I’m still running Mac OS X 10.3 Panther or older. Can I use MobileMe?
Most MobileMe features will not work on Mac OS X versions older than 10.4 Tiger. This is due to the fact that MobileMe incorporates new technologies and capabilities that came along after these OS versions were created. However, some functions will continue to work, including: ▪ Email using Mac OS X Mail ▪ Using iDisk in the Finder ▪ Publishing from iWeb 1.
