This "obsolete" MP runs fine, but the EtreCheck report shows some things I don't understand.
I plan to review the unsigned files and uninstall old cruft.
Thanks in advance for your help.
And a big thank you to Limnos, who pointed me to EtreCheck in a 2019 post.

You have some third party software installed with which I am unfamiliar so other more knowledgeable contributors will need to comment on the third party software since I am not a macOS software expert.
If you have issues with the "sudoers" file, then either you or some third party app/utility has made an improper change to the file. Post a copy of the "sudoers" file here using the "Additional Text" icon which looks like a piece of paper. You need to copy & paste the contents of the file since dragging & dropping files does not work on these forums. I'm not an expert on the "sudoers" file, but a standard user does not need to be listed in it AFAIK unless it is a macOS thing. Perhaps it indicates an incorrect entry in the file. The is only supposed to be modified by using the "visudo" command on the command line since this utility actually checks the integrity of the file when saving modifications.
FYI, if you need to make changes to the "sudoers" file it is much better and safer to create a new file within "/etc/sudoers.d" folder with the changes you want so you don't actually destroy the main "sudoers" file. I can provide instructions if interested.
You can run the Apple Diagnostics to see if any hardware issues are detected.
