I find it funny Apple's phones have longer lifespan than their laptops and desktops.
And that people crapped on Microsoft from cutting off Core2 with Windows 11 (Yes I also think everything 6th gen and newer should have been supported but it is still a longer window than Apple)
My experience of OpenCore is not great. It's very very good but not seamless and some of the security compromises you have to make as too great. I've just stayed on the last 'supported' version of macOS. Some bargains to be had on the second hand market too.
