iMac crashes 5 x a day and beachball, what to do?
My iMac 27'' end 2009, Intel, OS 10.7.4, is crashing 5 times a day and showing the beachball, usually after some time, not immediately. Then i have to use the button to shut down. After running Tinkertools or using safeboot it works again for some time, till the next crash. DiskUtility, Onyx, DiskWarrior cannot help. What can i do? Please help.
Mac OS X (10.7)
