At this time, Fender FUSE is not fully compatible with Mac OS X (10.7) Lion. We are actively testing Fender FUSE with this Apple OS and will announce full compatibilty as soon as possible. Currently, users who have either purchased new Apple computers or upgraded their current systems to OS 10.7 Lion can run Fender FUSE on those systems with the following limitations:
● Users will need to log into their Fender FUSE Community account on the Fender FUSE Community home page directly
https://fuse.fender.com/ rather than logging in inside the Fender FUSE application.
● When going to the Fender FUSE Community website through the Fender FUSE software, the website does not render correctly at times. The Fender FUSE Community website is fully functional when logging in through the respective OS Browser (Internet Explorer with Windows & Safari with Mac).
