Rewhat now?

Of course a reboot fixed it. I typically don’t reboot my Mac unless there’s an OS upgrade or some kernel-level installation. I think the last time was a month ago when I installed Korg’s midi driver to try and deal with an issue with the new version of Logic.


Thanks for not saying that, because you don't normally reboot, that couldn't have anything to do with it.

Your problem, as you may have figured out, was not enough free RAM. Memory leaks are am unfortunate fact of life. Browsers, browser plugins, apps and their plugins... you never know what's going to be the culprit and it can come from Apple, too. There are ways to find out — Google is your friend — but knowing doesn't mean you can necessarily do anything abut it.

When I had only 32GB onboard, I was ok up to about 30 hours and my apps looked like your video by around 36. With my new iMac Pro, I have 128GB onboard and am good through 5 days but things will lock up on day 6.

My music industry day job has me logged into 120–150 sites on 3 monitors at any given time. I know where the problems are and how to end processes and so on... but I still have to make a living and a reboot/log-in takes 45 seconds in the morning.

If happens again and a reboot is impractical, you can free up some RAM by running sudo purge in Terminal. It won't free up as much as a reboot but it might get you out of a jam. All sudo commands require an Admin password which will be good for 15 minutes.

Before I replaced the HDD in my 2010 iMac, a reboot and login took 20 minutes. I ran sudo purge somewhat often.
