Mogan v1.2.9-rc6: last RC and need your help on feedbacks

https://github.com/XmacsLabs/mogan/releases/tag/v1.2.9-rc6

I will release v1.2.9 LTS about 24 hours later. Need your help to make Mogan STEM Suite v1.2.9 LTS the best one with less bugs.

Maybe add instructions for running it on macOS Sequoia in a prominent README?

MacOS Sequoia’s security makes it more difficult to run than in earlier versions of macOS.
