Hello, sorry for the CAPS subject, but be aware, i got my 12 Core on friday, after 2 Time machine Restores, and 4 Clean Installs, i Apple Store visits, i finally figured out what it is: DO NOT INSTALL PARALLELS !!!!!!! It is not compatible with the 12Core, it messes up something with the Kernel, spend hours of installing everything and then once i install Parallels, it Panics and will not reboot! I had it all nice on my time machine, but no luck!!! be aware!
