can't get it installed on my mac. the site doesn't have any good information on it, i had great expectations about it when i switched to mac, but it failed a little :(
it is really fast and uses amazingly few resources, includes everything i need. Great player
Since I am on Ubuntu I cannot run iTunes easily... So this has been a good alternative.
