@NanoSector That’s the status bar in iTerm2. I honestly don’t remember how to enable it, but if you go to Preferences > Appearance > General, its location can be set with “Status bar location,” and then, if you right click on the status bar, it presents you with a context menu with options to configure its colors and what pieces of information it shows.
@Synchro It exists, but it’s the macOS stub at /usr/bin/m4.
I also have it installed via Homebrew, so I’ve added that to my PATH temporarily, so I can build something. I’m not sure what’s up with /usr/bin/m4, though. I’ve re-installed the XCode tools, rebooted my laptop, etc. /usr/bin/m4 still gives me that message, though.
@ramsey Ah, sorry. I did as well but mine went missing in the upgrade and I had to reinstall. I got the same nonsense message about Software Update but that flow didn't work until after I upgraded the dev tools.
