You shut your computer down because of a problem - finding the problem
I'm on a Mac desktop running Ventura 13.3.1 with a second Apple monitor, Logitech keyboard and Evoluent ergonomic mouse. No problems with this set up for literal years but over the last 10 days I am getting the message 'You shut your computer down because of a problem' and I do not know what this problem is. I thought it was the Proton bridge software that allows me to use Mozilla Thunderbird to download my emails (for the bizarre reason that this software actually start to work better in the last ten days) but I have removed all the software in an effort to sort this problem but to no effect. I also removed the peripherals, in this case an Apple CD-ROM and my Seagate backup disk but to no effect. Then yesterday when the Mac woke up after 'sleeping,' my desktop was rearranged and all my folders, etc were on the main Mac screen and not second screen, which woke up normally with the rest of the kit. I manually arranged things back to where they belonged and they have stayed through further boot-ups. I looked in Diagnosic Reports and can not discern what the problem is, although I do see 'should repair' being mentioned. So here is a bit of the most recent report in case it helps.
