title: XCode - unable to create snapshot - don't want git
body: <p>After several successfully done "create snapshot"s, XCode now tells me it is "unable to create a snapshot" "please tell me who you are"... and some stuff about git.
  i never used git and don't want to, but i need to create snapshots...
  Do you know how to manage this?</p>
