My iMac 27" 2019 (Big Sur 11.7.6) is randomly shutting down and restarting. I do not have it set up to automatically update software. I have auto back up to Carbonite, and I just backed up additionally to Dropbox, so I don't think I'll lose any data if it crashes. I just can figure out why it keeps shutting down. Any advice or thoughts on this issue???

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...
