Is McAfee Security for your devices any good ? Has anyone had any trouble with it ?

Do NOT install McAfee! Anti-virus and other cleaners have no place on a Mac. They cause performance issues, cause security issues, and makes macOS appear buggy. macOS has built-in security:

• macOS - Security - Apple
• Protecting against malware in macOS - Apple Support

Uninstalling McAfee is problematic and is part of the reason anti-virus app shouldn’t be installed.

This link describes removal from a Mac. I’ve never needed to use it so I can’t validate it. There are other methods to be found but do not install any cleanup apps if told to do so.
