Since installing the Sequoia update, my Mac Mini freezes up nearly every time it goes to sleep. I can see my wallpaper, and sometimes can see the bar at the top, but it is greyed out, and I can’t do anything with my mouse or keyboard. I’m having to turn off and restart at least once a day. Anyone else? Any ideas?
Mac mini, macOS 15.3
I had the same problem with my Mac Mini 2018. It seemed to happen regularly to the point that I just turned it off after each use with hopes that a future update would fix the issue. When Sequoia 15.3.1 came out, I waited a week (as per my usual) to install it. After I did install it after being satisfied that others were not having problems in general, the sleep issue seems to have been resolved. Granted, I haven't used the machine as much the last month but I was satisfied the problem was resolved after letting it run nearly a full week without powering it down. My Mac Mini resumed operations fine many times during the day and overnight.
You don't say what year/iteration your Mini is - and you do state that you are running 15.3.1 - just saying that this version seemed to fix my Intel-based Mac Mini.
Have you tried updating to the most recent? Your post says "Mac mini, MacOS 15.3" but there is a 15.3.1 version out now.
Many reporting issues using sleep. Do not use. Just have display turn off after a set time
I just checked, and I am on 15.3.1. It seems the crash is being caused by IntelligencePlatformComputeService. When I Googled that it says to toggle off Apple Intelligence, but we have already done that as well (2 days ago). I'm including a screenshot of the crash report.
Need to restart every time computer sleeps after Sequoia update
