Use this guide to replace a broken AirPort/Bluetooth cable.

    • Remove the following ten screws:

    • Three 14.4 mm Phillips #00 screws

    • Three 3.5 mm Phillips #00 screws

    • Four 3.5 mm shouldered Phillips #00 screws

    • When replacing the small screws, align them perpendicular to the slight curvature of the case (they don't go straight down).

    How much weight can I save by removing the optical drive?

    You can save a lot of weight if lets say your installing a solid state drive or putting in a second hard drive but if you know that you use the CD/DVD disc drive a lot then you might just want to leave the drive alone.

    Tip: Use one of those weekday pill holders to have a cheep way to store screws you remove and each day of the week can be for different sizes or parts. It has been handy to have (much less expensive than the magnetic mat.

    Hello, where can I buy the screws I need in case I lose one of them?

    I have one stripped screw... How opening without drill it?! Any suggestions please?

    I also stripped a couple screws. I wasn’t able to open it up without drilling. After drilling the heads and removing the cover it was easy to hacksaw the tip and unscrew with a standard driver.

    My top tip - make sure you buy good quality Phillips screwdrivers and a magnetic holder. Cheap screwdrivers won’t get the screws undone safely. Without a magnetic holder you have no chance of getting the tiny crews in and out safely.

    A good Phillips 00 is your friend here. Also, when reinserting the screws, gently start anticlockwise and you wil feel a click at the start of the thread. This tells you you’re in the right place and less likely to cross-thread through force in the wrong place.

    I feel like these are 000 screws. Amazon sales describe them as such and my 000 screwdriver fits better

    Before ordering a new Trackpad remove the existing battery and try clicking the Trackpad. If it clicks OK with the battery out the source of problem is likely a swollen battery, which should to be replaced even if it still works to some degree. From the side of the battery you will likely see the soft part of the battery bulging beyond the hard case.

    That’s absolutely correct as I can testify. With the battery removed I also adjusted the T6 set screw that adjusts the sensitivity of the trackpad click, evidently someone had cranked mine down tighter than the factory setting.

    Le quatrième paragraphe dans les instructions en français n’est pas correct : ce ne sont pas les 2 petites vis, mais les 7 petites vis qui sont inclinées. Et les 3 grandes sont bien verticales.

    Tip: if you have a magnetic screw mat or similar, lay the macbook over the mat to make sure it catches any screws that may decide to fall of and hide under your table

    • Use your fingers to pry the lower case away from the body of the MacBook near the vent.

    • Remove the lower case.

    • Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board.

    • It is useful to pry upward on both short sides of the connector to "walk" it out of its socket. Be careful with the corners of the connectors, they can be easily broken off.

    Is this step of removing the battery connector required?

    manodh - Reply

    yes - as with disassembly of any electronic component you have to remove any power source. You don't want to accidentally turn the Mac on

    Prying the battery connector off does not take much force. I did exactly what the guide suggested (walked it off back and forth) with the spudger without any problems. Just be very gentle, much like with anything inside laptops, they are very fragile and need to be worked with carefully. A+ instructions, battery replacement was a success.

    Be patient on disconnecting this one. It worked for me step by step, little by little.

    I used the nails of thumb and pointer finger simultaneously - worked pretty fine

    • Bend the battery cable slightly away from its socket on the logic board so it does not accidentally connect itself while you work.

    I put some tape between the connector and socket while working on the drive.

    That's a good tip

    Anrothan -

    Great tip, I did that too

    One other note: The screw heads fit flush with the curvature of the case -- which means that they aren't exactly horizontal. In other words, they aren't perpendicular to the table that the computer is resting on. Don't try to force them straight in vertically, because you'll risk cross-threading them. (nearly ruined one screw hole myself!)

    On my MacBook Pro, the connector seems to be an integral part of the battery.

    I suspect it’s just like the special screwdriver required for seatbelts on cars – to discourage regular consumers from attempting repairs. Of course, this only encourages consumers to use the wrong tool to attempt to repairs

    • Use the flat end of a spudger to pry the AirPort/Bluetooth connector up from its socket on the logic board.

    I found that the connector itself is actually broken. I got stuck in the recipient side... I do not know how to fix that.

    Ivan Serrano - Reply

    I have the same issue! The AirPort/Bluetooth connector has separated from its cable and is stuck inside its socket on the logic board. I’ve tried pulling it out with tweezers, but there’s hardly anything to grab on to! Recommendations for solutions would be appreciated!

    Austin Reeves -

    N.B! Thank you very much all you here on iFixit! Some IMPORTANT notes. Be very careful BEFORE prying the connectors up and down. They are very fragile and the picture could actually be seen as showing a bending loading in their weakest direction, AROUND its slender axis. The connector is slender and inserted on the logic board, so the gentle "walking" up and down should be done ALONG their slender direction and WITHOUT touching the adjacent connectors. If bending is done around its axis the soldering comes apart and the cable is done and gone. Just happened. These flat cables are one of the weakest design spots in my experience. They are a major time, money and geist consuming reason for malfunction like Wi-Fi connection problems, HDD, SSD not found internally but externally from USB issues et al being found on different forums. Thanks again and again.

    Sadly, exactly the same problem here. The ribbon had already broken away from the connector at the logic board end when I opened up the back. The connector is stuck in its socket on the logic board. I tried walking it with the spudger, tried pulling (as far as I dared) with a tweezers, but it seems to be stuck fast. This is odd, because the other end, with the same kind of connector and socket, came out easily.

Had the most strange errors with a wi-fi with errors for long. Send the computer both to apple and to insurance without success.

Now I'm on my own on my wifi first broke saying "No hardware installed", Bluetooth was still working in the beginning thou. After checking here I ordered a new cable and everything was fixed in under 30 minutes.

The cable I bought was names -A in the end instead of -02 but everything works just fine so far. According to the seller they are the same. Thanks for help solving this strange problem in a simple way!

I've just made this and all my connectivity problems are now gone!

Thanks iFixit team :)

Fixed my wifi connectivity problems! However it did not fix my bluetooth connection. I did have a problem where the wire was actually disconnected from the actual connection and the connection was stuck in the socket. I got the connection out by using an Xacto blade on the side to pry it out. Then I followed all the other steps and it worked fine! I also disconnected the battery and had no problems reconnecting it.
