MacOS Catalina 32bit Question

[pjglad]

I recently did a clean install of macOS Mojave in August then installed Photoshop CC 2019, DNG Converter, Acrobat and Flash. Today, I ran a System Report and I have several Adobe applications that are 32 bit. Why is that? Will that be an issue when I install MacOS Catalina which does not support 32 bit apps.

Photoshop CC 2019 has not been tested on MAC Catalina, so install it at your own peril, people who have upgraded to the new MAC OS are experiencing issues with most Adobe apps

There will most likely be a Photoshop 2020 for Catalina, just as 2019 came out for Mojave.

Expect initial problems, and don't update anything until the dust settles.

I'm confused. Adobe has known for years that 32 bit apps will not work with Catalina. As I said I did a Clean Mojave install in August and then installed Photoshop CC 2019, DNG Converter, Acrobat and Flash Player. Why is Adobe still shipping 32 bit apps when they know categorically that they will not work?

We're all aware of the equation and what's at stake - including Adobe.

It's a matter of being patient and not being an instant adopter of Catalina.

Adobe is unlikely to finalise their 64 bit components until they've got a final Gold release of Catalina. Anything released earlier may break given that Apple tinkers with its code until the last second.

What's to be confused about? It's a job that needs to be done, and they are doing it as we speak. It takes a certain amount of time. It's a little more than a snap of the fingers.

It'll be there when it's needed, stop worrying.

MUCH more is changed in Catalina than 32 vs 64 bit. That's just the only bit journalists understand. Don't expect ANY app to work. Wait for news, or join the queue of people who jump on the first day and find themselves in very hot water... we always hear from lots of them for each new Mac OS.

Adobe has a web page listing the 64-bit status of its macOS applications:

https://helpx.adobe.com/x-productkb/global/fix-macos-64-bit-compatibility-errors.html

Some of the components you listed might be from older versions than the one on that list. For example, Adobe hasn't sold Flash for a while now. The only application listed in the Creative Cloud desktop app is Flash Builder.

For current Creative Cloud applications, the installer, updater, and licensing components are rolled into the Creative Cloud desktop app. They generally no longer use the components shown as not 64-bit in the list.

Thank you for your response. I did some research and yes all these 32bit apps are Flash related. I just uninstalled Flash and the Adobe Application Manager Folder and BINGO.
