How to Change Memory on Mac

Recently, we got iMac 2011 into our hands. It had the minimum amount of RAM that could be set for its type – 4GB. In 2016, that is sorely inadequate. It was therefore decided to add more RAM memory. And in this article, we will tell you how to do it correctly.

Check up

First, check your device and the possibility of an upgrade and the maximum possible value on Apple website.

In our case, iMac had 4 slots for a maximum of 8 GB. 32 GB in total. It has 2 sticks of 2 GB and 2 free slots. We had 2 free sticks for 8 GB each. So, we received 20GB RAM in total.

Ideally, try to pick up memory so that all modules had the same volume, preferably the same manufacturer and series. But if, for whatever reason, you don’t – it is not critical.


So you checked your iMac, bought additional memory, now it’s time to prepare a working place.

You will need to lay down your iMac on the screen. So make room on the table, or better on the couch if it not soft. Make sure that the surface is solid without extra objects on it like pens, keys and anything else that can scratch the screen.

You will need a simple crosshead screwdriver as well we advise to cut fingernails before ūüôā

Gently pull the plug, do not be afraid to lose screws, they are attached to a special washer. Put a screwdriver, then everything we do with fingers, so not to damage contacts.

You will see a small space with two tenons of a material resembling a tape, only much stronger. Tenons bend simply by swiping with your finger.

Once you bend tenons you will be able to pull out a memory module, if you want to replace them. Take with one hand tenon, with a second Рhold a Mac, as it may fell off the table. Drag quietly, gradually adding force until you see that the memory is out of a slot. After that do not pull over, but carefully remove memory manually.

The same can be fulfilled from the other side.

Inserting New Memory

Connectors for RAM on the Mac are divided into 2 blocks by two planks. Each tenon is responsible for its unit. To insert a memory, take it in your hand as shown in the photo.

As you can see the edge responsible for the connection (colored with yellow) is divided in a ratio of 2/3 to 1/3. RAM should be inserted the way that narrow part (1/3) was right. Otherwise, it won’t work, but with zealous attempts you may damage pin connectors on the module or even worse – on iMac.

Insert the module into the vacant slot until you feel that you have rested in something. Thereafter, as with tenon, gradually adding pressure insert module to the end. Then gently fold the tenon on the spot.
