Whoaaaaa, what does this mean?
In the man page for `screencapture(1)` (on macOS), it says this:
> To capture screen content while logged in via ssh, you must launch screencapture in the same mach bootstrap hierarchy as loginwindow:
> PID=pid of loginwindow
> sudo launchctl bsexec $PID screencapture [options]
Wtf is a mach bootstrap hierachy? Apparently it's something related to `launchctl bsexec`?
Something to research! A thread to pull!
