Thanks Camelot! I actually gave that a try this morning, and received an error that the framework resources were not available and that the command was not valid. (I'm paraphrasing) I also tried:
sudo date 1104211137
$ date 1104211137
Also using those same operators I tried the date format as: 201140211155.00
(I have no idea what I'm doing in the terminal, so I just took those commands based on various Google search results)
I also tried man systemsetup and going that route through those commands, with no success unfortunately.
Hey, i just run in to something similar, tonight while trying to fix a computer.
The user set the time and date on his computer to 1998 and computer locked everything including time and date in system preferences, and his user account basicly making him from administrator to guest. he could not almost any program properly that required administrator privilages.
to fix this we used this comand in terminal " sudo date 201703162014 " todays time and date
20:17 03/16 2014
we tryed everything and this fixed in 2 seconds
ps: when you type sudo in terminal it whil give you a warning the improper use of this command is bad.... click continue.otherwhise you will not be able to execute the command.
thanks again for this post and have a great day
I was been this problem, I changed date & time to 1995... and the mac blocked all application, so try in terminal:
sudo date 032913152015
Using this format:
usage: date [-jnu] [-d dst] [-r seconds] [-t west] [-v[+|-]val[ymwdHMS]] ...
[-f fmt date | [[[mm]dd]HH]MM[[cc]yy][.ss]] [+format]
THANKS A LOT OF!
