    • 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.

    • The access door should now be raised enough to lift it up and out of the Unibody.

    • Be sure the access door release latch is vertical before proceeding.

    • Grab the white plastic tab and pull the battery up and out of the Unibody.

    Great tutorial ! great step !

    Even though it’s specifically stated, you have to make sure the access door latch is vertical or the battery won’t be removable.

  4. MacBook Unibody Model A1278 Subwoofer & Right Speaker Replacement, Lower Case: paso 4, imagen 1 de 1
    • 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 - Contestar

    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 - Contestar

    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 - Contestar

    I used the Phillips #00 tip from my Pro Tech Toolkit, and it worked well enough. But yes, maybe #000 might have been better on the lower row of screws. Note to myself: Always read the comments first.

    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.

    I followed my usual process of putting in all the screws loosely, then tightening them gradually in distributed pattern, to help ensure that the panel settles in place evenly. But maybe some orders are better.

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

    Thanks for the guide!

    It's implicit in the two photos, but worth mentioning because it blocked my progress in this step for a bit: You have to put the release latch back into its horizontal, closed position before you can lift off the lower-case panel.

  6. MacBook Unibody Model A1278 Subwoofer & Right Speaker Replacement, Optical Drive: paso 6, imagen 1 de 1
    • 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).

    petterwolff - Contestar

    DO NOT REMOVE THE SUBWOOFER CONNECTION. Step 6 IS NOT NESCESSARY.

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

    kenneth rhem - Contestar

    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.

    todd - Contestar

    Oops, I followed Step-6 and my subwoofer connector came off from the motherboard!!! Please suggest me what needs to be done now?

    Srinivasan - Contestar

    Happened the same to me ... step 6 is a @%#$$. You should put now a way to repair the damage done. I just have four small tin marks on the board ...

    stratorick - Contestar

    Happened the same problem to me ... step 6 is a @%#$$**%%#. You should put now a way to repair the damage done. I just have four small tin marks on the board ... and looking to sky for help

    Badruddin Hisbani - Contestar

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

    Bill Cole - Contestar

    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.

    • 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.

    Ismael Neiva - Contestar

    Bonjour J’ai eu le malheur de toucher à ce câble et depuis je n’ai plus de retro-éclairage sur mon écran. Est-ce lié ?

    Hello I had the misfortune to touch this cable and since then I have no more backlight on my screen. Is it related? (but the computer works fine when I plug in a screen)

    • Use a spudger to pry the optical drive connector straight up off the logic board.

  9. MacBook Unibody Model A1278 Subwoofer & Right Speaker Replacement: paso 9, imagen 1 de 1
    • Remove the two Phillips screws securing the subwoofer to the upper case.

    • The longer of the two screws is on the right.

    Longer screw was on the Left for me.

    amiller770 - Contestar

    Left: 3.7 mm

    Right: 4.0 mm

    As I measured with a vernier caliper.

    • The subwoofer is still connected to the right speaker, so don't completely remove it just yet.

    • Lift the subwoofer off the optical drive, and set it above the computer.

  11. MacBook Unibody Model A1278 Subwoofer & Right Speaker Replacement: paso 11, imagen 1 de 1
    • Remove the two Phillips screws securing the camera cable bracket to the upper case.

    • The leftmost screw may remain captive in the camera cable.

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

    mcbohdo - Contestar

    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.

    Bill Cole - Contestar

  12. MacBook Unibody Model A1278 Subwoofer & Right Speaker Replacement: paso 12, imagen 1 de 1
    • 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.

    • Lift the optical drive from its right edge and pull it out of the computer.

    • The hard drive cable may become disconnected from the logic board when removing the optical drive. Ensure it is connected during reassembly.

    • Peel back the small piece of black tape covering the right speaker cable.

    • Use the tip of a spudger to pry the right speaker up off the adhesive securing it to the upper case.

    • Lift the subwoofer and right speaker assembly out of the upper case.

    Note that the subwoofer case has 3prongs through which the camera cable is threaded. Remember to re-thread that cable through the prongs when re-assembling.

Conclusión

To reassemble your device, follow these instructions in reverse order.

I have a Macbook Pro 13, mid-2009, A1278 and the speaker broke it.

Can I put a speaker A1278 a macbook pro 13 mid-2012?

All speakers A1278 model work in any model of Macbook Pro A1278, regardless of the year?

Mrgustavo - Contestar

I have good sound again, thanks.

2008 MacBook (aluminum).

The hardest part was starting the optical drives hold down screws, my jewelers screwdriver maginetic tip is weak.

Total time was about a half hour.

kqc7011huts - Contestar

If all you have are Phillips screwdrivers, be very careful with the screws at the split of the bottom case and all of the internal ones. You may have to drop to a Phillips #000 if you don’t have a JIS #00, which appears to be the correct tool for them, based on the actual fit of the bits in my (iFixit) set.

Bill Cole - Contestar

Hi guys, does anyone know if the subwoofer spare part is the same for the model A1278 from late 2008 and 2009 and so on? thanks in advance

Micro - Contestar

I bought the speakers in Ali express for less than 9 € and my late 2008 MacBook unibody sounds well again. Thanks for your help.

Antonio Alvarez - Contestar

Great instructions except for Step 6: CAUTION!! 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, comments state that you can pull back foam padding on the connector and remove the red and black wires to disconnect. You will need to reinsert the wires from new speaker to reconnect.

If you are not replacing the subwoofer and only need to remove the optical drive you DO NOT need to release the subwoofer connector shown in this step.
