> Macs do not allow running unsigned software by default, and no one runs antivirus on Mac, ever.

My company-issued MBP is running something called "Cylance Protect" (and "TrendMicro" earlier). And also something called "Forecpoint DLP". I have no control over any of that, software just appears and disappears. I think it's done by something called "Jamf".

I don't really care either way. The only thing I actually use on the Mac is Chrome for email/calendaring/vidconf and some intranet sites. Actual work is all on Linux servers via ssh (and even that has "ClamAV" antivirus running). So I'm just using it as an expensive terminal/chromebook.
