Adobe. Make It an Experience.Tim commented
The BETA does not resolve the issue of the message "This file has been modified outside of Illustrator". I just installed it and the problem showed up immediately. This is truly annoying. If it is related to the latest Mac OS update, then it would be good to know that for sure. So far, Apple seems to think it is an Adobe problem. It only shows up in Illustrator, at least in my experience so far.
