Sorry to interrupt the post a little bit. Actually Mac OS X is good at of taking care of itself, if there are performance issues, there are a couple of things you can check: * Check your Login Items under System Preferences > Accounts to see what you have automatically launching.Also check /Library/LaunchAgents/ and /Users/yourusername/Library/LaunchAgents/ for items launching at startup * Launch Activity Monitor and change "My Processes" at the top to "All Processes". Then see what may be consuming your OS X system resources. * Check the System Memory tab at the bottom of Activity Monitor to see if you have excessive "page outs", a sign that you may benefit from more RAM. * Check if you are running any poor Mac anti-virus programs as they may take large resouces. If you don't want to do these manually or the above check still won't help, let [http://www.anysoftwaretools.com/speed-up-mac.html|this Mac tuneup utility] to perform a health check of your Mac and fix relevant issues easily. Hope this help, best regards.
