Some hard to find tips that are a bit old (tested on OS X Lion), but most of them still work: https://software.clapper.org/cheat-sheets/mac-os-x.html https://software.clapper.org/cheat-sheets/mac-os-x.html For me, an immediately useful tip was hiding user login for Git user.

Be sure that you are behind NAT or a firewall so as not to expose the web UI to internet!
