> Apple could not verify “whosthere” is free of malware that may harm your Mac or compromise your privacy.
Couldn't run it on macOS Tahoe. I believe this requires me lowering the security to allow it, which is something I would rather not doing.
this can be fixed by
xattr -c `which whosthere`
This is basically how every custom app works on Mac. You have to go to Settings -> Security & Privacy and click "Allow whosthere"
