I generally run a Windows setup so that’s what I’m more familiar with, but I have a 2018 MacBook Pro which I use pretty much every day.

I always keep iOS and everything on it updated and updates are rarely done more than a couple of days after they come out.

Today however I went to use it and the battery had died. I plugged it in, gave it a moment and then powered up.

Immediately I noticed the time was for some reason showing as 11:36am, even though it was 6:24pm, but the date seemed to be ok and everything was working.

Within 5 minutes some things stopped working, and then I noticed the time now showed as 10:30pm in September 2021. I then tried running MalwareBytes (came up clean), restarted the computer, no change.

I went into the settings and all the time/date stuff was set to auto, with the correct geographical location displaying. So I turned off “Set time and date automatically” and manually set the time and date, and that worked fine.

As soon as I turned it back on though the date switched back to a random time and date in late 2021.

It also seems to have logged me out of a load of things including my AppleID etc.

I don’t want to go logging into things until I know there isn’t a security concern, does anyone have any suggestions what this could be?

    I bet if you return the option to Automatic it will resolve. Time isn’t updated every second.

    As for why things stopped working many components of macOS are cryptographically signed. Without a proper system time these signatures will fail to authenticate and things will stop.
