Hey guys, My early 2012 MBP is now running crazy slow and sluggish, with much more beach ball and just grindingly slow performance. I look at activity monitor and there is a process called "kernel_task", the user is "root", and the percentage of CPU is 525-595 percent!! 91 threads and 594.3 MB real memory. Details: 15" MBP Late 2011/early 2012 2.4 GHz Intel i7 8GB (now) Mem AMD HD 6770M 1024 OSX Lion 10.7.5 I upgraded the RAM from 4 to 8 GB about 6 months ago, mainly because I wanted quicker performance in general and for doing multiple things; that said I never "tax" this computer at all, just internet/email/vlc movie/mail open maybe. This upgrade didn't seem to do much for improvement. Slowly my performance has been getting worse and slower. I have ~750GB of space; which about 600 of was used but I cleared a bunch out recently so there's 540GB free now. I don't know what this kernel_task crap is yet, i'm googling, but I don't remember seeing it in the AM list before; firefox is right under it at 21% CPU. I've reset PRAM a few times, and might try to reset SMC or..MRS... or whatever that other accronym one was. I only recently started using firefox (again) instead of safari, and I've recently added some add-ons to firefox and been using duck duck go search engine. Anyways, any help is much appreciated Thanks for your time.
