I DO very much appreciate the swift effort at attempting to help...but that is NOT a working resolution for me.
1) As I was very clear on in my OP and title, I am seeking assistance with uninstalling Adobe Digital Editions 3 (for Mac)...
2) BECAUSE Adobe is distributing this software as an "installer", I am not even going to begin to trust simply deleting the Adobe Digital Editions 3 app from my applications folder...no way! I want to thoroughly remove ALL TRACES of this application (EVERYTHING that was installed by the installer, or later by the application itself, onto my computer. Simply deleting the app fro my my applications folder will NOT be sufficient to achieve this goal.
3) As the name would suggest (and the step-by-step instructions would collaborate, the CC Cleaner Tool is only for Creative Cloud installation and removal problems (and to the very best of my knowledge, Adobe Digital Editions is certainly NOT a CC program.)
"A" for effort, but not so much on providing a relevant/working Adobe Digital Editions 3 (for Mac OS) uninstall/removal suggestion(s)...STILL looking for a working solution!
