Downloaded Mountain Lion from the App store.  The installer shows "This disk cannot be used to startup your computer".  I tried to adjust the partition size as suggested and still wont install.  Checked permissions, Checked partition map scheme = GUID,  Verified Disk, Smart Status = verofoed...etc.


Anybody got any ideas.Screen shot 2013-03-11 at 11.41.18 PM.pngScreen shot 2013-03-11 at 11.45.57 PM.pngScreen shot 2013-03-11 at 11.46.15 PM.png
