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 ship with Rosetta 2, an emulator that enables ARM Macs to run Intel-based apps. InDeisgn will work on Rosetta 2 until they are available natively.
There are no known issues specific to running InDesign under Rosetta 2 emulation mode on Apple devices with M1 processors running BigSur (macOS 11).
