You can install Unison on the Mac via homebrew (brew install unison), but it's very likely that it won't work properly, resulting in errors like:

Unison failed: Uncaught exception Failure("input_value: bad bigarray kind")
Fatal error: Lost connection with the server

How to use Spotify in any country

If you can put up with ads, you can easily trick Spotify and sign up for an account, even if you're not in one of the supported countries. You'll need:

• A Facebook account
• SSH access to a server based in one of the supported countries (US, UK, whatevs).

First, set up an SSH tunnel, as described here: http://paulstamatiou.com/how-to-surf-securely-with-ssh-tunnel
