Chapter 4 Adding Memory to Your MacBook 87
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:
1 Start up your MacBook.
2 When you see the Mac OS 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 Memory.
If your computer doesn’t recognize the memory or if it doesn’t start up correctly, shut
down your MacBook and check the instructions again to make sure that the memory
you installed is compatible with your MacBook and that it is installed correctly. If you
still have problems, remove the memory and consult the support information that
came with the memory or contact the vendor who provided the memory.
