Image 1/1: If you don't have a Pentalobe driver, a 1.5 mm flathead screwdriver can be used in a pinch. Be sure the head of your flathead screwdriver fits snugly across two of the five "points" of the screw head before trying to break the screw free, as a loose fit will easily strip the screw head. If the head of your screwdriver fits too loosely, find a bigger bit and file it down until it fits snugly before proceeding.
  • Three Pentalobe screws secure the battery to the upper case. They can be removed with this special driver.

  • You do not necessarily have to follow steps 3-7 to remove the battery in order to replace the hard drive. However, it is recommended to remove all power sources from electronics before working on them.

It really depends on how thick the 1.5 mm flathead screwdriver is. I tried a low-cost tool and almost destroyed the screw. So be carefull

Unfortunately, when I added a second hard drive via these instructions, all went well but Bluetooth is now MIA. Can anyone help?

I agree...

I have bought a used MacBook Pro, when problems arise, opening Corps was trying to turn the screw, but with poor quality could not turn a screwdriver, only to ruin the screw. Try to buy ifixit Screwdriver set. Good luck to all and thank you ifixit team for such assistance as ifixit.com. Thank you.

  • Remove the two exposed five-point Pentalobe screws along the top edge of the battery.

The screws holding my battery were all worn out since an earlier removal. So instead of ruining them even more I put some saran wrap on the tip of my pentalobe driver and gently unscrewed them.

  • It is useful to twist the spudger axially from beneath the fan cable wires to release the connector.

  • The fan socket and the fan connector can be seen in the second and third pictures. Be careful not to break the plastic fan socket off the logic board as you use your spudger to lift the fan connector straight up and out of its socket. The layout of the logic board shown in the second picture may look slightly different than your machine but the fan socket is the same.

  • Apple sticks a small strip of clear plastic with adhesive applied to one side to the logic board behind the camera cable connector to keep it in its socket. When moving it out of the way, be sure not to break any surface-mount components off the logic board.

Be very careful to not get under the connector base on the logic board. You can pull it off. It is only secured by weak surface mount solder.

I second that sentiment. The connector base is slightly elevated off the logic board, and it is easy to get your tool under that instead of the male plug you're trying to disconnect. I pulled mine off, and for now the speakers are tinny.

  • Carefully lift the logic board assembly from the left side and work it out of the upper case, minding the port side that may get caught during removal.

  • Do not entirely remove the logic board yet!

  • Ensure that the logic board is free from all connections to the upper case (except the battery connector) before proceeding.

I,ve done everything up to this step but my logic board still seems to be connected (by glue i think) to the black plastic underneath and the black frame that can't be unscrewed. Any idea how to get past this?

For step 24, the same thing happened to me as did to Josh. The heat pipe had bonded with the plastic film which protects the back of the keyboard. By using a spudger i was able to pry at the area where the two were attached. I don't think this is intentional, they just melt together.

Same happened to me. Matt is right. I gained extra clearance by removing both RAM modules. Then used the spudger. Sounds cracky but it´s all fine.

  • Lift the logic board enough to gain clearance and use a spudger to pry the microphone up off the upper case.

  • Slide the logic board away from the port openings and lift the assembly out of the upper case.

  • Before reinstalling the logic board, it is easiest to press the microphone down into its housing in the left speaker to keep it in place.
