Hello everyone.
I'm having trouble installing Subsurface-6.0.5597-CICD-on macOS Tahoe 26.4.1 (25E253). The application isn't signed.
Entering my administrator credentials doesn't change anything; the application still won't install.

Using your preferred search engine will literally yield thousands of pages with the same set of instructions.
And of course the search function in this forum would do the same.
