MacOS Big Sur

Has anybody tested Topaz apps with MacOS Big Sur?

A mounth ago I had Big Sur and I hadn’t problem with Topaz programs.

I’m experiencing problems with the installer / updated process. Essentially a file permission problem - every Topaz product on Big Sur. Happens with both the web and full installer when installing / updating files. Big Sur public betas 7/8/9. I’m experiencing this with an administrator account. Error messages like

“Error chasing permissions to 040755 in /Applications/Topaz Labs LLC/Topaz Sharpen AI/Topaz Sharpen AI.app”

are characteristic.

Invoking the installer from the terminal window as root functions as a workaround but this isn’t really practical.

Adjust AI doesn’t work on Big Sur. All the other products work on my computer with Big Sur without any issue.
I’m running BIGSUR on a new iMac 2020.
After contacting the support they confirm it doesn’t work with Big Sur yet.
