I have a eMac with MAC OS X ver 10.3.9. I am not familar with Mac. I am trying to open a quickbooks pro program with no luck because the date and time settings are showing 1/1/1970 5:11pm. When I go into preferences to change the date/time, it is locked and I do not know the name/password to unlock it. Is there any way around this lock function - maybe a master user name/password to help with these type situations. Any help would be appreciated.
