    • Entferne die folgenden zehn Schrauben:

    • Drei 14,4 mm Kreuzschlitz #00 Schrauben

    • Drei 3,5 mm Kreuzschlitz #00 Schrauben

    • Vier 3,5 mm Kreuzschlitz #00 Ansatzschrauben

    • Wenn du die kleinen Schrauben wieder einsetzt, neige sie ein wenig, wie auch das Gehäuse geneigt ist (sie gehen nicht gerade hinein).

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

    gunes314 -

    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.

    Marshall WahlstromHelgren -

    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 -

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

    taylornya -

    iFixit sells a kit: MacBook Pro Unibody Lower Case Screw Set

    Darrell Johnson -

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

    rodrigosady -

    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 -

    We have a guide for that!

    Wie man eine rundgedrehte Schraube entfernt

    Sam Omiotek -

    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 -

    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.

    Iain Boyd -

    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.

    Patrick Langvardt -

    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.

    Gary Register -

    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.

    Degeorges -

    Bonjour ! Merci de votre observation. J’ai corrigé la traduction. iFixit étant un wiki, n’hésitez pas à modifiez si vous remarquez une erreur :) Encore merci de votre attention et à bientôt !

    Claire Miesch -

    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

    • Löse mit der Kante eines Spudgers den Akkuanschluss nach oben, weg vom Sockel auf dem Logic Board.

    • Es ist hilfreich, beide kurzen Seiten des Anschlusses gleichzeitig nach oben zu hebeln. Sei vorsichtig mit den Ecken des Anschlusses, da diese sehr leicht abbrechen können.

    Is this step of removing the battery connector required?

    manodh -

    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 -

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

    Phil Wagner -

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

    Reinhard Kaune -

    • Biege das Akkukabel vorsichtig weg vom Sockel des Logic Boards, damit es sich nicht aus Versehen beim Arbeiten wieder verbindet.

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

    Stephen Smith -

    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 -

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

    Jerry South -

    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

    • Hebe den Verbinder zum Airport/Bluetooth Kabel mit dem flachen Ende des Spudgers aus seinem Sockel auf dem 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.

    • Ziehe vorsichtig das Kamerakabel aus seinem Sockel auf dem Logic Board.

    • Ziehe das Kabel parallel zur Oberfläche des Logic Boards. Wenn du es nach oben ziehst, kannst du das Logic Board oder das Kabel selbst beschädigen.

    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 -

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

    VÍCTOR RIFFO -

    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.

    • Schiebe das Flachbandkabel von Airport/Bluetooth vorsichtig aus dem Weg und löse das Kamerakabel von der Klebeverbindung mit der es am Subwoofer und der Halteklammer angebracht ist.

    • Fädle das Kamerakabel aus dem Bügel in der Halteklammer von AirPort/Bluetooth.

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

    • Hebele den Antennenverbinder, der am nächsten zum Logic Board ist, aus seinem Sockel auf der Airport/Bluetooth Platine hoch.

    • Fädle das Antennenkabel aus dem Bügel in der Halteklammer von AirPort/Bluetooth.

    • Löse mit der eben beschriebenen Methode die restlichen drei Antennenverbinder.

    • Fädle ihre Kabel aus den Ausschnitten in der Halteklammer von AirPort /Bluetooth

    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 -

    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?

ahat2013 -

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

Daniel Rathlef -

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 -

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.

perasso -

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 -

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 -

Can this BT be upgraded from 4.0 to 5.0?

jaskiran singh -

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!
