My Mac mini worked flawlessly until this evening when I was working with XCode and was trying to Compile some apps. Later on Reboot it worked properly again and then I Synced my iPhone and after the sync again it froze.
And now even after reboot, it loads all startup icons and freezes !!!
I can move the pointer and see Finder when I use Command + Tab. But I cannot open anything or minimise apps, etc.
Please help. I am new to Macs and dont know whats wrong !!!
