I just spent 20 minutes attempting to figure out how to install an SSH Server on Mac OS X (10.6.2). Turns out it was pretty much a waste of time, because it was already installed, it just needed turned on. I figure I will make a note of this in case anyone else tries to do it and also struggles. Maybe it’s only me that didn’t realise this at first.

Go to System Preferences, Sharing, then check the “Remote Login” box. Job done.
