Hey everyone, My iMac froze yesterday and I switched it off by holding down the power button. After that it freezes during bootup on the apple logo and the spinning wheel. I ran disk utility and it said that it cannot be fixed so restored everything from a time machine backup. Didn't help I've tried safe mode, pram reset, repair disk says it's ok Verbose mode stopped with Setfixedspeed logic error speed any? Can anyone help me? Thanks!
