After upgrading to Mountain Lion, I found that Contribute CS4 did not open. In searching for an answer I found the following on the Adobe forum:
"Earlier versions of Adobe Photoshop (CS3 and CS4) software were also tested with Mountain Lion and there are currently no known issues."
So continuing to search, two days of frustration ensued as I "chatted" with 2 unhelpful Adobe customer support reps, searched unhelpful Apple and Adobe websites and posted my question in various places. Finally I found that the above statement was completely wrong when I received the following from an Adobe staffer:
Mountain LION is not a supported platform for Adobe Contribute CS4. The supported versions are Latest Adobe Contribute 6.5 and Adobe Contribute CS5.X.
And now I have to spend hundreds in order to maintain my website after upgrading to Mountain Lion. I don't even know to whom I should take my complaint, Apple or Adobe. Does this mean I have to research every piece of software I use before upgrading my Mac? At the very least, Mac owners should be forwarned of platform support failures for major 3rd party producers. I'm doing my bit here. How about you taking some responsibility?
