I assume you have the newer model, with the built-in battery. It's still removable with tools, but these are the wrong instructions for that model.

Is there a manual to show, how disasembly the display, i mean, after step 5, to check the display between lcd and aluminiun back case?

On other guides you state the height of the HD that can be supported, e.g. MacBook Pro 15" Core 2 Duo Model A1211 Hard Drive Replacement , I have read ( but have not confirmed ) that the uni-body MacBook Pro can be fitted with the 750GB and 1TB 12mm drive from Western Digital.

Can you confirm this?

Many thanks in advance.

My display and aluminum casing has separated.

I don't know if it just snaps back together or does it need to be glued.

I dropped mine on the carpeted stairs and the display still works.

I'm hoping I can just snap it back together and that no plastic pieces or teeth of the snapping

portion have been broken........

When you say "left fan" is this "left when looking at the logic board after turning the computer over and looking it up opening it up" or "left when sitting at the computer keyboard and typing on it"?

We always use left and right in reference to the computer when you're using it.

Directions were great and the worn dc in board was replaced. The hardest part of the procedure is disconnecting the data display cable. A better description of step 21 is to slide the connector parallel to the circuit board towards the outside corner. Reconnecting correctly took several tries.

I used the tip of the spudger to nudge the corners a little at a time to seat the connector.

The ribbon connector for the keyboard has to be inserted all the way before seating the retaining cap. It took me three tries . First try power button did not work second try numbers keys did not work.

Thanks for the directions ...could not have done it with out them!!!

The fixit PH00 is the wrong screw driver for this entire job. It did not fit in the screws, it was too pointy and caused screws to be rounded off.

I have an late 08 macbook pro and replaced my cd drive with a hd caddy and hard drive put in it. everything works but my wifi is saying no hardware installed. Bluetooth and camera working just the wifi isn't. Everything was working just find before i did this but now i cant get my wifi back on.

Ian Ho - Reply

You have to be EXTREMELY careful when detaching and reattaching this cable!!! It carries your Bluetooth, iSight camera, and Wifi connections!! I was being very careful when reattaching it and ending up either messing up the connector on the logic board or the cable itself- both cases are equally as bad. The cable doesn't snap back in or have guides, and it is therefore difficult to know if it's in as far as it needs to be, etc. If you mess up the connector on the logic board (that's what it's connecting to), you have to replace the entire logic board, and if you mess up the cable itself (it has very small, delicate metal connectors), you have to replace your entire display!! Each costs around $500/ea! I did a ton of research before embarking on this procedure and really wish someone had made a note of this prior- learn from my mistake!

Evan Roth - Reply

I had some difficulty getting the 'isight' cable back on. Pay close attention when you remove it as you will need to reattach the cable at an angle to get the small protrusion on the right side of the connector passed the little black plastic block that is glued onto the system board. It looks like this little block is there to keep the cable from slipping out... so it makes it tricky getting it back in.

Andrew Gill - Reply

Personally I would avoid disconnecting the cable from the socket as advised in this step, one should be able to proceed simply by carefully lifting the cable free from the adhesive holding it on to the optical drive.

Like others here, I followed Step 6 as per the guide and ended up with no Bluetooth or iSight camera, due to somehow damaging the connector and/or socket, despite taking the utmost care. It is possible to carefully slip the old drive out, and a new drive in, with the cable connector in situ (at least that was the case on my Late 2008 MacBook Pro).

Trevor - Reply

You can remove the small smooth block that is blocking this plug pretty easy. Once you connect the plug then you can stick that block back in place, it's just glued down.

Melyn Vicente - Reply

I second what Trevor wrote: it's actually pretty easy to work around the cable without unplugging the connector and, as it's extremely delicate, I therefore recommend skipping this step.

Under the "specifications" tab, it says that they are M2.

The top screw was locked tight for me also and I eventually stripped the phillips screw head. The only thing I could do is drill it out. Since I replaced the optical drive with an SSD, I didn't need the screw after all.

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.

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

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 - Reply

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 - Reply

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 - Reply

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 - Reply

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.

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 - Reply

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 - Reply

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.

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.

Thanks

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.

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

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.

Mate,

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 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.

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.

Hi,

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!

Thanks,

Leon

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!

I followed the tutorial and everything works fine when I use an HDD 320 go but when I use the new HDD I bought which is an Hitachi 1T 7200T 2.5 P I have some trouble. The disk utily takes a long time to recognize the new hard drive and then starts not responding.

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.

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!

  • Don't ditch that drive! You can still use your optical drive externally with the help of our SATA Optical Drive USB Cable.

  • Align the cable's SATA connector with the drive's port and plug in securely.

  • Plug the USB connector into your laptop and your optical drive is ready for use.

There is a small metal button in the front of the drive and you can use that to eject the drive if you were wondering.
