Solved Mac Pro 13.3 will not start after downloading Maverick

October 31, 2013 at 17:40:29
Specs: Mac Pro 13.3 OSX 9 Maverick , 2.4/2x2GB/500
Downloaded Maverick and everything seemed to work. The next day the keyboard stopped functioning. Went through the suggested remedies from manual and it did not help. Could not type my password to get onto the computer. The next day I could not start the computer. Tried left shift key, left option key, left control key and the power button simultaneously. Nothing. Tried power button, command key, option key, P&R keys simultaneously. Nothing . I am stumped. Battery is working 100%.

You've installed Mavericks on OSX 9?

OSX Mavericks is not compatible with OSX 9.

It requires OS X 10.6.8 or later
