Should i have made other edits ? Not the best at script. Until you get Jamf at your company, you can periodically run that command en masse via ARD if you have only edited timezone = and timeserver= Other than that, it works great! However the #1 thing that is required is that our internal server syncs to the atomic clocks the rest of the world uses.Д®DIT: I just realized you said you don't have Jamf yet. The only Macs that end up drifting are those used by people who go on 2 week vacations and their Macs don't check in during that time. So in order to get my Macs synced up, I have a command added on to our daily inventory collection: ntpdate -u 10.1.5.5 This makes sure that there is very little time drift at all on a daily basis. I also work in a HIPAA environment and our network admins have blocked all NTP syncing with Apple's servers, however our internal servers ARE synced up to other external atomic clocks. I think that would be your first order of business before you sync up to your company's internal server. If your internal time server is 9 minutes off from the Apple and Navy clocks (and presumably others) and your Macs sync up to it, that could cause SSL problems with external sites that DO sync up to atomic clocks. usr/sbin/systemsetup -getnetworktimeserver usr/sbin/systemsetup -setusingnetworktime on usr/bin/defaults write /Library/Preferences/ Active -bool true # set time zone automatically using current location usr/sbin/chown -R _locationd:_locationd /var/db/locationd usr/bin/defaults write /var/db/locationd/Library/Preferences/ByHost/.$uuid LocationServicesEnabled -int 1
