What version of Acrobat to install on new MacBook Air

@normharris3 let me get this straight here,  you have Adobe Acrobat Pro 2020 was originally designed for Intel-based Macs. When you run an Intel-based application on an Apple M-series (like your M2 Pro and M2 Air) Mac, macOS uses a translation layer called Rosetta (not just "Rosetta" from the PowerPC days) to allow the application to run. Rosetta works incredibly well and is essentially invisible to the user most of the time. So, even though you have an M2 Mac, your Acrobat Pro 2020 "Classic" version is indeed running via Rosetta, which is why it works on your Mac mini without you needing to explicitly install anything – macOS handles it behind the scenes for apps that require it.

The question is what plan should you get? Honestly, I would see if you can still run 'Adobe Acrobat Pro 2020' on the new Macs—it's a slight work-around. If it doesn't work, then you need to upgrade to a subscription. 

On your new MacBook Air, try to manually install Rosetta. You can often do this by opening Terminal (use Spotlight search or find it in Applications > Utilities) and typing the following command, then pressing Enter and following any prompts: softwareupdate --install-rosetta

Type A to agree to the license, then press Enter again. That’s it! Once installed, Rosetta 2 works silently in the background—no need to manage it through Adobe or any other app. Once it's installed, try running the Acrobat 2020 installer again. It should now proceed without the Rosetta error.
