 While trying to test Snowflake on a macOS 10.9 system (for #26251), I
 encountered a different issue: tor.real fails to start. The error is:
 {{{
 dyld: lazy symbol binding failed: Symbol not found: _mach_approximate_time
   Referenced from: /Users/.../Desktop/Tor/TB nightly 2018-07-18/Tor
 Browser.app/Contents/MacOS/Tor/tor.real
   Expected in: /usr/lib/libSystem.B.dylib
 }}}

 At this point I don't know if this is a core tor bug or if it is caused by
 something in the Tor Browser 8.x build process.
