It has come to our attention that upgrading to MacOS Sierra (10.12) may cause a problem with Adobe Creative Cloud applications. It is possible that the Adobe products in some cases may not function after the upgrade and that we may not be able to reinstall the software at the current time. We are working to determine a solution but suggest that anyone who is using or may need to use Adobe Creative Cloud applications on their Mac not upgrade to Sierra at this time. Though some of the software in the package may continue to function, other programs within the package can be individually affected and may not run properly or at all.
We will post updates when they are available.
