 Fresh install of Tor Browser following the download of the latest version
 of Tor Browser from the official website (with signature confirmed).
 Removed ALL previous directory related to Tor so this really is a fresh
 start as much fresh as "find" command cannot find any mention of
 TorBrowser on the hard drive.

 PS: same behaviour with latest version of Tor Browser following the
 upgrade to Mac Sierra (hence the reason I think this is a problem on Mac
 Sierra and not Tor itself).

 Install tor and configure obfuscation 4
 Start tor
 (so far so good most of the time)
 Try to access ANY tor website
 Browse it for a while.
 Suddenly, no more connection at all
 Need to stop Tor Browser and start a new Tor Browser (from scratch, not a
 new window) to retrieve some connection.
 Repeat
 Cry
