I received a Joost invitation recently. Just today I tried to install it and check out the new video streaming service. So I click on the email link, go to the site, and then start downloading. It’s a big file, over 30 MB. Since I am a new Mac user, I had to figure out how to install something. As far as I can tell, you download a .dmg file, mount it as a drive, open it, and then drag the application over to the Applications folder to install. You can then eject the mounted drive and you’re all set. When I clicked on Joost to open the program, I got a prompt that tells me that Joos only works with Intel-based Macs. Crap.
