Ive genius appt book for Sunday afternoon as my mcbpro wasn't booting at all last night/today just the white apply logo...nostartup sound/blank screen
Only had this brand new a few moths ago...why would such a reset be required? no complaints just thinking is there an underlying fault to consider...i.e. ram/ssd/power
edited 1st update required Yosemite beta 4...is there a better time to consider this update considering what happened last though beta 3 was running excellent
