Unfortunetaly I've updated already to macOS Catalina 10.15 and cannot work with the Captivate Release 2019 (Update 3). What date is "End of Fall 2019"?
That would likely be the end of November or thereabouts. You have a long several weeks wait ahead of you unless you are prepared to roll back to the earlier OS version.
I have now temporarily installed Captivate on Windows to continue working. I would like Adobe to inform me about such critical circumstances in advance, e.g. by eMail.
Are you also going to ask the same of Apple? It was their update to the OS that did this. Captivate had not changed.
Really? If you had checked the release notes for CP2019 you should have known that this version was NOT compatible with new OSs. Totally agree with the comment of Rod. It seems that Windows users are more careful with installing new OS without checking out compatibiity....
Other apps from major manufacturers will be updated in time.
Patch to make Captivate 11.5 compatible with Catalina OS should be available,.
Have a look at this announcement by the team:
