Hi, can someone please help me. I am at the end of my rope.
My MacBook Pro 13" 2.4 GHz i7 , 4GB DDR3 RAM,Intel HD Graphics 3000 (early 2011 model), OS X 10.8.2 (mountain lion)
has been driving me crazy for the last 2 weeks.
Its been excessively lagging & the fan is up at full speed. (constantly)
Its so loud its worrying.
Previously it ran so hot it would burn my lap, now its ice cold.
But the main issue is:
Activity monitor indicates constatnly CPU usage by system at 84% with NOTHING running!
Its seems like a runaway app, but i cant find anything.
Only the Kernel_task shows 324% CPU
My user usage is sitting around 2 - 7% ( 5 - 7% if i patiently try to run anything)
I've tried the PRAM & SMC resets, with no results.
I've spent 2 full days at my nearest iStore, only to be told they have no clue, its very strange & they cant help, they have to send it to some repair centre which wil take up to 4 weeks before i can get my macbook pro back.
I need it for work & studies. ( part time student, looking for part time work)
It did suddenly come right again last night and worked normally, but after i closed the lid and left it all night, it was back to the problem when i opened it this morning.
I cant afford to send it away for 4 weeks.
And this will be the 3rd time they've sent it away for mystery problems.
I need help to sort it out myself.
All help greatly appreciated, thanks
