So one week after moving to a new Mac everything is working well. So far I’ve managed to avoid needing to use any apps that would rely upon Rosetta 2 to function.
The one that really hurst is ScanSnap, because it’s only three years since I bought my Fujitsu iX1500 and I’m not sure how long it will be supported.
The other app I miss as part of my photography workflow is Photo Mechanic.
