For the past week, I keep getting this error message saying there was a problem when the computer shut down.
There was no problem setting it down.
Running on Monterey 12.6.6
Imac 4k retina late 2015
How can i stop this error message please?
iMac 21.5″, macOS 12.6
Hi,
I suspect this is real macOS error message, though force shutdown, then startup in Safe Mode, then normal boot could solve your problem.
You should contact Apple Support to tell them about your error message as well.
Start up your Mac in safe mode - Apple Support
Disconnect all external devices in case one of them is causing a problem.
Before selecting "Shutdown", press the Caps Lock key so its LED is lit. Then perform a shutdown of the iMac. Make sure the Caps Lock LED goes out to indicate the computer is completely powered down.
Are you running any anti-virus apps, cleaning/optimizer apps, or third party security software, or even bittorrent/file sharing software which may not be allowing the computer to shutdown cleanly?
Edit: Also try a PRAM Reset (hold for at least three chimes, need to use a wired USB keyboard) and possibly an SMC Reset.
Try running the Apple Diagnostics to see if any hardware issues are detected.
Hello,
We need to see what all is running & machine specs, a report from this will not display any personal info...
EtreCheck is a FREE simple little diagnostic tool to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac. It will not display any personal info.
Pastebin is a good place to paste the whole report if you capture the URL while there…
Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck. In a Reply before you click post, look for this to add longer texts...

Has happened to me too. I just cut to the chase and reinstalled the OS. Problem solved.
Thanks for reply.
Been in safe mode, logged out of safe mode and logged in normal mode and message came straight back up.
OK, thanks
I am a novice at things like this so what would I have to do to remove and reinstall it?
Would it affect all the other things running on my IMAC? e.g. Lightroom, Printer set ups?
reinstalled Monterey but the error message still comes up.
can't upgrade to Ventura.
Shut down error message
