Adobe and Apple have worked closely together to test Adobe Creative Cloud applications for reliability, performance, and user experience when installed on Intel-based systems running Mac OS X El Capitan (version 10.11). The latest versions of all Creative Cloud products are compatible.
Is Adobe aware of any issues, bugs, or odd user experiences when using Creative Cloud or Adobe Acrobat® products with OS X El Capitan?
We are aware of some issues that users may experience after upgrading to OS X El Capitan (10.11). We are working hard to resolve these issues in a forthcoming release and we currently recommend users upgrade to the latest version of OS X (10.11.1) or remain on OS X 10.10.x.
