I’ve posted previously about XBMC which is currently the best media center available on the market. The only problem is it runs on the old original xbox and it doesn’t support 720p or 1080p. Recently though a Mac version of the software got released and its turning out to be exactly like the Xbox version (which is a good thing) except that it plays 720p/1080p movies flawlessly. I’ve been playing around with it for two weeks now and the progress thats being made in such a short time is ridiculous. The fact that they manage to make XBMC even more responsive then the already fast xbox version is unbelievable and the specs needed to run it are very low. I am running it on my 1.8ghz core duo MacBook for example and streaming 720p movies over Wifi without a hitch.
If you have an Intel Mac download the software and try it. You just drag and drop the app onto your desktop and run it. Here is a link to the website. [Link]
