Hi Monica, Previous to High Sierra I was able to double click on a psd, or ai and have the correlating app open. Now the same action opens preview only. YES, I have done the "get info", Control Click, and clicked the change all multiple times. I have been told by a Facebook friend that It is possible that Firefox is the issue, I am not familiar with Mac OS Launch Services Database, or what you are referring to. If the issue is Firefox, that seems odd to me since I am working on my desktop, in my studio, not online, not in a network or anyplace where there would be a conflict in administrator of Users and Groups. This is a home studio using Creative Cloud. Can you please expand upon what I need to do to get the apps to open when the icons are double clicked - while using Firefox as my browser? I still don't see the relation between my web browser and the desktop apps. You kind help is appreciated.
