Thanks; I removed GMT, found a “GMT” folder from 2017 in my Applications, and removed that too.
Rebooted in “Safe mode”, and logged in in “Safe mode”. That usually cleans out leftover issues and problems.
Downloaded the MacOS x86 version again, and installed. Got the pop-up of refusal from Apple, went to “Security and Privacy”, clicked on “Open anyway”. Nothing happened. That pop-up only shows up on the first opening, then not again.
Typed in “get --version” and got:
andrewlazarewicz@FantasyReef ~ % gmt
zsh: command not found: gmt
andrewlazarewicz@FantasyReef ~ % which gmt
gmt not found
Used terminal to get into “/Applications/GMT-6.2.0.app”, dug down a bit and got:

Yes, I agree that Apple is overly paranoid, and usually “Open anyway” does work. It seems as though Apple blocked GMT from my PATH. I’ll rummage around and see if I can figure it out. But this may be a local problem, as other users don’t seem to complain much about this.
Thank you! - Andy
