The biggest problems with compatibility and stability were with the first release of El Capitan (OS X 10.11.0) many of those problems were fixed in OS X 10.11.1. Here’s what I know so far about the state of Adobe software in El Capitan. Upgrading to El Capitan seems to go relatively smoothly for most software.
With OS X 10.11 El Capitan now available as a free download from the Mac App Store, you’re probably wondering how well your Adobe software and other Mac apps will run on it.
