I am trying to install crucial CT2CP51264BC 1067 PC3-8500 DDR3 2x4g ram. I've rebooted but computer only reads 4g. Is there something I can do to get it to recognize 8?

First timer here on the discussion board. Is this thing working?

MacBook, Mac OS X (10.7.5)

Hi Juan,


I didn't see what OS you're running. However, I do know that I had to update my EFI Firmware with a Software Update and it solved my issues. You'll see it referenced by older posts as the "Secret Firmware" update, as they didn't specify in the update that it would permit macs to run more than 4gb of memory.


I'm now running 8gb in my late 2008 aluminum macbook.
