How to Add Macbook Memory

Shut down and unplug your MacBook.
Open the computer case by loosening and removing the eight small screws around the edge of the computer back.
Discharge any static electricity in your body by touching a piece of metal. Static charges can damage sensitive components inside your MacBook.
Locate the memory card(s) toward the right side of the back of the computer.
Remove memory card by pressing the levers on either side of the memory card(s).
Install new memory card by inserting it at an angle into the memory slot the same way you removed the old card. Apply steady, even pressure and do not force the device into place. Repeat the same process for the second memory slot.
Close the computer case by snapping the bottom plate into the same position it was when you removed it. Replace the screws and tighten them firmly.
Plug in and start up your MacBook. It is ready to use with its new memory.
