- With old school black or white Macbooks, you'll want to first take out the battery.

- Under the battery component, you should see a metal guard. Unscrew any screws and slowly ease this out.

- There should be a slot on one side for the hard drive. Grab the pull tab and slide that out gently.

- The drive itself is encased in a sleeve. Using a torque screwdriver, remove the screws holding the sleeve on and remove the sleeve.

- Now take the new drive and place it into the sleeve and reverse the process.

- The new Macbook configuration (including Macbook Pros) requires a different method. First, flip the Macbook upside down and remove the screws securing it from the back.

- You'll see the hard drive secured by a bracket. Unscrew the bracket and remove it gently. You should be able to slide the drive out now.

- Detach the cable and remove the screws from the side of the drive. Now fasten those screws onto the new hard drive and attach the cable to it.

- Replace the hard drive, following these steps in the reverse order.

- Carefully follow these steps in reverse order to put your Macbook Pro case together again. Make sure you remember to attach the keyboard ribbon to the logic board.
