I have the new MBP 13" 2.4ghz, and I installed 'Little Snitch' last night. Once I started running it my MBP was running extremely slow, close to the point of locking up. I was not running many other programs, just mail, iCal, and Safari. Has anyone else had this problem? I like the idea behind 'Little Snitch' I just don't want my computer dragging along like a snail.
