Making Sure Your MacBook Recognizes the New Memory
After installing additional memory in your MacBook, check whether the computer 
recognizes the new memory. 
To check the computer’s memory:
1Start up your MacBook.
2When you see the Mac OS X desktop, choose Apple () > About This Mac.
For a detailed breakdown of the memory installed in your computer, open System 
Profiler by clicking More Info, and then click Memory. 
If your MacBook doesn’t recognize the memory or doesn’t start up correctly, 
confirm that the memory you installed is compatible with your MacBook and that 
it’s installed correctly.
