What you need

    • Remove the following ten screws securing the lower case to the upper case:

    • Three 13.5 mm (14.1 mm) Phillips screws.

    • Seven 3 mm Phillips screws.

    • When removing these screws, note how they come out at a slight angle. They must be reinstalled the same way.

    • For certain repairs (e.g. hard drive), disconnecting the battery connector is not necessary but is recommended as it prevents any accidental shorting of electronics on the motherboard. If you do not disconnect the battery connector, please be careful as parts of the motherboard might be electrified.

    • 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.

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

    • Remove two T6 Torx screws from each side of the hard drive (four screws total).

    • You'll need to transfer these screws to your new hard drive if you're changing drives.

    • If desired, peel the pull tab off your old hard drive and transfer it to the side of your new drive.

    • If you are installing a new hard drive, we have an OS X install guide to get you up and running. Many recent Macs may be able to use OS X Internet Recovery.

To reassemble your device, follow these instructions in reverse order.

Hi, Im going to replace my mac hard drive. Looking at this guide it seems that I wont have too much difficulty in doing so, but do i need to format the new hard drive before I replace the old one? or can I just replace it and then format it when I boot it up for the first time?

I have the MacBook Pro mid-2012 15" and I have installed Samsung SSD 840 EVO 2.5" form factor drive and it fits fine. Really makes the MacBook fast.
