Hello, did you test Xcode?

 

[Technomad]

Nice job. +1 on Xcode, and do you need to patch to run Adobe CS?

Certain Apps working/not working has nothing to do with individual builds. Xcode does mostly work on AMD except for Watch Simulator. Adobe needs patching for all AMD CPU unless you use Virtualization.
