Saw an earlier post about "how to uninstall the Opera app on Mac". The usual methods not working. So I figured I'd share how I accomplished it. After first trying in Launchpad to click and hold, the button to uninstall did not show like some system apps. Then launched Finder and was disappointed to find it was not listed. No worries, at the top right, do a search for "Opera" under Applications, and it will show up for you to click and hold, then move to trash. After that empty the trash, and restart.
Interesting and good work.
Also, interesting is posting in Yosemite OS X 10.10 about this issue though user profile indicated running Monterey macOS 12.1 which is Beta Software.
Yosemite OS X was the Topic I was responding to.
