I used to have problems in Mavericks and Lion at different points in time. YMMV.Īs of today, I run Mojave, Mavericks and Lion: Mavericks and Lion are on the internal drive while Mojave is on the external one.

That worked for me after Googling and pulling hair for a few minutes. Restart automatic time zone in System Preferences / Date & Time / Time Zone.In Terminal sudo rm /etc/localtime to remove the incorrect link.Turn off the automatic time zone in System Preferences / Date & Time / Time Zone.It should be a link to the IANA timezone database like so (assuming this Mac is near LA): lrwxr-xr-x 1 root wheel 45 Aug 30 17:32 localtime -> /var/db/timezone/zoneinfo/America/Los_Angeles This continued through reboots and toggling all the options in Date & Time. The Mac could detect where is was (both using the Maps application and the red pin in System Preferences / Date & Time / Time Zone showed the correct location) but the time zone was 'stuck' in the place where I was last week. Kept trying to change so that the Mac's location would automatically update the timezone.
