Einleitung
Diese Anleitung zeigt dir, wie du Apples proprietäre Blade SSD (AHCI/SATA) austauschen kannst.
Die Anleitung bezieht sich auf die iMac Intel 21,5" EMC 2544 Modelle mit höheren Spezifikationen, die mit einer SSD ausgestattet sind . (Fusion Drive oder Blade SSD Konfigurationen)
Was du brauchst
-
In diesem Schritt verwendetes Werkzeug:iMac Intel 21.5" Cardboard Service Wedge$4.99
-
-
Beginne an der linken Seite des Displays, auf der Seite der Ein-/Aus-Taste, und schiebe das iMac Opening Tool zwischen Das Glaspanel und das Rückgehäuse.
-
Arbeite vorsichtig! Das Glas bricht leicht, wenn es zu stark belastet wird. Erwärme die Kanten mit einem Haartrockner und löse das Klebeband ab, wenn die Raumtemperaturen niedrig sind.
A thin razor blade works well, but be careful to angle the sharp edge AWAY from the glass. Whatever tool you use you can easily scratch the paint on the back of the glass, which will show up when you look at he reassembled Mac on an angle later.
This was a great guide!
-
-
-
Benutze das Werkzeug wie einen Pizzaschneider - rolle es entlang des Schlitzes und es wird den Schaumkleber in der Mitte durchschneiden.
-
Fahre mit dem Werkzeug entlang der linken Displayseite.
-
-
-
Schneide den Kleber entlang der oberen Displayseite durch.
-
Du solltest mit dem Gerät immer etwas durch den Teil vor- und zurückrollen, den du bereits durchgeschnitten hast, um so viel wie möglich von dem Kleber zu lösen.
-
-
-
Schneide den Rest des Klebers an der rechten Seite des Gehäuses bis ganz nach unten durch.
-
-
In diesem Schritt verwendetes Werkzeug:Plastic Cards$2.99
-
Beginne an der oberen rechten Ecke des iMacs und schiebe eine Kunststoffkarte zwischen Display und Rahmen.
So sorry. Thanks for that caution.
Using suction cups (the ones that were made for removing the magnetic front glass on the 2011 and earlier iMacs) work well too. Place one in each top corner, while the Mac is lying face up on a table, and gently pull and it will separate the display from the main body. You might need to do a little more slicing around the edges if you did not get all the way through the first time with the roller. Then you can lift the display up at an angle to disconnect the cables.
This was a great idea, worked well for me. Thanks!

-
-
Drehe die Plastikkarte leicht, um den Abstand zwischen Display und Rahmen zu vergrößern.
-
Bewege die Karte vorsichtig und langsam, und beanspruche das DIsplayglas nicht übermäßig. Eine Lücke von einem halben Zentimeter ist ausreichend.
-
-
-
Schiebe die Karte in Richtung der Mitte des Displays, um den Rest des Klebers an der oberen rechten Ecke durchzutrennen.
-
-
-
Schiebe die Karte wieder in die obere rechte Ecke und lasse sie dort stecken, um zu verhindern, dass der Kleber das Display wieder festklebt.
-
-
-
Schiebe eine zweite Karte in den Spalt zwischen Display und Rahmen an der oberen linken Ecke des iMacs.
-
-
-
Drehe die Karte vorsichtig nach oben, um den Abstand zwischen Display und Rahmen leicht zu vergrößern.
-
-
-
Schiebe die Plastikkarte in Richtung Mitte und höre wieder vor der iSight Kamera auf.
-
-
-
Schiebe beide Plastikkarten zwischen Display und Gehäuse und fange an, sie leicht zu drehen, um den Abstand zwischen Gehäuse und Display zu vergrößern.
-
Beginne, die obere Seite des Displays vom Rahmen hochzuheben.
-
-
-
Während du das Display mit einer Hand nach oben hältst, trenne mit der anderen Hand das Stromkabel des Displays. Achte darauf, dass du das Kabel nur an der Plastiklasche herausziehst, und nicht an den farbigen Drähten.
-
-
-
Klappe die Metalllasche am Anschluss des Display-Datenkabels mit einem Spudger hoch.
-
Ziehe das Display-Datenkabel vorsichtig aus seinem Sockel auf dem Logic Board.
-
-
-
Hebe den Bildschirm an, bis er fast senkrecht ist.
-
-
-
-
Fasse die kleine Lasche am Ende einer der Klebestreifen an der Unterkante des Displays, ziehe sie zur Oberkante des iMacs hin und entferne sie.
-
Wiederhole das Ganze für den anderen Klebestreifen.
The roller tool for slicing open the display works great for this step. Get in there like using the card and roll across the bottom to slice through the remaining adhesive.
-
-
-
Hebe den Bildschirm nach oben aus dem Rahmen heraus und entferne ihn aus dem iMac .
-
Möglicherweise musst du an einer Seite den Bildschirm anheben, damit sich der Rest des Klebebandes ablösen lässt.
After removing the display, I also removed the 3 screws for the processor fan, disconnected the power connector for it and set the fan shroud aside. Disconnecting the remaining cable (similar style to 1 of the cables for the display) that is in the way of the RAM chips is all that's left to do. I was then able to access and quickly remove the two Apple-provided RAM chips, and replace them with 3rd party RAM. Turning the iMac on its side, so that it's in a position where you're physically putting the RAM chips DOWNWARD into their respective slots is the best way to go about uninstalling and reinstalling the chips. Using a narrow but long'ish plastic spudger tool is the best way to defeat the spring-tabs which hold the RAM chips in place. After removing the LCD display, changing the RAM is about a 10 minute process!! And I'd SURE prefer not to remove all the parts and risk damage to the iMac via the standard procedure listed. As per usual, take your time and work gently :-)
Teardown the whole machine just to change RAM? While preparing to comment on this procedure I just noticed the comment made by Mitch K above. I ran pretty much the same procedure that he describes this afternoon (steps 1-23, 43-45, and step 55). Then I swapped out the original 2x4GB RAM chips for 2x8GB chips by reaching behind the logic board, releasing the spring retaining clips one chip at a time (starting with the chip further away from the logic board), pivoting the RAM towards the back of the machine, and then carefully sliding it out of the slot. I easily slid in the new chips and then pivoted them to lock them down. No hassle, no time lost. As Mitch K states above, not only is this “shortcut” method much quicker and easier, but it provides less risk of damaging cables, sockets and other delicate components during a total teardown. Why mess with the power supply board just to change RAM? I do not advise to follow the current iFixit.com procedure written by Sam Lionheart, regardless of user skill-level.
THAT sounds one !&&* of a lot easier than the full tear down. I wonder if there’s a video of the process described by Mitch K? Adding that to these verbal instructions would really help relieve the apprehension and anxiety around the process! I do sometimes find the additional warnings, though appreciated from a “safety first” perspective, are somewhat overstated. It’s been a very long time since I shorted out RAM, or fried a PCB, or broke a connector, regardless of how finicky, fragile or awkwardly designed and positioned. I may have WANTED to break something, and the air might be blue for a few seconds, but inevitably, things go back together, the start button gets pressed, the startup chime sounds, and we’re in business. Practice DOES make as close to perfect we are likely to get.
Mitch has the exact method that works a treat. You don’t need to follow steps 24-37 and also 40-63. Step 51 is the step to remove the camera cable and is needed. Steps 38 and 39 are for the Fan. That is all that is needed. Done quite a few like this.
Be careful not to drop the RAM down the back of the logic board!
By NOT removing all the other stuff you can avoid either damaging it or forgetting to plug in a cable.
I just trued this shortcut and it was not successful. I was not able to seat both RAM chips with this shortcut, and managed to slightly damage one of the retainer clips. I simply could not manipulate the chips into and out of the slots effectively without taking everything apart as described in the full set of steps.. I ended up retracing my steps and following the entire procedure, carefully, and that worked without incident. So, bottomline, it is definitely more work to follow all the steps but from my experience, it is decidedly safer. Your mileage may, of course, vary. It was successful in the end, and I swapped out the hard drive with an ssd during the same procedure and my machine is very, very much faster.
I have completed by following the Mitch K post and it is much easier than stripping down the whole thing, just be aware that to remove and replace the ram chips means working in a tight space, you need slim fingers and don’t be tempted to use force, take your time.
Well, I have slim fingers, but they are 60 years old, and they don’t work like they used to! LOL.
Agree with Mitch K’s procedure. The only added tip I would throw in is to use two 45 degree tweezers with their plastic covers still installed to easily pop loose the RAM. I couldn’t get the plastic spudger tool to work myself, but the tweezers easily reach the RAM clips. Just make sure the plastic covers are installed and you won’t be in danger of scratching or shorting anything out.
So thankful I discovered these comments. Saved me a TON of time! Thank you!!
These comments were very useful. Thank you. I just needed to modify a pair of tweezers to allow me to seat the new RAM more easily. The ifixit screwdriver wasn't able to turn some of the screws as they were installed too tightly, and I didn't want to wait to order and reveive a pair of right angled Torx screwdrivers that would give me more leverage to get those boards off.

Entferne folgende fünf Kreuzschlitzschrauben, welche die untere Displayhalterung befestigen:
-
Vier 3,2 mm Schrauben
-
Eine 1,7 mm Schraube
-
-
-
Entferne die untere Displayhalterung von der Gehäuseöffnung.
Of all the parts of this entire procedure, replacing this one piece is the hardest part! The screws are tiny and they just don’t seem to want to grab the support piece. Also it seems to perform no function which is also annoying.
I left mine out. LOL
Line up the screw holes and press on the bracket from the back to help the screws grab. If your fingers are too big, press with the flat side of your spudger. As long as there’s no gap between the bracket and the iMac’s frame, the screws should grab easily.
I put it in at a slight angle lining up the right hand side holes, screwed in the two screws and gently pressed my finger behind it on the rest
If you only want to replace the HD and RAM, take a big shortcut and leave the logic board in, as well as all the parts needed to remove it (speaker, power supply etc). Once the display is removed, just take out the fan and the top two logic board screw. There is than sufficient space to gently remove and insert the two ram modules. HD can easily be replaced with an SSD by just removing the HD mounting brackets...
Voces mudaram de modelo iMac, desta foto para proxima, esse modelo desta foto nao tem slot nvme. O da proxima foto sim. Voces me fizeram comprar un nvme por engano...

-
-
Löse den Stecker am Kabel des rechten Lautsprechers von seinem Sockel auf dem Logic Board.
-
Ziehe den Stecker nach unten, um ihn aus dem Sockel zu lösen.
I highly recommend doing steps 27 and 28 first and then pull out the cable. It will give you more room on the right side of the cable to work with making this step that much easier.
The two corners of the connector are latches that need to be pushed toward the center of the connector to release. This is easily done with the pointed end of the spudger. Once the two corner latches are released, the connector comes apart easily.
-
-
-
Entferne die beiden 10,0 mm T10 Torx Schrauben, welche den rechten Lautsprecher am Rückgehäuse befestigen.
-
-
-
Ziehe den rechten Lautsprecher oben etwas mehr als einen Zentimeter weg vom Rückgehäuse. Dadurch wird das Antennenkabel an seiner rechten Seite sichtbar.
-
-
-
Setze eine Spudgerspitze zwischen den rechten Lautsprecher und das Antennenkabel, welches entlang der rechten Seite des Lautsprechers verläuft.
-
Lasse den Spudger entlang der rechten Seite des Lautsprechers nach unten laufen, um das Antennenkabel so aus seinem Kanal herauszuholen.
-
-
-
Ziehe den rechten Lautsprecher etwa 2,5 cm zur Oberkante des iMac.
-
Hebe den rechten Lautsprecher gerade nach oben und entferne ihn vom iMac. Das braucht wahrscheinlich etwas Kraft und beide Hände. Ruckle dabei den Lautsprecher nach links und rechts.
-
-
-
Entferne folgende Torx T10 Schrauben, welche die Festplattenhalterung am Rückgehäuse befestigen:
-
Zwei 21 mm Schrauben an der linksseitigen Festplattenhalterung
-
Eine 9 mm Schraube
-
Eine 27 mm Schraube
Pay attention to this photo and where the fan is. It is 180° from where the previous step shows it is oriented to you.
-
-
-
Drücke mit der Spudgerspitze abwechselnd auf jeder Seite des Steckers am Kabel zum Netzschalter und lasse ihn vorsichtig aus dem Sockel "herauswandern".
-
-
-
Drücke vorsichtig mit der Spudgerspitze abwechselnd an jeder Seite des Steckers der Netzteilsteuerung nach oben, um ihn aus seinem Sockel "herauswandern" zu lassen.
-
-
-
Entferne die beiden 7,2 mm Torx T10 Schrauben, welche das Netzteil am Rückgehäuse befestigen.
What if these are too tight to remove?
Hi Rafael,
Be very careful not to strip these screws. Use a new, accurate T10 bit and a driver with good leverage to loosen these screws.
They are T9 in my iMac
They were T8 screws on my machine.
-
-
-
Ziehe das Netzteil leicht hoch und aus dem Rückgehäuse heraus.
-
Drehe das Netzteil gegen den Uhrzeigersinn, so dass die rechte Seite etwa 2,5 cm höher als die linke ist.
-
-
-
Schiebe das Netzteil nach rechts um es von den Schraubenpfosten am Rückgehäuse zu befreien.
-
-
-
Drücke die Lasche am Stecker der Gleichstromversorgung zusammen und ziehe ihn gerade aus seinem Sockel auf der Rückseite des Logic Boards.
what happens if you damage the power socket on the logic board?
The tab is on the bottom of the connector. You can’t see it. Squeeze the bottom of the connector close to the cables to properly release tab. Pulling straight out is important.
This step might be easier if you do the next step first (step 41) and then come back to this step.
I loosened the logic board attached to the power supply board. I then could easily remove the 2 power cables.
In the photo above, the index finger is shown squeezing the connector locking tab. Do this while using the flat end of a spudger to release the latch. Once the connector is moved about an eigth of an inch the latch is released and the connector should come out freely.
-
-
-
Drücke die Raste an der Seite des Steckers des Wechselstromkabels mit dem flachen Ende des Spudgers nach innen.
-
Halte die Raste mit dem Spudger gedrückt, fasse das Wechselstromkabel an und ziehe den Verbinder aus seinem Sockel.
-
-
-
Ziehe vorsichtig den Stecker des Lüfterkabels gerade aus seinem Sockel auf dem Logic Board.
I don’t like to pull on wires as shown in the photos above. I used my index fingernail on the top corner of the connector and the pointed end of a spudger on the bottom corner to pull the connector straight out of its socket.
-
-
-
Entferne die drei 12,3 mm Torx T10 Schulterschrauben, mit denen der Lüfter am Rückgehäuse befestigt ist.
-
-
-
Hebe die Festplatte am Rand, der am nächsten vom Logic Board ist, hoch und ziehe sie leicht aus ihrem Sitz.
-
-
-
Entferne die einzelne 7,2 mm Torx T10 Schraube, welche den Festplatteneinschub am Rückgehäuse befestigt.
-
-
-
Entferne den Festplatteneinschub vom Rückgehäuse.
Cables are routed through the backside of the tray. Take a picture for reassembly.
-
-
-
Drücke abwechselnd mit der Spudgerspitze an jeder Seite des Steckers vom linken Lautsprecherkabel und lasse so den Stecker "herauswandern".
As noted in the right speaker cable section, the two corners of the connector are latches that need to be pushed toward the center of the connector to release. This is easily done with the pointed end of the spudger. Once the two corner latches are released, the connector comes apart easily.
-
-
-
Fädle das linke Lautsprecherkabel aus, indem du es direkt aus seiner Halteklammer hinten am Rückgehäuse herausziehst.
-
-
-
Löse in gleicher Weise wie im vorigen Schritt die SATA Datenkabel und Versorgungskabel aus der Halteklammer.
-
-
-
Klappe den metallenen Sicherungsbügel am Stecker des Kabels zur iSight Kamera mit dem flachen Ende des Spudgers hoch.
-
Ziehe das Kabel zur iSight Kamera gerade aus seinem Sockel auf dem Logic Board.
-
-
-
Löse die vier Antennenstecker mit der flachen Kante des Spudgers von der AirPort /Bluetooth Karte.
I broke off one of the antenna connectors when I took off the antenna wires, but the new 802.11ac card is working:) I seems the way to take off the wires is lifting it up from the wire side. In hindsight I just wasn´t careful enough.
how do I check a working logic board
If you have a pair of angled tweezers, they work well for grabbing under the connector so that you aren’t pulling on the wire. The head of the T10 screwdriver works well for pressing them back on.
iMac 2017 EMC 3069 this has the antenna brackets with two T5
-
-
-
Hebele den Verbinder des Kabels zur Kopfhörerbuchse mit dem flachen Ende des Spudgers aus seinem Sockel auf dem Logic Board.
Unlike the rest of the connectors on the logic board, this one lifts up away from the board rather than to the side. That “Push the cable slightly to the right.” notation is after the connector is free.
-
-
-
Entferne folgende Torx T8 Schrauben, welche den Lüfterkanal am Rückgehäuse befestigen:
-
Zwei 6,3 mm Schrauben
-
Zwei 4,7 mm Schrauben
Weirdly, these screws didn’t work with my T8 driver. Not with T6 or T10.
Every other screw (to this point) has been fine. Hmm.
??? The T8 worked fine for me. Not sure what the difference would be.
Fare molta attenzione alla vite in fondo a destra, è facile (soprattutto se la punta del proprio cacciavite non è magnetizzata) che la vite si perda sotto alla Logic board. Se la punta del cacciavite non è magnetizzata consiglio o di utilizzare un magnete esterno o di utilizzare delle pinze mentre si svita la vite in modo da non incorrere in questo problema.
-
-
-
Entferne die vier 7,2 mm Torx T10 Schrauben, welche das Logic Board am Rückgehäuse befestigen.
When reinstalling the logic board, install four screws loose. Insert thumb drives into the back in all slots to ensure alignment. Once aligned, then tighten screws.
On some models there is a tiny microphone cable connector, just above the lower left logic board screw. Remove by carefully pulling straight down. There is also a piece of insulating plastic w/adhesive on top of the screw which can be pulled off prior to removal. Save and reuse with the same screw on installation.
-
-
-
Kippe die Oberkante des Logic Boards weg vom Rückgehäuse.
-
Hebe das Logic Board gerade hoch und aus dem iMac heraus.
When inserting the logic board back, pay attention of the position of the I/O connectors. When it is back in place, put a USB / Thunderbolt cable into the connectors to ensure the perfect alignment.
This is fantastic advice. I used a combination of USB and display port plugs to ensure proper alignment and help keep the logic board steady while i screwed it back in. Thank you!!

ive gotten this far and i still have one question, i’m replacing my HDD With A SSD should i also remove the original Blade drive ? and run exclusively off the ssd, ? i wasn’t 100 on whether or not i was getting the fusion set up so i’m not in possession of a upgraded blade, so i though this was a good question id hadn’t seen asked.

Entferne die einzelne Torx Schraube, welche die SSD am Logic Board befestigt.
My wife’s iMac Late 2013 21.5” did not originally have a blade SSD installed, so there was no existing Torx T8 screw available to use on the Aura 6G I was installing. Had to use one of the 4 T8 screws from the Exhaust Duct to get the job done.
Was the iMac have a fusion drive? I´ve just read that 21,5" iMacs without Fusion Drive or SSD don´t have the PCI-e slot activated. Could you confirm please?
@danielcalde2053 - A HDD only system won’t have the connector or added circuitry to support the Blade SSD. With that said people have altered systems! Taking out the wimpy Fusion Drive cache SSD as they often fail. So you might find a HDD system with a working slot!
Dan -
I picked up a late 2013 EMC No. 2638, model A1418, at a local recycle center. Everything I read indicated this entry level iMac wouldn't have an blade SSD connector installed, but I had to look anyway while I replaced the HDD with and SSD. Guess what, the blade connector was installed on the motherboard. I also read that many had problems with aftermarket adapters, including fit, sleep issues, etc, so I opted for a used Apple blade (512 GB) from macsales. I didn't need a killer system, just a back up for my other old iMac machines. It works great, with the help of OCLP I'm running Sonoma, typing this comment on it now.
Patrick, you were lucky! Likely was a Fusion Drive’d system someone took the SSD out as these often failed as they really can’t handle the constant R/W cycle stress for such a small SSD.
Dan -
Read somewhere that a certain type of adapter is needed to use a "Samsung 970 EVO Plus NVMe M.2" in either a 21.5" or 27" 2017 iMac. Does anyone (most likely @danj ) know if it will work?
Long term goal...have both sizes of 2017 iMacs. Plan is to install a faster i7 cpu in 27" and migrate 3.4 GHz i5 to 21.5" to replace 3.0 GHz i5 in 21.5". While inside 27", will replace fusion drive with the EVO plus and perhaps had a larger 7200 rpm HD or perhaps a 2.5" SSD.
While inside 21.5", i plan to upsize SSD from 500 Gb to 1 or 2 Tb. Not sure which ssd form factor is currently inside but i believe it is a 2.5". Does anyone know if there is a drive cavity in a 2017 21.5" iMac to fit a full size HD (to possibly use a stacked pair of notebook size SSDs?
Thanks to all in advance!
I really don’t recommend using M.2 SSDs in iMacs as they are a bear to open up to get to the SSD socket and many adapters/SSD sets are flaky!
If this is a system which has important work I would stick with either an Apple or OWC bade SSD. Yes, I know! You want something with more performance. Sometimes it doesn’t pay 😖I had wished Apple would have gone with the standards based M.2 SSD’s their greed set the course! The rub is Apple has other lines in their SSD’s these adapters and M.2 SSD’s don’t offer which will bite you when your drive gets full as the wear-leveling and housekeep functions use these lines.
As far as Samsung 970 EVO Plus drives you will need to update its firmware as they did have a few interoperability issues with macOS when used in MacBook Pro’s
Dan -
@danj I did get this blade SSD from OWC and it is working fine. My wife only uses this for non mission critical work now since she has a 16" MBP, but it sure beats the pants off of the old HD that shipped with the system. :-)
Sorry I grabbed the wrong text to reply. Even still you wouldn’t want to loose your stuff 😢

If i want to add a news ssd at my iMac? Actualy is a model without a ssd
Which kind of SSD can I install? Is this the normal M.2 connector?
Thanks in advanced..
It is a special blade SATA drive, essentially just a SATA SSD with special connector. Same form factor as in 2012-2013 MacBook Pro Retinas. You can install a normal M2 SATA (not NVMe!), but with an adapter
oldnwstf -
Remember guys: the base model that did not ship with SSD is completely missing the M.2 connection soldered on the board from the factory, and will not be able to mount one. The main HDD can still be swapped for one though.
I have an iMac 21.5 Late 2012 (2.7GHz i5) and I was thrilled to find a vacant Apple SSD slot!
I have since installed an SSD and I am creating a Time Machine backup.
A fusion drive will then be created and the data migrated.
Also really nice to know the RAM can be upgraded to 16GB at some point :)
At first glance I was sure this iMac would not be upgradeable but it just goes to show, you should always physically check!
Early 2.7 GHz models did not have the slot on the motherboard.
Later ones did.
OWC Aura 6G fits...
Hy, my iMac, has the PCIe SSD blade slot. I’ve opened it and checked it. It is there, waiting for something to be filled in:))). From your post I understand that OWC Aura 6G should work if my slot is there, altough on their site, they are particulary telling that it s not compatible.with 13,1 2.7 late 2012 , only with 2.9 and 3.1. Do you think that they are talking about the late 13,1 2.7 2012 models without PCIe M2 slot…..?
Thanks
The 2012 & early 2013 models use a different SSD than the late 2013 model. Review this great guide The Ultimate Guide to Apple’s Proprietary SSDs

At the bottom, it says Mac (21.5-inch Late 2012)
(October 2012)
Model ID: iMac13,1
2.7GHz
with a :”Not Compatible” warning.
Click on the “compatibility Info” link.
In very small print, at the bottom of the warning…
“The initial production of the base model for the 21.5" iMac didn't come with a slot for the SSD. Later production models included the SSD slot, but there's no way to determine if the 2012 21.5" iMac with a 2.7GHz processor has the SSD slot without opening it up to see if it's available. If you have already opened the iMac up and it does have an SSD slot, this SSD is compatible.”
Ich habe einen iMac 21.5 Late 2012 (2.7GHz i5) mit 8 Gb Arbeitsspeicher und 1 TB HDD. Die HDD war mit 640 GB voll und sehr langsam. Nach Recherchen im Internet bin ich auf ifixit gestoßen und habe die Anleitungen für die RAM Erweiterung auf 16 GB und eine Blade SSD Aufrüstung gelesen. Nach Bestellung des Opening Kits, einer Speichererweitung 2 x 8 GB von Crucial ( ca. 80,- € ) und einer Blade OWC Aura 6G 480 GB SSC ( 120,- € ) wurde der iMac nach Anleitung geöffnet, zerlegt und die Erweiterungen eingebaut. Alles funktionierte dabei bestens wie beschrieben ! - Die HDD wurde danach auf 450 GB verkleinert. Mit Carbon Copy Cloner eine Copy der HDD auf SSD erstellt und anschließend das Startmedium geändert. Der iMac läuft jetzt wie neu

I just realised that my iMac had an SSD connector… I got it used, but it didn’t show a fusion drive, but when I took off the logic board, I found an empty apple M.2 connector! I am going to get my Apple SSD from my MacBook Pro…
Not to fast here! This series used a different than the newer MacBook Pro’s

I have (21.5 inch, mid 2017, 2.3 ghz) base model same as this but not 4k. How much max ram can I install in my iMac??
Narendra Verma - Antwort
This guide contains many extra steps for what should be a straight forward, simple parts replacement without disturbing more than the display, left hand speaker and removal of 4 logic board screws for play. Nothing else except for the left hand speaker wire & iSight cable from logic board, the lower support bracket and loosening the speaker so as to move it around a bit.
For the ram, I bent a pair of cheap tweezers long ago supplied with these replacement kits to the perfect angle for holding, locating and inserting the ram into the slots under the logic bd after moving each retainer w/spudger and popping out the old. Pay attention to the orientation of the ram when removing/inserting the ram! An automotive mirror is handy along with a small flashlight for closeups. Once the ram is aligned properly substitute your fingers for the tweezers, ease it into the slot, push up & engage! Reinstall screws and all else. I have done this job successfully this way countless times. For a tweezers pic contact me!

Additionally, if a blade is present, I install the OSx system on the blade and everything else, apps and home folders on the new SSD. You get the very fast boot off of the blade and the full ssd for all else!
