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

  1. Remove the following ten screws:
    • 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?

    gunes314 - Contestar

    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.

    Robert Wacker - Contestar

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

    taylornya - Contestar

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

    rodrigosady - Contestar

    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.

    Michael Wilkens -

    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.

    jeremyyoung - Contestar

    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.

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

    • Remove the lower case.

  3. 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 - Contestar

    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

    khull -

    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.

    aekinaka - Contestar

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

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

    Stephen Smith - Contestar

    That's a good tip

    Anrothan -

    Great tip, I did that too

    Ahmed Mahran -

    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!)

    lelandjordon - Contestar

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

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

    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.

  6. Carefully pull the camera cable out of its socket on the logic board.
    • Carefully pull the camera cable out of its socket on the logic board.

    • Pull the cable parallel to the face of the logic board. Pulling it upward may damage the logic board or the cable itself.

    Be extremely careful on step 6 with late 2011 model unibody macbooks! The cable is connected very tightly to the board and has a great chance of ripping if you just pull the cable.

    Tim Rauls - Contestar

    My cable is broken, have the part number or code to buy?

    VÍCTOR RIFFO - Contestar

    I found there was plenty of length in the camera cable (as it goes around two sides of the optical drive) so does not need to be disconnected - just ease it out of the slot alongside the drive and lay it diagonally across.

  7. Carefully move the AirPort/Bluetooth ribbon cable out of the way as you peel the camera cable off the adhesive securing it to the subwoofer and the AirPort/Bluetooth bracket. De-route the camera cable out from under the retaining finger molded into the AirPort/Bluetooth bracket.

    • De-route the camera cable out from under the retaining finger molded into the AirPort/Bluetooth bracket.

    Take a few phone close-ups of this corner of your system prior to disassembly. Extra photos really help during reassembly.

  8. Use the tip of a spudger to pry the antenna connector closest to the logic board up from its socket on the AirPort/Bluetooth board. De-route the antenna cable from under the finger molded into the AirPort/Bluetooth bracket.
    • Use the tip of a spudger to pry the antenna connector closest to the logic board up from its socket on the AirPort/Bluetooth board.

    • De-route the antenna cable from under the finger molded into the AirPort/Bluetooth bracket.

  9. Using the method described in the last step, disconnect the remaining three antenna connectors. De-route their cables from the slots cut in the AirPort/Bluetooth bracket.
    • Using the method described in the last step, disconnect the remaining three antenna connectors.

    • De-route their cables from the slots cut in the AirPort/Bluetooth bracket.

    I found re-attaching these antennae connectors the trickiest bit by far as they appear very delicate and seating them correctly was fiddly. In the end lighting them from the side with a small torch helped to check their position before gently pushing them down. The first one made a clicking sound as it connected, the other two went on silently. MBP wifi working perfectly now. I’m fairly sure that was at least £100 of labour had I taken it in for repair so thanks ifixit for saving me money and for the warm glow of accomplishment!

    Andrew - Contestar

    Actually, on my repair attempt, one antenna cable broke (on the image the bottom right one in the red square), I’m not sure whether it broke already before or was morbid somehow. Fact is. suddenly I had this cable in my fingers, and was sure I completely broke the macbook and need to find a new display now.

    But as it turned out: the Mac is still fully working, including WIFI, BT, Camera etc. So apart from my huge relief, I want to address that these cables may break easily at their connection with the display. And that one antenna might be not mandatory for WIFI to work.

Just to say if you only need to replace the cable the from the main logic to the Airport card it is very simple after battery disconnect its just pry up logic board connector carefully then peel back tape at airport card and remove cable.

Thats all there is to the cable replacement and it fixed my No wifi hardware found and intermittent wifi which it would seem is a common fault As always a great guide thank you.

My macbook pro 13 2014 version wifi screen holder and the wifi card bluetooth cables are broken , so i went to repair it by my self and i bought the wrong full screen and the wifi card back to macbook pro 13 2010 version , it was shock so i would to know Can i change the wifi card cables and the screen adopted cable to the new cables of 2014 macbook pro 13 2014 version?

what's the difference between the normal "phillips screws" and the "shouldered phillips screws"?

Daniel Rathlef - Contestar

If you look closely with the screws (my eyes needed a magnifying glass) you will see that some of them have heads that are "stepped". hard to describe in words.

I just completed this repair successfully thanks to an excellent instruction and some help from iFixit support due to an error I made. A couple of comments that might help someone else:

1) make sure in step 15 that you TURN THE BOARD OVER and remove the tape from the bottom of the board. I "continued" removing tape from the top and then got completely confused when I couldn't find the screws in the next step. Yeah, it was my mistake because i didn't read the instructions carefully.

2) In step 15, leave the tape attached at the end of the bracket. this will make it much easier to replace the tape when reassembling.

perasso - Contestar

one further comment as to whether or not you actually need to replace the board.

I was having intermittent interference problems from other nearby bluetooth enabled computers. So I checked the signal strength and it seemed low. (you can do this by holding down the option key and clicking the bluetooth symbol in the banner, then you click on the device you are interested in). My BT speaker was at -68dbm (considered low) but was at -15dbm when it was at the same distance from my macbook 1.1 (i.e. white, plastic macbook). This is a huge difference (dBm is a log scale) so I replaced the BT board.

But after I replaced the board I measured again I got the same signal strength. I then checked it with another macbook pro and again I got the same signal strength.

So intermittent BT problems and low signal strength don't necessarily mean you need to replace the board. The macbook pro just doesn't have good BT signal strength, at least not compared to the old macbooks.

Notice when you replace the airport card that there is a precaution for handling: electrostatic sensitive devices. This could be why there is an error after replacement. Read up on dangers/handling and be extra careful during cold weather.

Liliana Chavez - Contestar

I replaced the airport card in my Mac following this instruction. At first, it seemed to work fine. Now, it is deactivated every now and then and I am not able to activate it again. As of now, a reboot seems to help but that’s not really a solution. Can someone help me?

Larissa Zech - Contestar

Can this BT be upgraded from 4.0 to 5.0?

jaskiran singh - Contestar

Sorry no ;-{

BroadCom stopped making the Combo board Apple was using. Note the connector to the logic board is on the face. The next generation uses an edge connector system and there is no means to upgrade to it.

The only way is to find a USB-A BT 5.0 dongle

Dan -

This totally fixed my Wifi/Bluetooth issue. Professionals at a certified apple repair shop told me the repair is to expensive , complicated and not worth it I should just buy a USB WIFI stick… so I replaced the airport board and the WIFI cable myself with help of this instruction, in the end it turned out that the board was fine (old board is back inside) and I only had a broken WIFI cable. Total cost 8,40€ WIFI board and 6,18€ for the cable, less than an annoying WLAN stick that doesn’t even support BT. Thanks a lot to the author!
