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.

The guide states you must remove the battery in order to replace the hard drive. This is incorrect- it is merely a safety precaution. If you do not have the specific pentalobe screwdriver, DO NOT ATTEMPT THIS. I just replaced a hard-drive in one of these macs, that someone had already stripped the screw head. The screws are tapered too, so no getting it out once stripped.

The battery does not interfere with this repair, so simply remove the two screws on the hard-drive bracket (step 8), replace the drive then put the mac back together.

Does replacing hard drive remove Moutan Lion OSX I did download update and don't have disk. Also how to transfer files to new larger GB hard drive

If you have problems when installing Mavericks after the battery has been removed maybe your Mac has the wrong date and time.

In Mavericks installscreen, start the terminal, type "date" and enter...if the wrong date is displayed type:

date {month}{day}{hour}{minute}{year}

Every bracket should be replaced with a two-digit number. For example, March 18th 2013 12:50 would become the following command:

date 0318125013 + enter

Actually I could just lift the battery connector without removing the battery at all. Worked out fine for me.

Thanks for the guide. I honestly feel like I got a new Mac. I installed one of iFixit's hybrid 1TB SSD (SSD with backing HD). My Mac was unusable and painful to use it was so slow. Now it's like brand new.

Removing the battery connector was hard to do with finger force alone, I had to entice it with a flat head screw driver. Getting the full iFixIt toolkit gives you all of the tools except the spudger which really could be improvised with something else.
