Question marked as
If that Intel version of Digital Editions 4.5.12 was ever compatible under Rosetta 2 on Apple Silicon, it may work on macOS 27. Rosetta 2 goes away for Intel applications in macOS 28 in Fall 2027.
Adobe is entirely responsible for their own business and application development decisions. Apple provides the software developer kits, and that is the extent of Apple's involvement.
Contact Adobe for their intended commitment for Digital Editions.
