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 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.

5Troubleshooting
If you have a problem working with your MacBook, 
check here first for solutions and advice. 
When you have a problem working with your MacBook, there is usually a simple and 
quick solution. Think about the conditions that led up to the problem. Making a note 
of things you did before the problem occurred will help you narrow down possible 
causes and find the answers you need. 
Make a note of the following:
ÂThe applications you were using when the problem occurred. Problems that occur 
only with a specific application might indicate that the application is not compatible 
with the version of the Mac OS installed on your computer.
ÂAny software that you recently installed, especially software that added items to the 
System folder.
ÂAny hardware that you installed, such as additional memory or a peripheral.
You can also find more troubleshooting information in Mac Help and on the Apple 
Service & Support website at www.apple.com/support.

Problems That Prevent You from Using Your Computer
If the computer doesn’t respond or the pointer doesn’t move
ÂPress Command (x)-Option-Esc to force a frozen application to quit. In the dialog 
that appears, select the application you want to quit and click Force Quit.
Next, save your work in any open applications and restart the computer to make sure 
the problem is entirely cleared up. 
ÂIf you are unable to force the application to quit, press and hold the power (®) 
button for a few seconds to shut down the computer.
ÂIf the computer still doesn’t respond, try to restart it by simultaneously holding down 
the power (®) button and the Command (x) and Control keys.
If the problem occurs frequently, choose Help > Mac Help from the menu bar at the top 
of the screen. Search for the word “freeze” to get help for instances when the computer 
freezes or doesn’t respond.
If the problem occurs only when you use a particular application, check with the 
application’s manufacturer to see if it is compatible with your computer. If you know an 
application is compatible, you might need to reinstall your computer’s system software.
