Dont have much to go on here, but im curious to hear anything from those who might have some ideas. So for the past 4 days my computer has been at an apple authorized service center and authorized reseller for service in hammond, la for repeating keyboard letters and password mismatch issues - my user password seems to be different for login vs password used for user preferences. They should be the same. The service center has been telling me that they have been unable to "access" the system in order to run diagnostics or do firmware update. "The system wont let us do it".
For those who might be familiar with how premium apple authorized service centers are run, shouldnt they after 4 days have been able to access an ulocked system in order to diagnose?
