Stuck on Starting XBMC

Ah yes: Always unmount - as this syncs the data and allows a safe removal.

The easiest way is, from terminal.

ssh xbian@192.168.x.xx IP of your mac.
password: raspberry

sudo nano /etc/apt/sources.list (Remove # from stageing line.)
<cntl> o to write the changes, <cntl> x to exit nano.
sudo apt-get clean
sudo apt-get update
sudo xbian-config (and follow the prompts there)
