I have a working prototype of a notarized version of #OmegaT.app for #macOS packaged in a signed standard dmg volume. Both open nicely on 2 different #Sequoia machines that I tried them on.
The document where I describe the process is here:

The prototype is here:

Thank you @amake for your #macport version of OmegaT. I used its launcher script to fix our "can’t launch the JRE" issue.
