Picture of Upgrading RAM in your MacBook Pro 13
It is becoming increasingly popular to regularly upgrade RAM (memory) in your laptop to accommodate constantly growing appetite for web intensive browsing or running more instances of virtual machines. This instructable is describing the process of upgrading (or replacing) RAM in unibody MacBook Pro 13 and 15 inch models. I used 15" model in my photos, but the process is very similar in 13" MacBook Pros. So let's get started. I made it at TechShop (, they have a whole bunch of really convenient large tables in the common area with some great lighting.

Step 1: Acquire RAM for upgrade (or replacement).

RAM is cheap these days, so you can afford to buy more of it for less. I've been lately purchasing RAM for my Macs at, as they seem to have a good balance of price and quality. Here is what new RAM looks like in a packaging. For this process this is the only part you are going to need.

Step 2: Prepare your workspace.

Having a large space to work on is very convenient. For best result and safety I'd recommend using one of those anti-static mats and laying it on a large flat surface.

Step 3: Connect the ground.

Connect the ground wire of your anti-static mat to ground prong of any electric plug.

Step 4: Ground yourself with anti-static wristband.

This step is important. When working with electronics, have yourself well grounded with a wristband. Very little static electricity can send electronics of your computer into knock-out.

When wearing the wristband, make sure it's not too tight. Wear it entire time while you're working on internals of your computer. Even though you're well grounded, I would recommend not touching any electronic parts with your hands, as you're leaving natural oil behind. Washing hands before this job is highly recommended.

I see in other instructions online to disconnect the battery. What is your thoughts on that?

As long as you properly shut down the computer, you should be safe with battery plugged in. If you still want to unplug the battery, be sure not damage the battery connector -- it's kinda fragile.

Be sure to use removable thread locker, not the permanent type!

Hi Doctor Jazz, what is it you're plugging you anti-static wrist band into? I have a band but nothing to attach it to in my work area and something like that could be very useful.

There's a slot for it on the mat (the black plastic thing on the corner; need to remove the alligator clip first). If you're not using a mat, you can also clip the wrist band to the chassis (the metal case) of the computer (in which case leave the alligator clip on). The anti-static mat is the better way to go, though. All mats should have a place to plug wrist bands in on one of the corners. If you live in a dry area, use a water-based lotion on your wrist first to increase the electrical contact with your skin. Hope this helps.
