I received the following

The macOS 12 runner image will be removed by December 3rd, 2024. To raise awareness of the upcoming removal, jobs using macOS 12 will temporarily fail during scheduled time periods defined below:

November 4, 9:00 AM - 7:00 PM EST
November 11, 9:00 AM - 7:00 PM EST
November 18, 9:00 AM - 7:00 PM EST
November 25, 9:00 AM - 7:00 PM EST
What you need to do

Jobs using the macos-12 YAML workflow label should be updated to macos-15, macos-14, macos-13, or macos-latest. You can always get up-to-date information on our tools by reading about the software in the runner images repository. Please contact GitHub Support if you run into any problems or need help.

If we are fixing the packaging we might use the opportunity to bump the configuration to use a supported OS runner

This PR is actually redundant anyway. We want to provide .app rather than .dmg for ease of signing but upload-artifact will nuke any symlinks within the .app and destroy it if we upload it this way. Will need to redo this.

Moving off of macos-12 is problematic because some of the tools used really don't like 13, but will investigate.
