I have a mid-2009 MacBook with 4 GB of RAM installed in it and I'd like to upgrade it to 8 GB of RAM. In order to do that I have to figure out what the installed RAM configuration is so I can determine what it is I need to order.

How do I see the installed RAM configuration in the MacBook without opening it up and actually looking inside?


You can see the current RAM configuration in a visual overview by:

  1. Going to the  menu
  2. About this Mac
  3. more info
  4. memory

enter image description here

If you'd like further detail, open the System Report... from the Overview tab of About this Mac. This can also be accessed by holding while the  menu is open, then selecting System Information.


To see the RAM installed in your MacBook without opening it up:

  1. From the Apple menu (the little Apple icon in the upper left hand corner of your main monitor), select About This Mac. In the window that appears the total memory installed on the machine is listed.
  2. To see the details of what's installed click the More Info... button and in the window that opens select the Memory tab. This will show you which slots are filled in your MacBook and how much RAM is installed in each slot. There's also a link on this tab that will take you to instructions for upgrading the RAM in your MacBook.
