MP 1,1-5,1 Monterey shown in software update on 5,1?!

I know that official support for the 5,1 ended with Mojave. But today the software update control panel shows Monterey. Why? It never displayed Catalina or Big Sur as available updates. Does anyone have an idea what is going on here?

Doesn't show up here.
I know when MacOS installs used to be in the App Store, they would show with an upgrade button and 'works on this mac', even though it doesn't.
Do you have open core installed?

Yes, I’ve had OpenCore installed for a few weeks. However, Big Sur never showed up.

You needed to change the VMM flag in order to allow the updates to be displayed.

After a little research I found out that turning on the VMM flag is a parameter change in OC to show OS updates. Funny thing is I did not touch my OC configuration, hence my surprise and confusion. It's not a big deal, though. Maybe I will update to Monterey once there's a safe and easy route.

It's not that simple. If you run a benchmark for comparision. For example: Geekbench. With VMM turned on. The CPU score is lower. When it's off. The CPU score is higher. The different is about 5-10 percent. I upgraded to Big Surf 11.16.1 since yesterday and now I have it turned off for better CPU performance and VMM is useless to Big Surf. It only valids on Catalina.

VMM flag should be only turned on to update/install .
There are 2 reasons to keep it off : performance loss and no working power management .

According to Martin Lo's video (

) my VMM flag is actually OFF. It seems I have the same symptoms as discussed in this unsolved thread: https://forums.macrumors.com/thread...sur-upgrade-still-appears-how-to-fix.2283091/
