I just upgraded to a new Macbook Pro M3 with Sonoma 14.5. UA Apollo X4 DOES NOT WORK! I followed all of the instructions to uninstall/re-install:
https://help.uaudio.com/hc/en-us/articles/360051069691-UAD-Uninstall-Reinstall-Procedure-macOS
I then followed all of the instructions for Apple Silicon Mac settings:
https://help.uaudio.com/hc/en-us/articles/360057137692-Apple-Silicon-Compatibility-with-Universal-Audio-Devices
I also followed the install instructions for Sonoma 14:
https://help.uaudio.com/hc/en-us/articles/19237390771860-UAD-Software-Compatibility-with-macOS-Sonoma-14
After installing, restarting and then going to System Settings/Privacy & Security and scrolling down to Security, there is no dialog box "System software from developer 'Universal Audio' has been updated" and there is no button to "Allow". After 30 minutes, I get an error message saying, "...Universal Audio application not authenticated".
I've uninstalled and reinstalled several times just to make sure I followed directions exactly, still no luck.
Going to return UA Apollo X4 and replace with another brand to see if I'll have success...UPDATE SOON!
