I have an iMac 27" 2020, right now the software is macOS Catalina. I need to update the software to macOS version 12. But when going to do this normally it says my mac is up-to-date. I am a photographer and I need to download adobe lightroom but the macOS version installed isn't new enough. Doing my research my computer should support the version 12 software update but I am just struggling with how to do it. Any advice would be greatly appreciated.

Adobe - Creative Cloud system requirements
Right now, the minimum version of macOS for running PS, LR, and LRC is Big Sur. I suspect that Adobe will change the requirement to Monterey in the fairly near future.
Adobe currently recommends
It is not clear why there is a difference, especially since Adobe bundles PS, LR, and LRC in some Photography Plans.
Adobe – Can I run my Adobe apps on macOS 14 Sonoma?
Adobe claims that there are versions of PS, LR, and LRC that are compatible with Sonoma. It appears that they are still working on many other apps.

What Web browser are you using? If it's not Safari, change your default browser to Safari. Then launch Safari. Use it to access the Apple Support article and the link for the version of macOS you want to install.
Background:
When I was upgrading an older Mac to High Safari, and I was using Firefox as my browser, I got very misleading error messages claiming (falsely) that the item I requested was not available in the U.S. App Store. Temporarily changing my default browser to Safari, and using Safari to access the Support article, got around the problem.
Apparently there is some sort of "magic handshake" that goes on between Safari and the App Store when you click on one of the App Store links for an old version of macOS. Firefox did not know how to do the handshake. The App Store didn't know how to return correct, useful error text. Result: a perfect storm.
Try while in Safe Mode.
Just to add, a 2020 iMac can support the latest version of macOS, Sonoma.

tried that too but no luck. It just says the version is unavailable
Hmmm. Are you certain you have a 2020 iMac and you didn't just buy it in 2020?
I bought it just last week. It says its a Apple 27" iMac 2020. Is there a way you can check for certain that it's that model ?
If that's what it says in "About This Mac" under the Apple menu, that's what it is. It has to be used or refurbished. Where did you buy it?
