My Mac is Super Slow all of a sudden!

I don't know] this for sure, but it looks like iTunes is eating up your system process...more than iMovie, and that's a bit weird to me.

Other than that...not sure. But Quit all apps, Restart Finder, and see if your Mem and CPU usage drops. Then start them one at a time for normal use, and see where it really starts to whine...then consider a repair or reinstall of that software...maybe.

 

lot of people i know have been saying the same about there mac everything they has in common was FireFox. it seems the lastest update slows FF considerably.

try using Safari for a few hours instead of FF (reboot first) see it its still slow

 

Try running an app called rember it will tell you if there are any faults with your ram.

 

I'd concur with the sentiment that Firefox is the culprit, based on the fact that it always slowed my Macs down ('06 whitebook, '09 iMac). Part of that may have been that I run a lot of add-ons through it, but frankly, if I can't use add-ons with Firefox then I have no reason to use it, period.

Safari is a superior browser anyway, imho. Best thing to do is download Chrome and try that instead, probably not a popular opinion to share on a Mac forum, but that browser is lightning fast and super slick and I reckon the best browser out there (even if it isn't fully finished yet).

 

Another in agreement that it might be FF, but I like the addons too much to switch. Hopefully FF 4 will solve any memory issues.

 

If it's firefox...would some of the add-ons work in Camino (also by mozilla)? I used to use it on my MbP and it ran much better.
