Obviously, I am still learning the Mac way....
On the PC...Ctrl...Alt...Del...can see all the processes running. Is there a similar feature with the Mac and also are there processes running that shouldn't be running, a la the PC? (blah.exe) I know specific processes that do need to be running.
Also, are there programs that auto load on startup that I may not want to be running, again on the PC there are a number of obnoxious programs that run automatically...W Media Player, Real Player, Limewire.
