My iMac is constantly freezing and getting slow without any explanation. There is nothing being executed, and iTunes breakes the music being played.. Finder sometimes slows down and the rainbow spining wheel shows up. Using Autocad is now very slow and any movement i make can cause a freeze or a crash..

Also, the Play, next and previous song, brightness control, mission control and launchpad buttons on keyboard just don't work (already checked de Function buttons options..).

 

When I had Mountain Lion installed, it was a mess too. The computer used to shut down from time to time, but it was rarely slowed down while working..

 

Very angry with this, almost backing to Windows slow iMac with Mavericks
