  • Entferne die im Bild gezeigten acht Schrauben, die die Bodenplatte mit dem Rest des Gehäuses verbinden:

    • Eine 3 mm Kreuzschlitzschraube.

    • Drei 13,5 mm Kreuzschlitzschrauben.

    • Vier 3,5 mm Kreuzschlitzschrauben.

On my model, it seemed the top-left was 3.5mm and the bottom 4 were 3 mm.

Jim - Antwort

Make sure you have a good quality Phillips screwdriver. Mine had removable tips and had a small play at the connection. As a result I didn't have a good feel and damaged my screws (those securing the fan and the top left in step 23). Game over for me installing new thermal paste...

Be very carefull with your screws! Especially those on the inside.

Nickolas Michelinakis - Antwort

You can get away with a Phillips #00 for many of the screws involved but the 4 at the bottom case split are likely to strip if you don’t use a JIS #00 or, in a pinch, a Phillips #000.

  • Verwende das Flache Ende eines Spudgers, um den Subwooferanschluss gerade nach oben vom Logic Board zu entfernen.

Me, too, broke the subwoofer connector from the motherboard. I'd suggest removing the padding first so that you can see what kind of connector it is, then pry it loose (insert spudger where the cables enter the connector).

petterwolff - Antwort


You can complete this guide without doing step 6 just BE CAREFUL as you already should be.

kenneth rhem - Antwort

The subwoofer cable is NOT removable on some models, attempting to remove it, brakes it off the circuit board and them you are @@%#$$, like me. Thanks iFixit. Also it is not necessary to remove it to replace the optical drive.

Badruddin Hisbani - Antwort

Just “4 small tin marks” is what the the motherboard half of the subwoofer connector looks like.

Bill Cole - Antwort

There are two variants of this connector. In one, there are pins that come up from the motherboard and the connector can be pried directly up without damage.

The other variant of the connector that everyone commenting here has is soldered to the motherboard. To repair this type, first pull off the small square of foam padding on top of the connector. Then gently pull out the four black and red wires, leaving the soldered connector attached to the logic board. After you have installed the new speaker and subwoofer, you will remove the connector on the replacement component and carefully feed the red and black wires into the connector that is still attached to the motherboard (paying careful attention to their correct order). Then replace the square of black foam.

If you have removed the soldered on the connector, your two options are to solder it on yourself or to find a repair shop that can do that for you. There are instructables online for soldering tiny components that can help you.

This step is not necessary. Drive can be released without removing the screws.

mcbohdo - Antwort

If you’re replacing the subwoofer, you DO need to remove the left screw but not the right screw. This is fortunate, because if you are stuck with a Phillips #00 instead of a JIS #00 screwdriver, you may well strip the heads of these screws.

The bay and dvd drive cable at iFixit is $40.00 (Unibody Laptop Dual Drive)

But for $10 more you can get an external casing that will protect your super drive form MCE (http://store.mcetech.com/Merchant2/merch...) A total of $50 dollars. It is what I used and works great and looks pretty and is guaranteed to protect your superdrive. MCE also gives you a disk with software to patch the DVD Player to work with external dvd drives. So For an extra $10 dollars you get better software functionality and a case for your super drive. It works great.

Robert Wacker - Antwort

Robert, do you by chance also know where to buy an external drive case to make the old hard disk an external portable hard disk ?

Early 2011 MacBook Pro was running slow with its 2TB hard drive running at 5400rpm. The DVD drive was almost never used. The iFixit part allowed me to place the hard drive in the DVD bay and place an SSD drive where the hard drive originally sat. Now the computer fires up almost instantly and runs so much cooler as the 2TB hard drive is only accessed as needed. A stunning transformation for a 7 year old laptop.

Paul Cline - Antwort

  • Achte darauf, dass die Anschlüsse für die Festplatte nach unten zeigen, bevor du die Festplatte in das Gehäuse setzt.

  • Setze die Festplatte vorsichtig in den dafür vorgesehenen Platz in dem Gehäuse.

It is not a good idea to put fast SSDs into the optibay. System tries to negotiate at 6 Gbit, but it fails; disk is recognized but it couldn't even be formatted. I've waisted a lot of time to find a reason. After swapping SSD with original mac's HD both work properly, one at 6, another at 3 Gbit

Good to know, thanks!

No problems here with a Samsung EVO in the optical bay. Only downside that is not really fast (80-90 mb/s) but amazing performances on booting time, shut off and opening programs.

Mike - Antwort

I have to withdraw my comment. It is NOT a good idea to put a SATAIII SSD in the optical bay. It gives random freezes. Swapping it with a HD is indeed better. Better read/writes too. Only downside is that SMS won't work on the optical bay so treat your baby with care. Also Sleep issues might occur when placing a HD in the optical bay (a total freezing system). I already wasted a HD that was in the optical bay.

Mike - Antwort

I've replaced the optibay with a samsung 840 pro but can't format it nor copy files (a few files work) to it. Do you suggest putting the HDD in the optibay instead? Did you clone the HDD to the SSD before swapping them? Will my Mac boot from the HDD the first time I boot even though it's in the optibay? I would really appreciate an answer, I've spent too many hours trying to figure it out!

Carl - Antwort

Also had this same problem. Tried and failed a Samsung firmware upgrade. Ended up send drive back to Amazon.

Andrew -

Okay it seems like some models of MacBook Pro have issues with a fast (6Gbit/s) SSD in the optical bay. Even though my Mac says it offers 6Gbit on both bays it simply didn't work in the optical bay. So I switched places between the two drives and everything seems to work. My Mac booted from the old HDD in optical bay automatically and then I cloned it afterwards and changed the startup disk to the new one. As said before, don't put a fast SSD in the optical bay!

Carl - Antwort

Hello Carl. What have you done after switching places between the two drives? Can you explain it with more details please? I have the HDD in the hard drive place, and an SSD in the optibay, and I have a lot of freeze / beachball. Thanks.

danielsam55 -

I'm on a Macbook pro 13" Late 2011.

danielsam55 -

I have the startup set to the SSD in the optibay.

danielsam55 -

I've already done it. switch the hard drives and reboot, that's all. Working without beachballs XD

danielsam55 -

My understanding is that SSDs will work (at 6Gbps) in the optical bay of late-2011 13" MBP models but not in late-2011 15" or 17" models and not in earlier 13" models. Are those of you reporting problems installing on late-2011 13" models (MD313LL/A [2.4Ghz] or MD314LL/A [2.8 GHz])?

Steve - Antwort

I'm experiencing the same issues with the HDDs in the optical bay. I've tried multiple drives (WD caviar blue 3G and a Seagate 6G) with no luck thus far. I replaced the SATA cable and that didn't help with either drive. My SSD still works fine in the main bay but I would like the extra storage.

For those of you who got the HDD in the optical bay working, which HDD (brand and model) did you use?

My MBP is a Late 2011 15" (8.2)

woestmab - Antwort

My understanding is that SSD in the optibay for 2011 MBPs will only work on the late-2011 13" model (not the 15" or 17"). I can confirm that it works in my late-2011 13" MBP. I have a Samsung EVO 500GB in my optibay (HGST 1TB in the hard drive bay) with no problems at all: negotiated link speed of 6Gbits for both drives and not beach balls or other slowdowns.

Steve -

I'm not trying to put an SSD in the optical bay. As I said, I've tried multiple HDDs but none of them seem to work. I know that it's possible to put an HDD in the optical bay because I bought the computer with one in it but it seems that none are recognized. I have tried multiple brands and speeds with no luck. I would like to know which specific model of HDD works in the late 2011 15" optical bay.


woestmab -

Many people have this problem and they all had the 2011 MBP model. The SATA controllers are both 6Gb/s on optic drive and HDD from 2012 (mid 2012 anyway). And of course we're talking about the non-retina. The last non-retina came out mid 2012.

Make sure you have removed the 2 screws at the end of your super driver unit and move it to your NewHD bay with the metal piece eye loop.

Kamiiyu - Antwort

Normally with the HD enclosure there come a set of screws. use these to screw down the HD in the enclosure since you need to flip it up side down to reinstall it into the MBP

Bart - Antwort

Here they picture Crucial as their choice, you can also find some great options at Samsung (it is what I installed and it works just as good if not better than the crucial I installed in my wife's iMac. here is their site http://www.samsung.com/us/computer/solid...

Its just another great option. Also when installing SSDs make sure to enable TRIM support (crashes can and probably will occur if you don't) TRIM enabler is available free and the pro version is $10 http://www.cindori.org/software/trimenab... It is the easiest solution for this issue.

  • Verwende zwei #1 Kreuzschlitzschrauben, um die Festplatte im Gehäuse zu sichern.

Replaced the optical with hdd, as well as replaced the hard drive with an ssd. Now I get the circle with a line through it. But, when I hold the option key down, it gives me both hard drives, PLUS, the thumb drive I have in the USB port with a Mountain Lion installer. It even shows the recovery disks, but gives me the circle with the line when I choose one. Any help is appreciated.

My mbp shipped with OS 10.8, and I had upgraded twice to 10.10

I've a 10.7 USB which upgraded my old MBP.

My plan today was to boot with my new ssd, my time machine back up and the Lion usb plugged in.

I would then click on the Lion usb, and tell it to put the OS and time machine back up on the ssd.

So I help down ALT and when it started it gave me the options of the usual Mac internal or the Lion USB.

I clicked Lion, but instead of taking me to the install options (Disk utility, restore from time machine etc etc) it gave me that grey circle with a diagonal line through it. The no entry sign - grey on grey - that I think you have.

Some googling said that it is because I was trying to usb a 10.7 install on a MBP that shipped 10.8

You can't go back, apparently.

So if any of the OSs are older than the mac you got, you will get this error. The grey in grey no entry.

I just cloned my HDD to my ssd (Carbon copy cloner free 30 day trial) using an external stat-usb3 wire and all is good.

I have a 17" Macbook Pro6,1 unibody with an Intel Core i5, 2.53GHz. I was successful installing a 250GB SSD in the DVD bay, and I'm able to boot from it. I did this by first installing OS X 10.9.4 on the SSD mounted into an external HD case, testing the system to see if it would boot up into the SSD, then installing the SSD and carrier in the DVD drive bay. The system now boots up from the SSD with no problems. If you are having installation problems, I recommend trying this method.

roger hall - Antwort

This is really for step 23: reassembly

You can not get the orginal screws back in to hold the new optical drive replacement in place because there is a black plastic filler running along the front edge of the part. There is no place for the screw head to go. I had to remove some of the plastic to get the machine reassembled. Whoever tested this overlooked what I think is a major problem. How many macbook pros are out there with only one (maybe two if you're lucky) screw holding this thing in place?

I got extra screws and have no idea why. The bits included in the kit are poor and don't work on most of the screws. I had to use my own tools instead.

I'm using a 13' MBP mid 2010 and I just swapped my HDD for a SSD. Al works perfectly fine!

So i bought the unibody laptop dual drive (from iFixit) and replaced the optical drive for the original HDD from my MBP. The installation with this guide went perfectly, however, the HDD is not recognized in disk utility.

I put the old HDD back on the original HDD bay, the HDD boots and works. I placed back the optical drive in the optical bay, also works. But when i put the HDD in the unibody laptop dual drive (iFixit), it is not recognized via the USB-port(however, the HDD starts spinning) or when installed in the optical bay.

So i think there is a software issue where my MBP does not recognize a HDD in the optical bay. Is there a way to force the OS to look for storage/HDD via the optical bay STATA cable?

All help is welcome!

Same here: installed original hdd in optical bay and it won't mount. Tried it using the sata cable on different computer, and the drive spins, but doesn't mount either. Would love to get a fix (or at least an explanation) for this. The whole point was to add extra storage, but so far, no dice.

Simon Abrams -

Did you ever find a solution?

I installed mine, but the ssd I'm using was a bootable usb running Yosemite, and now that I plugged it in, I'm getting a circle with the slash through it when I try to boot to it, and I can't unmount it or reformat it from the recovery Disk Utility or in Mountain Lion on the stock hdd still inside.

drguttridge -

Same issue here unfortunately... new SSD in primary slot is recognized fine and allowed me to install OS X with no issues from USB. However, both during the install when booting from USB and post-install within the full El Capitan OS, I simply do not see any '2nd' hard drive in the system - for the record I just reused the same 500GB HDD that came with my MBP; and I ran the exhaustive System Profiler tests prior to doing any work to ensure I'd have no HW issues/surprises. Sure enough,. I can hear the mechanical drive churning as the power runs to it, so I know it's hooked up okay. For some reason the drive just isn't being recognized by the Mac OS. Hoping someone can help me resolve this so I don't feel bad about spending the [extra] money on the iFixit enclosure system vs. one of the cheaper alternatives I found online, sigh... Any help would be much appreciated, thanks!

Brian M -

Figured I'd reply to my own message just above for those interested or following my situation. The 'churning' I heard was actually the left fan inside the system, which I managed to disassemble so I could lubricate the sleeve bearing with a touch of mineral oil - now it's as quiet as ever and works great. Also, I ordered a replacement optical SATA adapter cable from iFixit and this resolved my issue of accessing the hard drive moved to the optical slot inside the dual drive enclosure. Long story short - all of my issues are resolved thanks to some disassembly/repair work and new parts from iFixit!

Brian M -

Same problem happens, i don’t know how to fix that as well. Anyone has any idea? Thanks

I just have finished installing second SSD to my MBP (unibody 15` 2010).

First one was changed like one year ago. Samsung 500GB SSD. It is in my HDD bay and I'm running system from it.

Today I put a new Samsung 1TB 850 Evo 1 SSD in to my optic bay.

I encounter problem with SSD not recognized by Finder.

But It was recognized by Disk Utility.

What I did was I erase new SSD by Disk Utility. Then the new partition was created and now It has been seen by Finder.

So If you see it in Disk Utility just erased it.

Some extra info in under this link--> https://discussions.apple.com/docs/DOC-4...

Wish you all luck :)

Hi all,

I did this and all seemed to be working fine, both drives showed up and all was good then about 20 minutes later i got a message saying that "the drive had been ejected incorrectly" or something like that. The drives have now disappeared from finder and Disk Utility. I took the SSD out of the superdrive caddy and put it in an external USB3 caddy, it's working fine. I even left this connected over night (all OK). This morning i put the SSD back into my Late 2011 MacBook and the same thing happened, 20ish minutes and then the eject message... Have i missed something?

Any help would be very much appreciated.

Dear iFixit

I changed my Hdd with an ssd using this guide. My hdd is now in a caddy where the optical drive used to be.

I can see my original drive ( Toshiba 500GB ) in the disk utility-app, but i can't reach my data on it.

When i take it out of the caddy again and put it in a external Hdd case, i can read it perfectly fine.

So there is nothing wrong with the hdd or the connection.

Is this a problem i can fix with software?

Thx for the help!

Great guide, thank you! Took me 40 minutes to complete. I also cleaned my cooler fan though as i regularly do. I have moderate experience, Took apart my macbook (and other stuff too) several times. Not doing this daily though. Everyone can do this when keeping the basic rules in mind: Take your time and space and use quality tools.
