Thanks for your quick reply! Unfortunately, I couldn't open the ADFMaster3.app (MacBook Pro, Intel, 2020, Sonoma 14.3.1).
Hmmm, does it work when holding CTRL + Right Click on app -> Open ?
It says: "Du kannst das Programm „ADFMaster3“ nicht öffnen, da dieses Programm auf diesem Mac nicht unterstützt wird. " The logo is crossed out too...
Ah, try again... Build was not universal.
It does work now! Thanks :)
