I am trying to notarise a .dmg of my desktop application, but the process seems to just hang on 'In Progress'. It's not actually hanging, as I accumulate extra '.', but clearly it isn't working.
This exact same codebase notarised fine recently. The only change has been a downgrade in OS from Monterey to Big Sur. I appreciate this is unusual, but I am required to support my client, who is running a 2013 MacBook Pro with Big Sur.
I appreciate that some of these tools are newer than Big Sur, but surely it should work?
