Hey guys. I purchased my MacBook Pro in May this year. Been enjoying it, but since some time in August, it has started to bombard me with beach balls. I usually run three apps, Firefox, Adium and Transmission at all time. Firefox is what lags out the most, it's quite annoying and can sometimes be for up to two minutes, where I am unable do ****. Right now, after a complete reboot, I even experience the cursor lagging (stops for a very[/] short time), making me miss-click almost everything. (And this is both my mouse and my track pad!) I often run the app called Onyx, to clean up things. I don't have much experience with Mac, so please tell me if there's any more information you need, in order to help me MacBook Pro (early 2010) i7 2.66 ghz 4 gb ram 15.4" high res display Often running an external display through mini display to HDMI (23" 1920*1080) Any help is appreciated.
