Caution:
With the Big Sur 11.0.1 update, the drivers of a few printers have become incompatible. As a result, printers may stop working, and printing from any application may cause an unexpected error.
We recommend users to download and install the latest printer driver from the printer manufacturer’s websites to resolve this problem.
Acrobat Reader DC, Acrobat DC, Acrobat 2020, and Acrobat 2017 are compatible with macOS Big Sur (version 11).
When does Adobe plan to natively support Apple Silicon devices?
We are working to ensure that our apps are natively compatible with Apple Silicon devices, but do not have a release date yet. Apple Silicon devices ships with Rosetta 2, an emulator that enables ARM Macs to run Intel-based apps. Acrobat and Acrobat Reader will work on Rosetta 2 until they are available natively.
Acrobat and Acrobat Reader will run under Rosetta 2 emulation mode on Apple devices with M1 processors running macOS Big Sur. You may want to remain on your current macOS version or test in a non-production partition to ensure all your software and hardware is compatible.
