I have Topaz Photo AI 3.2.1. I also have a Mac Studio running Sequoia 15.0. I am able to export an image from photos and edit it in Topaz Photo AI. However when I select “Export to Apple Photos” it gets hung up. The image never makes it back to my Photos app. It just keeps spinning.
Disable any antivirus, firewall, VPN, or proxy software that might be active on your computer. These tools sometimes interfere with the installer’s ability to download the model files.
Ensure that the Topaz Photo AI installer has all the proper settings in your system by going to your Mac System Settings > Privacy & Security tab and scrolling down to the security section. You will want to make sure you have ‘App Store and identified developers’ selected | MacOS | Example of Proper System Preferences
