Problem - iMac found problem and restart itself when switching between users

[onair125]

Late 2015 iMac.

I've noticed when switching between users, I get error message (most of the time) that 'Computer has found problem and need to restart'..so it auto restart.

Anyone know the solution for this?

Late 2015 iMac. - Top of the line specs.

Thank you in advance.

Sounds like a kernel panic and that typically occurs with a hardware fault. I'd take a look at the logs in the console app, and see if there's anything that jumps out.

Also if you can cause this issue to occur regularly, disconnect all devices, other then the keyboard and mouse and see if it continues.

Back up your data and reinstall OS X as a clean install, i.e., reformat your drive. See if that fixes the issue.

Finally failing that, and again, if you can easily reproduce the issue, then call Apple
