There are many benefits to adding a second hard drive to your laptop such as improved speeds, greater storage space, and less heartache when installing new software. Use this guide to install one using our optical bay hard drive enclosure.

  1. With the case closed, place the Unibody top-side down on a flat surface.
    • With the case closed, place the Unibody top-side down on a flat surface.

    • Depress the grooved side of the access door release latch enough to grab the free end. Lift the release latch until it is vertical.

    This is not a a1278 unibody MacBook Pro. A1278 MacBooks backs are one solid metal piece not two separate pieces. This guide is for a different MacBook Pro.

    This guide isn’t for a pro; it’s a MacBook unibody.

    So, it turns out that Apple used the model code A1278 for quite a few different Mac models, including both Pro and non-Pro versions! This guide is for the non-Pro Macbooks. There’s also one for the Pro models with the same A1278 identifier.

  4. Remove the following eight screws securing the lower case to the chassis:
    • Remove the following eight screws securing the lower case to the chassis:

    • One 3 mm Phillips screw.

    • Three 13.5 mm Phillips screws.

    • Four 3.5 mm Phillips screws.

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

    Jim - 답글

    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 - 답글

    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.

    Bill Cole - 답글

    When replacing these screws, the order to replace them in is as follows:

    1, Top left

    2. Top right

    3. Top center-left

    4. Top center-right

    5. Bottom center-right

    6. Bottom center-left

    7. Bottom right

    8. Bottom left

    I hope this information is helpful.

  5. Using both hands, lift and remove the lower case off the upper case.
    • Using both hands, lift and remove the lower case off the upper case.

  6. Using the flat end of a spudger, pry the subwoofer connector straight up off the logic board.
    • Using the flat end of a spudger, pry the subwoofer connector straight up off the logic board.

    • On some models, the subwoofer connector is soldered to the logic board and will break if you pry it off. If you need to replace the speaker/subwoofer, you can pull back the foam padding on the connector and remove the red and black wires to disconnect. You will need to reinsert the wires from the new speaker to reconnect.

    • If you are only removing the optical drive and not replacing the speaker/subwoofer, you do not need to disconnect this connector.

    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).

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

    Bill Cole - 답글

    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.

    Reading all of these comments prior to beginning the work, I didn’t even try to investigate the type of connector my laptop had. I just DIDN’T attempt removal of this connector, worked around it, and as others have mentioned, it is truly unnecessary to remove this connector. You can move the subwoofer (after removal of its other screws) out of the way just enough to slip out the old drive and slip in the new drive.

  7. Disconnect the camera cable by pulling the male end straight away from its socket.
    • Disconnect the camera cable by pulling the male end straight away from its socket.

    The lack of warning “Be careful not to pull up on the cable as you remove it from the socket.” here, as is displayed on a similar step on the “MacBook Unibody Model A1278 AirPort Card Replacement” guide, has caused me to break the cable. My WiFi is not working anymore. How can I replace only this cable? Thank you.

    mcbohdo - 답글

    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.

  12. Remove the three 2.5 mm Phillips screws securing the optical drive to the upper case.
    • Remove the three 2.5 mm Phillips screws securing the optical drive to the upper case.

    The lower left screw hole of the replacement drive purchased from iFixit doesn’t align with the screw hole of the body of the computer. Doesn’t seem to be a problem as the drive seems to be quite stable with the other 2 screws, and the “fit” within the drive area.

    is it 9,5mm or 12,7mm for the caddy? My stuff macbook pro mid 2010, need advice what size is compatible. Thank you

    Adi Purba - 답글

    All Macbooks use 9.5mm Optical Drive Caddy, also, If you’re wondering as well, the Optical Drive runs at SATA II speeds just like with the main hard drive area, so if you’re using a SSD, then it’s going to run at a slightly slower speed.

    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!

    It’s not wise to swop the optidrive for an HD as there is no physical protection. The caddy is only intended for an SSD.

    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.

    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 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.

    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.

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.
