For those of you who don't know, Fluid basically grabs a web app (like Facebook) and saves it as a "Real Mac App" on your computer. And unlike running in your browser, it's blazing fast. iCloud is horrifically slow on my G5, though it does work. That's using TenFourFox. I figured that I could make a Fluid app of it - but when I launch the app, iCloud says that my browser is not supported. I've tried changing the user agent in the iCloud.app created by Fluid but to no avail. Tried custom user agent strings for Safari 6, still no luck. Any ideas?
