Qué necesitas

  1. Reemplazo del disco óptico del MacBook Unibody Modelo A1278, Puerta de acceso: paso 1, imagen 1 de 1
    • Con la carcasa cerrada, coloca el Unibody con la parte superior hacia abajo sobre una superficie plana.

    • Presiona el lado ranurado de la pestaña de apertura de la puerta de acceso, lo suficiente como para poder agarrar el extremo libre. Levanta la pestaña de apertura hasta que quede 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.

    • Antes de seguir, asegúrate de que la pestaña de apertura de la tapa de acceso esté vertical.

    • Sujeta la pestaña de plástico blanco y extrae la batería del 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. Reemplazo del disco óptico del MacBook Unibody Modelo A1278, Carcasa inferior: paso 4, imagen 1 de 1
    • Retira los siguientes ocho tornillos que aseguran la carcasa inferior al chasis:

    • Un tornillo Phillips de 3 mm.

    • Tres tornillos Phillips de 13.5 mm.

    • Cuatro tornillos Phillips de 3.5 mm.

    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.

    Les Kitchen -

    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.

    facebook - Contestar

    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.

    • Usando ambas manos, levanta y retira la carcasa inferior de la carcasa superior.

    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. Reemplazo del disco óptico del MacBook Unibody Modelo A1278, Disco óptico: paso 6, imagen 1 de 1
    • Usando el extremo plano de un spudger, levanta el conector del subwoofer de la placa lógica.

    • En algunos modelos, el conector del subwoofer está soldado a la placa lógica y se romperá si haces palanca. Si necesitas reemplazar el altavoz/subwoofer, puedes tirar hacia atrás del relleno de espuma del conector y retirar los cables rojo y negro para desconectarlo. Vuelve a introducir los cables del nuevo altavoz para volver a conectarlo.

    • Si sólo vas a desmontar el disco óptico y no vas a sustituir el altavoz/subwoofer, no es necesario que desconectes este conector.

    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.

    • Desconecta el cable de la cámara tirando del extremo macho hacia fuera de su conector.

    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)

    Longer screw was on the Left for me.

    Left: 3.7 mm

    Right: 4.0 mm

    As I measured with a vernier caliper.

    • El subwoofer sigue conectado al altavoz derecho, así que no lo quites del todo todavía.

    • Levanta el subwoofer del disco óptico y colócalo encima del ordenador.

  11. Reemplazo del disco óptico del MacBook Unibody Modelo A1278: paso 11, imagen 1 de 1
    • Retira los dos tornillos Phillips que sujetan el soporte del cable de la cámara a la carcasa superior.

    • El tornillo situado más a la izquierda puede permanecer cautivo en el cable de la cámara.

    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. Reemplazo del disco óptico del MacBook Unibody Modelo A1278: paso 12, imagen 1 de 1
    • Retira los tres tornillos Phillips de 2,5 mm que sujetan el disco óptico a la carcasa superior.

    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.

    Henry Kim - Contestar

  13. Reemplazo del disco óptico del MacBook Unibody Modelo A1278: paso 13, imagen 1 de 1
    • Levanta el disco óptico por su borde derecho y sácalo del ordenador.

  14. Reemplazo del disco óptico del MacBook Unibody Modelo A1278, Disco óptico: paso 14, imagen 1 de 1
    • Retira el cable de la unidad óptica tirando de él en línea recta para separarlo de la unidad óptica.

    • Este conector es especialmente profundo, así que asegúrate de separarlo de la unidad por el centro del conector.

I ruined my laptop because of this guide.

The step 6 says it's a connector that comes of (sub-woofer), mine was welded, I broke it, I cannot fix it.

i am frustrated, and I know I should only blame myself for following blindly that guide.

But at least I thought I should let people know : be careful when removing that sub-woofer connector!!!

Thomas C - Contestar

I also broke the sub-woofer connector away from the board, the connection to the board is very fragile, however I managed to solder the connector back on with a very fine soldering iron, (tricky). but it worked. I don't think it is really necessary to disconnect the sub-woofer cable to remove the optical drive, I'll find out when I get a new one to replace the old broken one. To remove the subwoofer cable it would be necessary to hold the connector in place while the plug is very carefully prized up from the lead side without moving the connector socket.

John Chinnery - Contestar

Completed this one successfully. Now running OCZ 256 GB SSD in main bay and WD Black 320GB in optical bay.

Daniel Reyes - Contestar

PLEASE change Step 6 to not blindly pop the subwoofer cable off of the logic board. I also have broken this connection by following the instructions. The comments do not print out/are not shown on the pdf! Some people (like me) may never see these comments until too late.

Jonny - Contestar

My computer had a different optical drive than shown. Instead of the screws going through the body of the drive, it was secured by two screws at the corners opposite the screw by the connectors (i.e, along the wall where the CD slot is). In addition, in order to repair the drive, black tape sealing the unit had to be peeled back in order to open it (and the screws underneath the tape were placed slightly differently).

italtrav - Contestar

Fixed my optical drive my Mac book runs great

victor generalao - Contestar

Just a small tip: I wanted to replace my optical drive that I took from my older MB (A1181) with the broken optical drive in my newer-but still old- MB (A1278). But the drives aren't the same. The connectors don't fit and you can't replace them. So don't try to do this, if you planned to do it.

mofo - Contestar

I broke the connector, too. Thanks to this guide. why don't they change the step 6?
