How to Buy RAM for a MacBook

Assess the applications and programs that you are going to run and the amount of RAM required for it. Applications having graphics and multimedia require more RAM and, without it, can often reduce the speed of your machine.
Check the existing configuration of RAM on your MacBook. For this, go to the 'Apple' menu and select 'About This Mac' to get the memory report. Also refer to the pie chart that is provided. Remember, yellow and red indicate the need to increase the amount of RAM.
Discover the maximum RAM configuration that your MacBook can support. For example, a MacBook 1.83 GHz has a fixed memory of 512 MB size and can support up to 2 GB of RAM. Similarly, a MacBook of 2 GHz has a fixed memory of 1 GB size and can support RAM up to a maximum of 2 GB.
Log on to the Apple Web site and note the specifications of MacBook. Determine your exact RAM requirement. Find out about the need to buy RAM through the OS X's Activity Monitor.
Contact Apple or other dealers that sell RAM for MacBook. It is always recommended to buy RAM from the manufacturer of MacBook so it won't cause kernel problems.
