"10 Ways To Speed Up Your Mac": Clean Useless Startup Items
When you log on to your computer, it has a few programs that it loads as soon as it starts.
The more it has to load, the longer it will take to load. You can cut down the load time by removing some of these startup items.
To do this go to:
System Preferences --> Accounts --> (Click the account you want to clean) --> Login Items
There you can find a list of Applications that launch at the start.
Look through them to see which ones you don't need.
When you find one you want to remove click it to highlight it and click the minus button.
Do this with all the accounts you want. This will make your computer start and run faster!
