Perform a #12 OnyX cache cleaning routine, it also will check the drive and repair permissions (but not user permissions)
Also do #6 to reset the User Permissions and any others as needed.
I simple had to restart the Mac pressing SHIFT key for a "force restart" so i can check the disk. It was not about permissions i've tried that before.
Note: The actual problem was the finder was bugged and the desktop as well, i couldn't even right click on the desktop or anything like that.
Thanks for your time guys !
