Remove update prompt?

[mikerofoto]

nothing so far, un-install from Nik uninstaller and downloading/install latest version from your account still bring the same issue.

Nik 3 download update

I understand your frustration, especially since most of us are not having that problem. I’m not a Mac person, but did you try uninstalling, and then reinstalling the Nik Collection after making sure that all folders related to it were removed? On Windows there are sometimes hidden folders that are left behind after an uninstall. Mark
