How to Optimize Your Mac.

It is not uncommon for computer systems to slow down over time. The cause of diminished speed can be malicious, such as viruses and spyware on the hard drive. Slow speed can also result from application overload and out of date software updates. Mac computers have a reputation for being less prone to complications than other systems, but even Macs can become slow. Even if your Mac hasn't slowed down enough to affect the speed, optimizing your system can improve performance.
