I have 2010 MacBook Pro and almost for one year every thing was fine until the past couple of weeks it started acting vey weird !! every one hour my MacBook pro freezes up for 30 seconds , every thing is stuck except the mouse !!
I ran repair disk and repair disk permission and everything is fine ! I also cleaned by CleanMyMac and still the problem is there !!
I have Mac OS X 10.6.7 2.4 GHz Intel Core 2 Duo 4 GB RAM
Any help will be highly appreciated ! the problem is driving me crazy !!
30 GB of free space is most likely your problem. Any time a disk is more than 80% or so full it will cause your computer to exhibit this symptom. All you can do is delete some files or move some files to an external hard drive.
My Macbook Pro started doing this a few weeks ago. It turned out the hard drive was faulty with SMART errors. It was replaced and all is good now (except I now need a new battery but that's a different story!)
