How to Update the RAM on a MacBook

Updating RAM lets you run more applications at once, and faster.

RAM (Random Access Memory) is the type of computer memory that allows you to run applications, programs and processes on a computer. The more RAM you have, the more you can run at once without your computer slowing down. It is typically easier to change hardware in desktop computers since they have more space, but you can also change and update your RAM in laptops. You can change your MacBook's RAM by using a screwdriver to remove the bottom casing to access the pre-existing hardware.

Things You'll Need

• New RAM cards
• Phillips-head screwdriver

Instructions

1. Turn off your MacBook, close the screen, then unplug all the wires and cables connected to it. Turn the laptop over and place it on a flat, stable surface. You can set the laptop on a cloth to avoid scratches.

2. Remove the eight screws on the laptop's bottom casing (four on one edge, four on the other) by using a small Phillips-head screwdriver. Carefully turn the screwdriver counter-clockwise to remove them. The screws come in two different sizes, so set them in two separate groups so you can put them back easily.

3. Remove the bottom casing, then set it aside to reveal the inner components and hardware of the MacBook. To avoid static electricity damage, touch a bare, metal surface inside the computer to discharge your fingers and hands before touching the RAM.

4. Locate the memory module on the inside of the laptop casing. Press the release levers to unlock the existing sticks of RAM, then gently remove them by holding the outer edges of the sticks.

5. Insert the new RAM sticks by gently sliding them into slots where the existing sticks were, aligning the gold edge and notches with the slots. Apply even pressure to the RAM stick and gently push downward to lock it into place. Both sticks should be level with each other.

6. Replace the bottom casing on the laptop's frame, then insert the screws back into their respective slots. Turn the screwdriver clockwise to gently tighten them back to their original positions. Be careful not to tighten them too much, which could damage the screws and/or casing.

7. Turn your computer on, then log in. Click the Apple icon, then click "About This Mac." Next to "Memory" it should show you how much RAM you have installed. If the number (for example, 2 gigabytes) matches the amount you just installed, the RAM has been installed correctly and you can continue using your laptop normally.
