It started close to a week ago. It will work normally for like an hour or so, then it randomly starts lagging. Every time I try to click something, the beach ball of death appears for 30 or so seconds, everything that I have open just STOPS working and stops responding. This will happen for maybe 15-30 minutes, then it will return to normal, then it'll go back to being laggy.
- I haven't used more than 1/4 of the hardrive space, so its not short on space.
- I've used disk utlity, and the SMART status said Verified, so my hardrive seems to be OK.
- I've used repair disk permissions from Disk Utlity, an everything came out fine.
- I've cleaned out all my caches with CCleaner, it took out 9gb of ****. This helped for like 15 minutes, then it went back to being really ******* laggy.
This has been ******* me off to the point in which I don't use my laptop because I can barely do anything for more than 30 minutes without it lagging. .
I/m thinking of just reinstalling Mountain Lion. My qquestion with that is, if I partition my external hardrive between my backup data files and the new OSX, will I lose my files from the other partition when I reinstall mountain lion? Will it wipe the whole external hardrive?
What do you think is wrong with my mac? What other ways could I try and fix the problem?
My macbook is a late 2011 15 inch pro. I bought it in September 2012 at my school, fresh in the box, no reburishing.
I didn't put any programs on in the past week that would have caused this.
Its ******* me off.
**** IT TOOK ME MORE THAN ENOUGH TIME TO TYPE THIS BECAUSE OF THE ******* LAG
