Do we need antivirus for Mac

There are no known Viruses in the wild that self replicate and affect macOS. There are Malware and Adware that does affect macOS and are often times downloaded as part of an Application from Third Party UnTrusted Site and get installed along with the Application.

And for that purpose - use the suggest software from previous poster.

Oh and Profile is showing macOS 12 - that is Beta - is that correct.

macOS already contains Anti-Virus called XProtect. You need no other.
