Thanks. I only have one profile in my Profiles. It's from Comcast, my US Internet provider, for automatic connection to their wi-fi network (which usually is useless). Should I remove it? I can always reinstall it when I'm back in the US.
You don't need to use any software from Comcast (or usually any other ISP) to access the Internet or your ISP email. There may be some exceptions with some ISPs, but generally the ISPs software is not needed. Always question the need to install third party software.
As for removing the Profile, you may need to run the uninstaller app/utility for the Comcast software. Sometimes the uninstaller may be hidden within the vendor's folder, or within the app bundle for their software. Usually it is best to check with the developer (in the case Comcast) on how to properly uninstall the Comcast software and MDM Profile.
As for your failed attempts to remove the Profile, what happens after you enter your admin user name & password? If there are any error messages, please provide them. I won't be able to assist much more with this issue since I am not a macOS software expert.
