They aren't that bad once you get past the learning curve and get over losing the Adobe interface. And Catalina is totally 64-bit only, so either start coughing up monthly rent to Adobe, which I'll do when hell freezes over, or do what I've done: find open source alternatives. I think I was still able to use Acrobat for some reason, but my memory could be faulty on that. When I installed Mojave on both my iMac and 2012 i7 MBP, Creative Suite wouldn't work any longer due to 32-bit issues. Any ideas?Ĭlick to expand.I have to assume since Apple 'steered' you straight to Catalina, your previous OS was High Sierra or earlier, having skipped Mojave. What could be wrong? Wondered about the memory, the harddrive has about 500GB of space, and the iMac has two 4-GB RAM chips (?). One cant sit waiting 23 seconds to switch between tabs on Chrome, or 17 seconds for an email to open. But basically, the computer is running like its in quicksand - essentially unusable. In addition, none of my old apps work with the new O/S so I lost all my Adobe Creative Suite, MS Office, and others. My Mail app said something like it had been wrecked and i had to re-install it or something(?), and so then it set about downloading 78000 emails. And when it was finally complete, so many things seemed screwed up. So i do that yesterday, but it starts taking forever. So i try to upgrade the O/S and Apple steers me straight to Catalina. Tried to upgrade Acrobat, but turns out my O/S is too old for Acrobat 2020. I suspect that my old Acrobat Pro (2008) was simply too old to open this file by a newer Acrobat. So, now the problem looks like on my end.

? A week later i receive another pdf from a different source, and same error message. But the guy said he'd only protected against edits. assumed the file was the problem - had been protected or similar. Brief history: a week ago i received a pdf that would not open. Just upgraded to Catalina y'day and its been a disaster.
