat gun make this step easier? Or damage the iMac?

Clark Green - Antwort

A heat gun wouldn’t help you here as you still need to cut though the adhesive. You also risk damaging the display with the excessive heat.

Dan -

Removing the original adhesive is easier than removing newly applied adhesive (e.g., if you have to reopen iMac).  If you should happen to need to reopen the iMac, please use extreme caution and highly consider my suggestions below.

When using the pizza cutter tool, do the first few steps in reverse starting with step 8.  Starting on the left side is better since this is where the adhesive is narrowest.  The right side has two antennas and the top right has one, see the pictures for step 18-21, they are the brass colored metal rectangles near the edges.  The adhesive on these pieces are wider and therefore have more holding power.  The thickness of the pizza cutter tool is enough to crack the glass.

Walter Hayden - Antwort

Continuing from my previous comment.  To remove the adhesive on the right side you’ll need to create a very slight gap to give the pizza cutter some more room.  Do this by cutting the adhesive on the left side up and around to the camera.  Before attempting to cut the right side. Carefully slide the plastic cards (I purchased two sets) to ensure the adhesive on the left top and side is completely free.  Now slowly move towards the right side.  After every inch or two of removing new adhesive, slide the card over to create this slight gap.  Be careful to not move the card too close to where the adhesive has not been cut.  You want to create a very slight gap without creating too much pressure.  Use extra caution with approaching the areas where the antenna are since the adhesive is stronger here and will need some additional cutting.  Follow this approach all the way around the right side.  Be careful to not create too much pressure at any one time.  Good Luck!.

Walter Hayden - Antwort

I would highly, highly, highly recommend AGAINST doing this at home. I followed these instructions to a T, and still somehow managed to have the screen not be able to turn on after the hard drive replacement. Then, once you’ve opened your Mac yourself, Apple will refuse to fix anything on the computer, and even other third party, Apple-authorized repair facility will refuse to repair it for you, and you will have to locate a non-authorized Apple repair facility. There, I am having to pay ~$600 to fix things that got screwed up, even though I followed the instructions here to a T, step by step, and did everything slowly and methodically.

Beware, if you’ve never done this before, that be locked out of ever being able to use an Apple repair facility, or Apple-authorized repair facility, if you mess things up here now.

Luke Gibson - Antwort

I performed this on a Late 2015 iMac and there weren’t any significant differences to these steps, but I did find the repair to be nerve-wracking. My model cost nearly $3,000 and about 10 steps into this guide (which I did fully read ahead of time) I was thinking, “what have I got myself into?” But I didn’t rush and happily I’m typing this on my repaired iMac! I found a video from OWC that was more useful than the photos in this guide for certain steps: https://vimeo.com/139364064

Benutze das Werkzeug wie einen Pizzaschneider - rolle es entlang des Schlitzes zwischen Bildschirm und Gehäuse und es wird den Kleber durchschneiden.
  • Benutze das Werkzeug wie einen Pizzaschneider - rolle es entlang des Schlitzes zwischen Bildschirm und Gehäuse und es wird den Kleber durchschneiden.

  • Stelle sicher, dass du den Griff immer hinter dem Rad hinterher schiebst. Ansonsten könnte das Rad aus dem Griff herausrutschen.

  • Fahre mit dem Werkzeug entlang der linken Gehäuseseite.

I found the 'pizza cutter' surprisingly smooth at cutting through four-year-old adhesive.

Gerry - Antwort

  • Fahre mit dem Werkzeug um die obere linke Ecke.

Kommentar hinzufügen

  • Schneide den Kleber entlang der oberen linken Gehäuseseite durch.

The pizza cutter will sink in all the way to the tool handle when the adhesive is full cut, but don’t feel you have to do this in one motion. Some parts cut easier and some require a lot (like 20x) of gentle back and forth.

Anthony Zimmerman - Antwort

  • Zerschneide den Kleber weiter entlang der oberen Gehäuseseite.

  • Du solltest mit dem Gerät immer etwas vor- und zurückrollen durch den Teil, den du bereits durchgeschnitten hast, um so viel wie möglich von dem Kleber zu lösen.

  • Fahre mit dem Werkzeug entlang der rechten Gehäuseseite abwärts.

Kommentar hinzufügen

  • Schneide den Rest des Klebers an der rechten Seite des Gehäuses bis ganz nach unten durch.

  • Jetzt solltest du das Werkzeug noch einmal zurück um das Gerät schieben, um so viel wie möglich von dem Kleber zu lösen.

Kommentar hinzufügen

  • Das Opening Tool hat schon den größten Teil der Arbeit erledigt, jedoch klebt der Bildschirm immer noch etwas am Gehäuse. Eine Plastikkarte ist nötig, um noch den letzten Rest an Kleber zu lösen.

  • Lege den iMac mit dem Bildschirm nach oben auf einen Tisch.

  • Beginne an der oberen rechten Seite des iMacs und schiebe eine Plastikkarte zwischen Bildschirm und Gehäuse.

    • Sei vorsichtig und stelle sicher, dass du die Karten nicht weiter als 9,5 mm in den iMac steckst. Es besteht sonst die Gefahr, Antennenkabel oder andere Komponenten zu beschädigen.

I actually DESTROYED my display (black vertical strips) by pushing the card in a bit TOO DEEP. So it is REALLY important to insert the card only a bit (1-2mm) more than the cutter wheel, in particular at the top side, where many flat cables connect the panel with the PCB. These can be damaged very easily!

Peter Fischer - Antwort

Same thing with me…. Pushed cards to far…. new panel needed…€600…..

i think ifixit needs to place a bigger caveat, as I have missed it the first time

Edgar Broekema - Antwort

i successfully upgraded two imacs. one opened with ifixit pizza knife and another with a regular paper knife. however, when i had to open the first one once again i broke its screen glass. it seems ifixit adhesive strips are too strong. next time i’ll try to use heater to weaken glue tension.

Eugene Kharkov - Antwort

  • Drehe die Plastikkarte leicht, um den Abstand zwischen Bildschirm und Gehäuse zu vergrößern.

  • Bewege die Karte vorsichtig und beanspruche das Bildschirmglas nicht übermäßig. Eine Lücke von etwa 6 mm ist ausreichend.

My children tend to collect cards like this from hotels, Disneyland, old IDs, iTunes cards, gift cards etc. They came in handy for this step. After wedging in the first card into the left corner, I wedged the left corner, then added cards along the bottom edge. Finally I continued to push in additional cards to existing cards and found that this created a smooth even pressure along the display top. At 2-3 card-thickness the last of the adhesive let go, gentle as a baby.

Anthony Zimmerman - Antwort

  • Höre vor der iSight Kamera auf, den Kleber durchzutrennen. Ansonsten besteht die Gefahr, sie zu beschädigen.

  • Schiebe die Karte in Richtung der Bildschirmmitte, um den Rest des Klebers durchzutrennen.

was denn jetzt? Vor der Kamera aufhören, oder in Richtung Bildschirmmitte schieben, um DEN REST zu entfernen? Wenn ich vor der Kamera aufhöre, kann ich nicht alles an Kleber entfernen.

Julia S. - Antwort

  • Schiebe die Karte zurück in die Ecke des Bildschirms und lasse sie dort stecken, um zu verhindern, dass der Kleber den Bildschirm wieder festklebt.

Kommentar hinzufügen

  • Schiebe eine zweite Karte zwischen Bildschirm und Gehäuse an der oberen linken Seite.

Kommentar hinzufügen

  • Drehe die Karte leicht, um den Abstand zwischen Bildschirm und Gehäuse zu vergrößern.

  • Genau wie an der anderen Seite, bewege die Karte nur langsam, damit der Kleber genügend Zeit hat, um sich zu lösen, und das Glas nicht überbeansprucht wird.

Kommentar hinzufügen

  • Schiebe die Plastikkarte in Richtung Mitte und höre wieder vor der Mitte auf, um die iSight Kamera nicht zu beschädigen.

Kommentar hinzufügen

  • Schiebe die Karte wieder an die obere, linke Ecke und lasse sie dort stecken.

Kommentar hinzufügen

  • Hebe den Bildschirm nur einige Zentimeter an. Er ist immer noch mit dem Logic Board des iMacs mit Kabeln verbunden.

  • Wie im Bild gezeigt, inseriere die Karten zwischen Bildschirm und Gehäuse und fange an, diese leicht zu drehen, um den Abstand zwischen Gehäuse und Bildschirm zu vergrößern.

  • Wenn Teile des Bildschirms sich nicht zu lösen scheinen, dann nimm eine weitere Karte, um in diesen Bereichen den Kleber ein weiteres Mal durchzutrennen.

  • Beginne, die obere Seite des Bildschirms nach oben vom Gehäuse zu entfernen.

I would recommend using suction cups at this stage to lift the display.

Marco De Palma - Antwort

  • Während du den Bildschirm mit einer Hand nach oben hältst, trenne mit der anderen Hand das Stromkabel, welches zum Bildschirm führt.

    • Hebe den Bildschirm zwar so weit an, dass du genug Platz hast, um an den Anschluss zu kommen, jedoch nicht so weit, dass du das Kabel dehnst und den Anschluss beanspruchst (~20cm).

Mark all cable connectors with a spot of white correction fluid before removal. This will remove the risk, when reinserting them later, of getting them the wrong way round. Yes - I know they will only plug in one way round, but it does make life easier if you are not in perfect lighting!

Alastair Lack - Antwort

The display cable, the wider one, has a lock on it , usually a plastic tape lift tab to release it, once thats flipped it should come out fairly easily, if your experiencing resistance and the cable isn’t coming out then check for this lock/latch, the power cable just pulls out, just don’t rush it everything should go fine, fairly easy to do with the end result a working iMac

I replaced HDD to SSD and assembled parts again. When I boot up the iMac, I found black lines on display (looks partly not broken).

I searched Internet, and some says graphic card problem, but I didn't touch anything but cable to lift up.

Could the damaged display data cable cause this situation? I hope I could fix this by just replacing the cables..

chansung park - Antwort

Sorry, Black lines is a damaged display assembly ;-{ In the process of removing it you either pushed the tool into deep or you torqued the glass severing the tiny wire traces.

Dan -

Same trouble here, is it cable trouble or connector trouble?

redfoxydarrest - Antwort

Sorry damaged display

I think whenever words like "...is a delicate connection that can be broken. Be sure to pull the [cable in a certain direction] ANYTIME.... It is worth either a closeup or 2, maybe one with annotations or insertion directions and maybe a motion direction arrow with the something like and 'X' char or a circle division slash over the wrong one.

Thank you Stef, that's what i will do next time, i cracked the lower part of the screen went opening very slowly, that's probably why those "tabs are for !!

dforgues - Antwort

Thanks Stef, this has saved me! Simple yet very effective.

David Zemsky - Antwort

Yep, I cracked the lower corner of the display as well. I failed to work the adhesive enough to loosen it sufficiently. Be careful, I just had to buy my customer another screen!

Peter Haigh - Antwort

There seems to be missing a step or two. As I was removing the old display, there are two wires that need to get transferred to the new replacement display. There is not note about these two wires located at the top of the display. The 1.128-inch ribbon cable and then this other 4-inch long, two-wire cable that goes to a very small circuit board that is 1/4 by 3/8 of an inch and seems to be adhered to the panel.I have not been able to get this cable off the old display. There is a port for it on the replacement display.

Note: When ordering this screen, and plastic cards as noted tools, ifixit.com did not list the pizza cutter or the new replacement adhesive strips. So now I’m not sure how to get the new one on and secure.

Todd Derek - Antwort

The adhesive strip along the bottom is designed with a pull tab on each outer end. Rather than lever and pull the screen simply carefully pull the tab which removes that half of the lower adhesive strip and frees up the screen.

Would have been helpful to box the same red area when using the plastic card to separate the glue. Since the red blocked picture is inverted, if someone doesn't pay close attention it may not be obvious that the area of concern is at the right top of the graphic pictures in which the plastic card use is being demonstrated..

  • Sei vorsichtig bei der Handhabung des Bildschirms. Er ist groß, schwer und aus Glas. Die Kanten des Displays sind zerbrechlich. Vermeide es, ihn an den Ecken hochzuheben.

  • Hebe den Bildschirm aus dem Rahmen nach oben und entferne ihn anschließend aus dem iMac. Lege das Display auf eine flache und weiche Oberfläche mit dem Bildschirm nach unten.

  • Möglicherweise musst du an einer Seite anfangen, den Bildschirm langsam anzuheben, um den Rest des Klebebandes zu lösen.

  • Nachdem der Kleber durchschnitten worden ist, kann er nicht mehr zu Verkleben desDisplays verwendet werden. Folge dieser Anleitung, um nach der Reparatur die Klebestreifen zu ersetzen, welche das Display am rückseitigen Gehäuse befestigen.

Kommentar hinzufügen

  • Wenn du das Displaypanel austauschst, musst du wahrscheinlich einige Bauteile vom alten Panel auf das neue übertragen. Vergleiche die Rückseite des alten Panels mit dem neuen. Achte auf alle Kabel, Sensoren und Schaumstoffformteile, welche auf dem neuen Display fehlen.

    • Wenn sich ein Kabel oder ein Draht unter einem Klebeband befinden, dann ziehe das Klebeband immer vorher ab.

    • Wenn das Kabel am Rahmen festgeklebt ist, dann musst du erst die Klebestelle mit einem iOpener oder einem Haartrockner erwärmen. Du kannst dann ein Plektrum unter das Kabel schieben und es ablösen. Ziehe niemals direkt an empfindlichenh Steckern.

    • Schiebe ein Plektrum unter die Schaumstoffformteile, um sie vom Display abzulösen und ziehe sie vorsichtig ab. Eventuell musst du sie mit doppelseitigem Klebeband am neuen Display befestigen.

Be extremely careful removing the LCD Temp Sensor from the rear of the screen. If you pull the wire, you run the risk of severing the metal wire from the connector but not notice it because the surrounding plastic insulation may still be intact. Use a razor blade so “shave off” the sensor under the adhesive. I just had the screen replaced by a local shop and, upon boot, the fan was running full-speed and the Mac’s speed was miserable; Excel took 30 bounces in the Dock to launch rather than the expected 4-5. Novabench showed the Mac running at 4% of its expected speed (overall). The tech examined the sensor carefully, found the broken connection, soldered it back into place, and all was fine. Note that the (partially disconnected) sensor actually showed up when I ran Macs Fan Control in an attempt to work-around this. No problem controlling the fan speed then but the iMac’s running speed was awful until the disconnected sensor wire was fixed.

Two notes here:  If you are using OWC’s Thermal Sensor HDD Upgrade Cable, be sure to tuck the cable under the hard drive slightly.  You cannot allow the connector to sit near the top edge since this will not allow the monitor to sit flush with the chassis when it is reattached.  Additionally, the SATA connector does not seem to fit together as snuggly as when it was connect to the HDD, so tape or a plastic cable tie to keep the connection tight may be good insurance to prevent it from coming loose.

If you are planning on dual booting with Windows 10, the Windows 10 installed failed when the SSD and HDD were both connected at the same time.  I had to disconnect the HDD until Windows 10 was installed.  Note: I did a fresh install on a new SSD not configured as a fusion drive.  If you are planning on doing this as well, use packing tape (or something similar) to hold the monitor in place until after installing the OSs.  Then reconnect the HDD and apply the adhesive to the monitor for a permanent seal.  Good Luck!

Walter Hayden - Antwort

Hi Walter, i’m looking to replace the broken fusion drive with a SSD, do i have to get the OWC’s Thermal Sensor HDD Upgrade Cable?

Gregorio Alvarado Sahli -

Full removal of the speaker is unnecessary - just very carefully unplug the two-conductor power button cable, which is routed through the groove along the edge of the speaker enclosure. Next, unfasten the two large torx screws holding the speaker enclosure to the chassis. Now you can easily scoot the speaker away from the drive mount - move it over just enough to reach the drive mount’s 2 torx fasteners beneath the edge of the speaker (a CM or two). There’s now enough room to easily remove and replace the drive assembly .

Regarding the screws on the power supply board (step 35), I can confirm these are not T10 screws as shown in the guide. In my Late 2015 Retina 5k model, the screws are T8. Morgan mentioned T9 and depending on your T9 driver, it may just barely fit but can easily slip and strip the screw. A T8 driver goes deeper in and holds the screw properly.

This connector was very difficult for me to remove (even after pushing the disconnect tab). Eventually I had to use a pair of needle nose pliers to wiggle it back and forth out of the socket. A lot of the cables on the my late 2015 model were very tight and a struggle to get out.

To reassemble, do the same in reverse but keep power supply board more upright than slanted down when re-inserting it in to the lower right corner. The lower right screw post has an protrusion under/behind it and the Power Supply's small 2 wire plug must fit between the front of your Mac and the obstruction.

      • Diese Schraube befindet sich unter einem Loch in der Hauptplatine. Du benötigst einen festen Schraubendreher oder die 60 mm Verlängerung aus einem iFixit Schraubendreherkit, um dranzukommen.

The central screw is very difficult to reach! Use a long and very thin T10 screw driver

MrSchaeffer - Antwort

On my late 2015 there is another T10 (approx 16 mm long) on the lower edge slightly left of the hole in the logic board giving a total of 4 screws along the bottom edge.

  • Das SATA Festplattenkabel kann im Moment noch nicht entfernt werden, wird jedoch das Entfernen des Logic Boards behindern.

  • Ziehe das Kabel und den Verbinder durch die rechte Festplattenklammer. Lege das Kabel auf die rechte Seite des iMac weg vom Abluftschacht.

  • Drehe zwei 5,7 mm T10 Schrauben aus dem oberen Teil der Kühleröffnung.

  • Kippe die Platine leicht nach vorne.

  • Hebe die Platine nach oben und aus dem iMac heraus. Sei vorsichtig dass du an keinen Schrauben kratzt die im Gehäuseinneren hervorstehen.

  • Beim späteren Zusammenbau musst du darauf achten, dass alle äusseren I/O Ports sauber in die Öffnungen passen. Die Hauptplatine könnte schief sitzen, sogar wenn alle Schrauben befestigt sind.

  • Du kannst einen USB Stecker oder ein Ethernetkabel benutzten, um den korrekten Sitz des Logis Boards zu gewährleisten während du es festschraubst.

To help me line up the IO ports, I filled all the USB ports on the back with thumb drives before I screwed the Logic board back down. Worked like a charm!

  • Hebe die SSD leicht an und ziehe sie aus ihrem Anschluss auf dem Logic Board.

  • Achte beim Wiedereinbau daruf, dass die SSD richtig im Anschluss sitzt, bevor du die Schraube anziehst.

this ssd is not for a late 2013!

this is 2012 year

What do you mean? I'm going to buy a ssd to add it in my imac 27 late 2013 the came without it.

Which part I need?

MrSchaeffer -

I think what he meant to say is the SSD shown (Samsun) is for a late 2013. The 2014 iMac uses a Sandisk unit (see the 5k teardown).

Ifixit have made the mistake of referencing the late 2013 iMac teardown photos here.

Brent -

Actually the picture show the late 2012 pcie connector. (8+18 pins)

(http://www.macbidouille.com/articles/488...)

.

After late 2013, (21.5", 27" and 27" 5K) the connector has changed. (12+16 pins)

(http://www.macbidouille.com/news/2013/06...)

(You can see the actual one here : iMac Intel 27" Retina 5K Display Teardown)

Hello,

So i have maxed out version of 2014 iMac 5k with 3TB fusion drive. I am looking to replace above described SSD with crucial 920 gb ssd. Is there other brands of compatible ssd's you would recommend? Will this new ssd still act as fusion drive or can I install OS X separately on it?

Thanks

If I want to swap the fusion drive with a SSD, do I need to remove the SSD-part of the fusion drive as well or can it be left behind?

I just bought the late 2015 27 5k imac (fusion drive 1tb) and I intent to upgrade everything on it

since in the teardown we see this is the same ssd that was in the macbook pro retina 13" late 2013, and until 2015 macbook pro did not changed the ssd type... I looked for it on ebay, a lot of seller sell those apple used SSDs from some sellers include a Compatible list:

Mac Pro Late 2013 and newer

iMac Late 2013-

Mac mini 2014

Macbook Pro Late 2013-

MacBook Air 13 and 11" 2013-

size, pins, and voltage are always the same, but there is some variations in the Ampere spech. I tried find something about but I couldn't discovery if it will be relevant.

There are 2 and 4 lanes versions (4 is faster)

also there are samsung and sandisk options (any doubt abou the better?)

I ignored the amperage diference and bought one that is 2,5A (samsung MZ-JPU256T/0A6). the late 2015 came with a no specified manufacturer and no specs on it. I did right or a mistake?

Vey sorry for so late answer , I didn't saw this at the time. I was revising today the process and saw the question. It worked perfectly for me. You have of plenty options when installing the blade SSD, the better is also put a regular Sata SSD and have 2 SSDs. I also changed the i5 for a i7. It is a long time work but is not that hard, once you are opening the iMac worth change the processor. The used by apple in their upgrade option was the: i7 6700K 4.00 GHz Unlocked Quad Core Skylake Desktop Processor, Socket LGA 1151

Hi, does it still work as a “fusion drive” or two separated drives?

I have a quick question, on the owc site they show you don't have to take the logic board out. You can actually replace the stock 7200 HD with a new bracket and a SSD, attach a heat sensor, plugin, and put screen back on.

Is that also a correct way to upgrade the system? I have a MK462/A1419 system that I want to replace the HD and add and SSD to the system. As a 2nd choice, am I able to add a SSD to the logic board that will now act as a fusion drive with the original HD in place? Thanks for all your help.

intoximacated - Antwort

To add an OMC 2TB SSD where the original HDD went requires changing out the cable, about a $30 part, but one that requires removing the main logic board. While there stuff in as big of a blade SSD as possible.

I own a Late 2015 27” iMac 3.2 GHz Quad-core Intel Core i5 with Retina 5K display and 1 TB HDD. I find it slow and want to install a Fusion Drive.

Hi guys, I'm Rik from Florence. Today I went to a apple reseller because my imac 5k 27 has only one 250gb ssd, without any other disk. They told me that my imac is not upgradable because inside there aren't any cable for an other disk. I asked if was possible to remove my ssd with other bigger but they said that maybe the ssd inside the imac is settled. Any other official upgrade on my imac is forbidden and will cause the warranty end. I think it's a shame. I paid more than 3000€ for an not upgradable computer??? ps. sorry for my poor english

ilminia - Antwort

Okay, so the late 2015 (October) 1TB Fusion has a 24gb SSD and a 1TB HDD in combination - My understanding is that the earlier 1TB Fusion Drives were 128GB SSD + 1TB HDD - and were mounted separately. What I am not sure of is whether the tiny 24gb is mounted on the logic board like the larger ones, or mounted inside the larger disc like some of the Seagate SSHD hybrid drives. That is my first question.

As to the question of whether the sockets for SSD are still in place to add a SSD to the iMac units that only come with the larger HDD, I think that was answered yes above. Now about the iMacs that come with only small SSDs (256 or 512) is there an unused SATA connector on the logic board where you could add a SATA cable and install another disc (SSH or HDD)? I do know there are cables available if the socket is there.

I'm about to pull the trigger on a late 2015 unit and wonder whether I want to get one with the 1TB HDD and add two big SSDs or just pay the extra $500 to get the model with the 2TB Fusion?

Uncle Reggie - Antwort

Hi Guys and SSD Experts .... :-)

I needa a hint from your end ... because I'm a little bit confused because most descriptions that I found are showing how to replace the internal HDD against a SSD.

I purchased a iMac 5k 27, with internal 256 SSD. from the Apple Store in 2015.

So it's a pure SSD Model (no Fusion Drive).

Now I would like to upgrade the 256 SSD with a larger 1 TB SSD.

My thought was that the iMac 5k SSD Version runs a normal 2,5 " SSD.

Is it possible to buy a normal 2,5 " SSD with 1 TB and to insert it at that place where normally the Fusion Drive is located?

Do I need any specific set of cables, etc because of an thermal sensor?

I prefer to runt he iMac with an larger internal SSD. So an external Thunderbolt SSD isn't my preferred option.

Thanks for any comments, support.

G. M. - Antwort

You have a 2.5" SSD and not a blade SSD? If your iMac has a 2.5" SSD, just remove the screen, remove the left speaker for access to the left hard drive bracket, unscrew and remove the left hard drive bracket, unplug and remove the SSD and install the new one.

If however your iMac came with a blade SSD only, you can install a 3.5" HDD or 2.5" SSD, but you need a mount to fit the 2.5" SSD in the 3.5" HDD bracket, if there's even a bracket there at all. If not, find a creative way to keep in it place I guess...

You also need a specific SATA cable (see guide I linked below). Use it as a reference to see where the HDD/SSD is mounted and where the SATA cable needs to plug in (it's not a normal SATA cable). I was able to connect the it without removing the logic board, but it's not easy as the logic board is installed backside up. It needs to connect to both its on-board power connector and the on-board SATA slot:

No, unfortunately. The proprietary Apple SSD has a unique slot configuration. It just simply won't fit. I've replaced the SSD of my iMac 27 5k and had to buy the SM0512G.

Hi there,

I would like to add a 256 GB PCIe SSD on my iMac 27 5k late 2015 which only has 1TB HDD. I read that it has the PCIe interface to install a blade SSD but I cannot find any on the Internet. Can someone please suggest me possible sellers (especially in Europe)?

Thanks in advance

Francesco - Antwort

iMac 27 5k late 2015:

Forgive me if this was asked already — but if I want to switch from a 24gig ssd / 1tb hdd fusion configuration to a strictly ssd config, which PCIe SSD can I use? I wrote OWC to see if I can use any of their PCIe blades, but they wrote back that they don’t make one that works for this model — but now that I’m doing a little more digging it looks like I’m finding old eBay listings for the SM0512G that point to it being used in the Macbook Air line.

Anyone have luck with an OWC PCIe blade as their main drive? Any lucky with a Macbook Air SSD?

If I’m going to upgrade to a SSD, I want it to use the fastest connection possible so the 2.5 drive isn’t optimal.

Any help appreciated, have a great day.

I remove the fusion drive(24GB ssd blade and 1TB hdd) and added a 512MB ssd blade(MZ-JPV5120/0A4) and 1TB ssd(Samsung).

The blade is doing read 1800MB/s and write 1400MB/s so I am happy with the upgrade.

BUT when I check the system preference, NVMexpress option tells me that there is no hardware…

(when the fusion drive was installed, it showed properly 5GT/s and 4 Lane…)

Depending on how your iMac was configured when you bought it, you may have both an SSD (shown in the guide you’re viewing now) and a standard spinny drive. If you’re looking to replace the spinny drive, the guide you want is this one.

Hi guys im thinking of upgrading my ssd blade . Ive been looking about and noticed the do a m.2 convertor Would this be possible to do and just buy a m.2 ssd ?. If not im looking into leaving that there and upgrading the hdd to Evo 850 ssd , Do i need the sensor kit , and i do need to un-pair the Fusion Drive. Thank you Guys

master.mark - Antwort

For all: when swapping out either the blade or the HDD from a Fusion setup, you have to do a full backup to an external drive. Removing a drive will BREAK the Fusion drive like removing a drive in a RAID array.

After you upgrade, you have to re-create a fusion drive of the Blade and the spinner HDD. Google “do it yourself fusion drive” or search macsales.com (blog). After you build the new fusion drive, you can restore your backup to it (easy with CarbonCopyCloner, SuperDuper, etc.) You can even make a fusion of two SSDs.
