macOS Sierra Finder complains that 'tor' isn't signed
I have a macOS user with permissions set to allow apps downloaded from 'App Store and identified developers'.
This user is also a 'Parental Controls' account, which means each executable is checked separately on open.
When I open Tor Browser, I get a message saying that tor (which on macOS is a shell script) is not signed. This seems to go away after the app is approved via parental controls.
(There might not be anything we can do to fix this issue.)
