Hi @AlvinaLa1 , this is a known issue that Adobe engineering is aware of and actively working on.
The warning appears on M-series (Apple silicon) Macs because the Desktop Proofing Viewer is currently Intel-based and runs through Rosetta on those machines. Based on Apple's documentation, this warning relates to a future macOS version (macOS 28) which is not expected until mid-2027, so there is no immediate disruption. I’ve checked internally and confirmed that they are working on a native Apple silicon build of the Desktop Proofing Viewer. There will be two separate builds, one for ARM Macs and one for Intel/Windows. The documentation will be updated once this is released. No public timeline has been shared yet.
In the meantime, the Adobe Workfront Review browser extension is designed as a replacement for the Desktop Viewer for interactive proofs and works across all browsers and operating systems without any platform dependency. If your users are open to it, this is the cleanest workaround while the native Apple silicon build is being developed.
