    Step 1 (technically step 9 - replacing the base plate) Apparently one of my screws was a micron or two smaller than the others. This screw belongs to the hole above the optical drive, which is also apparently a couple of microns smaller than the others. It took seven attempts to figure which screw had originally been in that hole; all the other screws were too large, but fitted perfectly everywhere else.

    Bizarre much?

    It might be a matter of how the screws are driven in, and not that they're slightly different sizes. When I reassembled my MacBook, a couple of the screws, including the one over the optical drive you mention, were hard to drive in and jutted up a little bit instead of sitting entirely flush. Swapping screws didn't help. The solution was to unscrew them and drive them in at a bit of an angle - perpendicular to the slightly curved surface of the back plate where the screw holes were, instead of fully vertical with respect to the ground the Macbook is sitting on. Doing it that way, the screws were easier to drive in and they all ended up flush in their holes. Didn't matter which screws they were. (I swapped a few around just to check after reading this.)

    Andrew Janke -

    I had no such screw issues. Either there are differences in manufacturing lots or I just got incredibly lucky during reassembly!

    xtophr -

    I discovered a great way of organizing the screws. I used an ice cube tray and added the screws in order, keeping the different kinds together. So when it came to reversing the steps, the screw order was an added control step to returning everything in its place.

    Great advise! Love it! :)

    Ririds -

    I used to do that and that worked really great until I bumped it by accident and the entire tray went on the rug! I spent the next day sorting things out.

    Now I use these:


    The lower ones 50 to a package. I mark them w/ blue tape. Often if it's part like the fans, or the optical drive I'll tape the screws into/near the holes where they belong. I did this a lot especially w/ the bottom screws from MBPs until I'd done so many I knew exactly where the longer ones went.

    Richard Sato -

    I wrapped the screws in a piece of blue masking tape and wrote the number on the little pouch I made. Then I stuck the blue tape pouches on the underside of the case bottom in order.

    Roscoe -

    I take double-sided tape, put that on a piece of paper, stick the crews to that, and label them.

    Best I've found is a bead sorting tray. They're like $5 at Wal-Mart and they have a lid that seals up and won't let them jump between containers.

    maccentric -

    I take a sheet of paper, pierce the screws through the paper, take a pen and box the screws and write out what step they belong to.

    Nils -

    @Will, in my case I had the same result as you did. As a reminder to myself the next time I need to open the computer, I put a dot of white paint on those two screw's head and a very, very thin ring of white on the very edge of each hole, that way I'll know they go into those two holes.

    Roger - 回复

    Actually the four screws on the bottom were not threaded all the way up. I didn't check to see if the thread gauge was the same on them, but it wasn't until I had about four screws out (I didn't take them out in the order that the bottom all came out first) that I noticed a difference. I then took out the rest of the bottom ones to see if they matched the two that were already out that weren't threaded to the top. They did. So I went under the assumption that those were all bottom screws and when I put it back together everything went fine with no resistance.

    So there are three types of screws: Four for the bottom, three long ones as indicated and three others that might be slightly smaller than the bottom ones.

    Although its more than a year since your contribution, I thought you might be amused to know that it is not just that the screws go in more easily when at an angle, Apple actually drilled and tapped the holes at a 15% angle. I too had tried to drive them in straight. An Apple "genius" - I was in for something else - clarified the design for me. It was done so that the screws lay flush on the angled part of the lower case. Nice design, but since Apple encourages DIY memory and drive changes, they could have mentioned this little ... trap.

    Hey everyone, here's the very best way to PERFECTLY organize your screws AND keep track of the order of the procedure: Get a piece of plain corrugated cardboard and a pen (I like using a Sharpie). For EACH step of the disassembly, draw a simple diagram of the layout of the computer on the piece of cardboard, with dots or Xs where the screws are located. Right after you remove each screw from the computer, poke a hole in the cardboard in its corresponding diagram position with your screwdriver and place the screw in that hole. If there are other non-screw related parts to be removed, you can add notes below each step diagram to remind you of where they go or how they should be placed. This cardboard method is great not only because your screws will not go flying or get mixed up by accident if bumped, but each screw goes EXACTLY back where it came from and you can keep the cardboard as a template for future use if necessary!

    During re-assembling (put the screws back in), it is important to note that the 3mm threaded holes are not completely vertical, but bent a little bit such that the hole direction is rectangular to the tapered surface. The force of the screwdriver must point towards the direction of the hole. Otherwise the screw gets jammed

    1- no T6 screwdriver- was careful using needle nose players to loosen 2 screws protruding up, then use a small phillips to push real hard into the T6 slots, SLOWLY turn , also used a small flat head screwdriver (for eye glass repair) was able to grab thread on T6's, made a small mark with screw driver across the top so I could see when it started to turn.

    2- no spudger -made one; cut a little strip 1/2" x 1 1/2" of plastic. couldn't get it to slide under plug, there's an edge where plug fits. so lifted old fan out, pulled upward on the plug it popped right out with very little effort. I used my home made spudger to push the new plug into place.

I had just installed a new OS and the kernel_task went going nuts, using 90% of the CPU. Hours on the phone with Apple did not resolve the issue. On a whim, I put the old battery back in and Voila!

    This laptop definitely originally shipped with Phillips screws—but, Apple has been known to replace Phillips screws with pentalobes when one of their devices is brought in for service. Sorry for the rude surprise! Fortunately the correct driver is easy to find nowadays. [Blatant self-promotion alert!] If you support free repair manuals, consider picking one up from iFixit. Good luck!

    Jeff Suovanen -

    Me, too, and it’s plausible that this machine has been serviced by Apple in the past, replacing the screws as Jeff Suovanen suggests.

    iFixit shipped a pentalobe bit with the kit, but it’s too large for the actual screws, so it looks like I now need to get another bit. But what size?

    Jeff’s link is to a driver with a P5 bit, and that page links to a P2 screwdriver, but since I don’t know what size I actually need (and I don’t have a micrometer to hand) I’m reluctant to buy two on spec.

    Norman Gray -

    To keep track of screws, I used the suggestions above by taping a photo of the lower case to a piece of corrugated cardboard and inserting/taping the screws in place. Also, as some have noted, the screws go back in at a slight angle; they are angled toward the center of the unit.

    If your vision, like mine, is getting too fuzzy to be able to distinguish between a tiny Phillips screwdriver and a tiny Tri screwdriver, there’s an easy way. With a Phillips (or a Pozidrive) you can get two opposite wings to reflect the light from a lamp or window straight towards your eye at the same time. With a Tri (or Penta) you can only get one wing to reflect at a time, however much you twiddle it.

    Alan Waller - 回复

    There’s a very easy way to avoid cross-threading a screw thread, any size.

    Put the screw into its hole and start by turning it gently, slowly BACKWARDS. When you hear a little “Click!” sound, the male thread has just passed the opening in the female thread and is in exactly the right position to enter into it correctly when you start to turn in the correct forward direction.

    Remember, all drivers except hex (Allen key) and TorX need pressure to avoid slipping out and damaging the head. So even when you want to turn it in with LOW moment/torque, keep the CONTACT PRESSURE high.

    Alan Waller - 回复

    The keep the pressure on is on point. In my case once I loosened my first screw I thought I could relief my initial pressure. It was a mistake. I was doing the whole thing very slowly as a precaution. That helped me notice that the Phillips screw driver was sliding up out of the screw head. Not being sure why, I put pressure back on the screw driver until almost all the screw was out of the hole. Once out, I examined closely to find out that the threads have some sort of coating. It looks to me like some kind of locktite. Then I understood the importance of keeping the pressure on all the way through. It made me uneasy having to keep so much pressure on such tiny screws, but I found it was the only way to prevent damage to the “slots” on the heads. Anyway, all of them suffered some degree of damage, but I was able to successfully remove them and reinstall all of them back in their original holes.

    After reading this page on iFixit several times, I just could not face all the work of replacing the Logic Boards on two MacBookPro 2011s even if I was prepared to pay approx 400 USD (which I wasn’t). Then I read the reviews of a couple of folks who’d stripped down their machines and put their logic boards in the oven and, it worked! I wondered, if I just used my new Steinel Hot Air Tool (heat gun in my language) recently delivered from iFixit, on the logic board in-situ, without removing it? So I removed the battery, hard drive, and RAM and unplugged all the leads I could see WITHOUT removing anything else physically. Then using the 500 degrees set on the gun (setting 2) I ‘played’ the gun over the logic board for about 60 seconds on machine one with the restart problem (plus latterly, not completing start-up). Long story short… it worked! I spent a long time getting the s/w to load, but the commentary is too short to let me relate that part… ping me if I can help you do the same! blackaye@gmail.com

    At first sight I was confused when I read the description at this step, 'cause it seemed that disconnecting the battery connector was optional, in order to eliminate static discharge. While it's a helpful advice in other circumstances (as mentioned as an example changing hard drives), when changing the battery it is not an option - you have to disconnect the battery connector.

    It would have been better to mention the optional disconnecting recommendation in a side-note.

    Other than that, an excellent guide!

    the fact that this step is optional can not be stressed enough. i tried disconnecting the battery and in the process it short circuited which now leaves me with an even more expensive problem than i had before when i just wanted to change hard drives (at least the new hard drive works fine..)

    the hard drive changing worked though.

    So - I have a weird comment about this. I wanted to make sure that I was getting the right model - so I opened up my laptop and then thought "well, why not just remove the battery while i'm in here, it's shot anyway". Though, I forgot about the stupid screws (Apple really did us over on that one!). Though I disconnected the battery connector and didn't bother to re-connect it when I was finished and just put the cover back on.

    Here's the weird part - when I went to turn my laptop back on...MY BATTERY WAS RECOGNIZED...AND WORKING! I was under the impression that the connector "connects" the battery's charge to the laptop, but this just doesn't make sense! Plus, now my very dead battery is in "normal" condition according to the system report. I haven't worked for apple, but have about 5 years of IT experience and am baffled by this! I'm starting to think i've experience a miracle! Has this happened to anyone else?

    You might be referring to the four pin section that would be used for jumpers.

    If you want to install OSX on it, this is what I've done (without a USB or bootable drive). First, if you're replacing the hard drive with the SSD (for example), then you just need to plug in the harddrive you replaced and boot it up via USB. Format the new hard drive you installed as a Mac OS Journal (eg: a drive that Mac understands it can install an OS on). Then, restart the computer, press CMD+OPT+R to start up the internet recovery off of the USB-attached hard drive, which will allow you to install a copy of Lion or Mavericks or Yosemite (depends on what was on your old hard drive) to the new one within the computer.

    So far, It's installing and it seems to be doing amazingly well.

Hi, Im going to replace my mac hard drive. Looking at this guide it seems that I wont have too much difficulty in doing so, but do i need to format the new hard drive before I replace the old one? or can I just replace it and then format it when I boot it up for the first time?

U don't need to format the hdd before you replace it with the ssd

I have the MacBook Pro mid-2012 15" and I have installed Samsung SSD 840 EVO 2.5" form factor drive and it fits fine. Really makes the MacBook fast.

I just measured the SSD thickness of a Samsung 850 EVO and it is 7mm. The Samsung spec sheet didn't have that info, it just said it was a 2.5" form factor. BTW, I also removed the DVD drive and installed another SSD as well. OWC has a good drive adapter to do this, called DataDoubler.

Following this excellent guide, I had my hard drive out in just minutes.

In terms of the practical hard drive swap itself, this guide was perfect, and it took 5 minutes. I didn't know though, that I had to partition my new hard drive before I could install new OSx. Found the info elsewhere, but would be useful to have it on this guide. Thanks

What is the best way to get all my data from the old hd to the new ssd?

Aaron Moore - 回复

1. Install new (blank) hard drive in external enclosure. 2. Use Carbon Copy Cloner to literally clone your internal HD to the new drive. 3. Install new drive.

Thanks for the great info. I have a mid 2012 15" non-retina macbook pro (non-SSD). Its specs are 2.3 GHz Intel Core i7, RAM 8GB, Graphics 1GB. Do you think if I upgrade to a SSD my mac would be able to run Adobe premiere pro, after effects, FCPX and photoshop better. Some apps crash at times and it really slows down if I try to edit 1080 videos. I mainly do weddings, so the projects are not that small. Thanks again.

That made me think of a more straightforward way of installing a new hard drive in my MacBook Pro.

Right now I boot from an external ( 1 TB ) USB drive, bootable copy made with SuperDuper!.

I intend to replace the internal drive ( 500 MB ) with un-formatted, fresh 1TB hard drive.

I wonder if, with the external drive connected, and after formatting the new drive, I could just use the SuperDuper to simply copy on the new installed drive?

Thoughts much appreciated,

No matter what you are working on, whenever the back is off of the computer, the first thing that should be done is disconnect the battery.

As long as the battery is connected, there is power going to the motherboard and if anything were to touch it while it is powered, you could easily cause several hundred dollars worth of damage. While the motherboard is powered up, there is always a danger of something rolling onto it, such as one of the screws you are removing while you're working on the hard drive. in fact, disconnecting the battery will still leave many of the motherboard components with a charge so great care should be taken not to touch the motherboard even when the battery is disconnected.

Electronic damage to a motherboard can be catastrophic and in many cases can cost more to repair than the computer worth. The battery should not be reconnected until you are ready to close the back of the computer.

If you are going to show how to replace the hard drive, Why would you have them remove the old hard drive without explaining to them that they should back up all of their important data first need to clone the information off of their old one first?

As far as I can tell, you have everybody removing the old hard drive without ever transferring their data.

Here is a link that explains in step one everything you need to do to before you start taking your computer apart

Easy to do upgrade my MacBook to an SSD took about 10 minutes. But then i was trying to reinstalling macOS and that took a long time cause i was transferring all the information off the old HDD

I purchased a 2.5” 1TB to replace the 250Gb storage only to find out that the 250Gb is a flash drive and there is NO way a standard optical drive will fit! As I had already formatted and copied all my files onto the new drive I could not return it to the supplier. A small consolation is that the 15” has 2 USB3 ports so I will be able to use it as an external without too much hassle.

This model uses a standard 2.5” laptop drive, as shown in the photos. If you have a Retina model then yes, it’s a whole different animal. ;)

What is the difference between the Samsung’s SSD 840 EVO 2.5 and SSD 850 EVO 2.5 ?

Charb Turbo - 回复

I am about to replace my Macbook Pro with an evo 2.5” ssd 860 1Tb. Still running on mountain lion. I am wondering which of these 2 ways would be easier or better:

1. Clone the whole existing disk (about 500gb) onto the new ssd. Replace the disk and then once it can boot up on the new ssd, update the OS to Sierra from mountain lion ( i can’t update to Mojave as i have an old Bamboo that wont work with it and Wacom is not making any new driver for it nor support it anymore! ) I am not sure if the apps will work after update of OS tho, coz they’re like all old apps like adobe cs6. and the old mac office.


2. Remove the old drive and put the new ssd in, and then do a fresh clean install of Sierra into the ssd. Then transfer all the files from the old disk and probably need to reinstall all the apps again.

Any recommendations on what would be the better thing to do ?

thanks so much !

@sleepycub Either method should work fine! I believe Apple recommends a fresh install of macOS, and then using Migration Assistant to transfer files, for the most stable result. So all things being equal, go with Option 2. Good luck!

Jeff Suovanen -

I have a question: Can you swap a MacOS SSD from a working mid-2012 MPB 13” to a MBP 15” of the same year period? Or you still need to format and then install OS?

I want to give my 13” laptop to my daughter and start using that of 15” with the premise of taking out the SSD and install it in the other machine.

Thanks in advance!!!

I would start by doing About this Mac and checking the model identifier in System Report. If they are the same (could be MacBookPro9,2 or MacBookPro9,1), your chances of a straight swap working are higher.

In general with different hardware spec you are safer doing a complete reinstall (you may be in luck if they are the exact same spec other than the screen size). Before you start, make a backup (I prefer Carbon Copy Cloner – it can make a full and bootable backup).

Put the SSD in the 15” and see if it works; if not, reformat and then use Migration Assistant to copy the backup onto the SSD once it’s set up for the newer Mac. This should work if you do a complete backup.

Thank you, Andrew Optimus Goldheart and team iFixit! just swapped in a 1TB Crucial MX500 SSD, as the OEM 1TB 5400 rpm HD was getting suspiciously flaky. went smoothly, with the exception of cloning the drive before swap. i kept getting an error saying that the SSD was disconnected (USB 3.0 -SATA case/interface bought on-line). i went through SuperDuper!, which was an absolute fail, as i couldnʻt find a way to restart the cloning without an erase first. Then i tried Acorns, but realized it had that demon .exe extension. finally got CarbonClone, which 1) decreased the frequency of disconnect errors, and 2) allowed me to pick up the cloning from where it left off (after scanning all the previously completed cloning). three days later, iʻm running on a SSD, with much relief.

Thanks I Fix It! I performed all the suggested mods and my computer works better than it ever did 8 years ago when it was brand new out of the box. I always assumed I bought a lemon. Now, it is the machine that I thought I wanted to own. Thanks for making it possible.

Can I replace it with a 1TB SSD?

dirtybirdie956 - 回复

Of course, I just replaced the 500GB SSD of a 15’’ 2012 MacBook Pro with a 1TB SSD (Samsung 860 QVO)

The best advice I can give to anyone who is going to do this is to have a complete set of all sizes of computer screwdrivers from ifixit. And order at least two sets of replacement screws and rubber feet from eBay which you can get for six dollars. Chances are you’re going to end up stripping at least one screw and losing some of them. You need to make sure that you put the right side screws in the right places and that they are all back in. That is the number one thing that can make this go south. Do not even attempt to do this if you were not sure that you have all of the potential tools that you might possibly need even if it’s Unlikely. And again, have a full set of replacement OEM screws on hand

Rob Anthony Dire - 回复

Thanks for the great guide.

Does someone know if there is a limit in capacity? I’m thinking of putting an 8TB Samsung 870 in my old MacBookPro9,2 … A Samsung 860 EVO with 4TB was no problem in the past.
