#macOS Tahoe only has 3 new shell commands over Sequoia as far as I can tell:
1. avbcapture "Audio Video Bridging traffic capture tool"
2. lesskey, a command from `less` which appears to have been deprecated before it was even added
3. memacct, no man page, --help says "Monitor memory accounting of various subsystems". Not entirely clear what it's for.
Overall pretty dull for CLI folks.
BUT…
