15.8 won't drop until September, at the same time as macOS 27. In the meantime, they will continue offering 15.7.x releases.
I tried the Seq. Beta route after 15.7.6 had been released; Tahoe and the Badge disappeared for about 3 days but 15.7.6 is now showing; it doesn't indicate whether it's a Beta or RC so that adds another issue; having to check whether it's some kind of urgent update that went straight from a Beta to a Public release. I didn't power off the device or search in Software updates so it looks like it was some kind of routine Mac maintenace type of search that caused it.
Bogdanw answered that in Post # 26 of this thread. The Terminal command in Post #3 gets rid of the Tahoe badgering, but the 15.7.6 RC (and further Sequoia updates) will appear, with that Post #3 Terminal command alone.
I failed to mention that I was using OCLP; thus every update is in effect like a full OS install, so not desirable for every Beta/RC - the numbers of which seem to be increasing. Will leave it on the non - developer Beta channel to avoid Tahoe notifications.
Probably so. Although I haven't enabled Beta Updates in System Settings. It probably is going along the terminal script.
Is that Developer full installer link for Sequoia 15.7.8 as stated above? That must be a typo, and you meant 15.7.6?

main "$@"Since macOS Big Sur, Apple has included the links for the macOS full installers (InstallAssistant.pkg) into the seed catalogs, the links where macOS looks for updates.
You can't download beta installers from the App Store.
15.7.6 is official
It is not. If you have it installed, you have a pre-release version that came from the Sequoia beta channel. (If you used the terminal command from earlier in this thread, you have put your Mac on the beta channel.) There is no indication that it is a "beta" or "release candidate" if you check "About this Mac" or Settings or whatever (this is normal), but it is a virtual certainty that there will be additional 15.7.6 pre-release builds made available before the final release drops alongside Tahoe 26.5 in mid-May.

</plist>I’m not in the beta program, this is something I would have liked to do but I don’t have the pref for Beta in my System settings . This is why I eliminated all my profiles because I thought this could be the reason. Then I installed just the profile to stop Tahoe.
