Chapter in this post:
With every new version of an Apple operating system, the question arises as to which (older) devices can install the corresponding upgrade. And every year there are developers who make it their task to bring the new OS versions to devices that are not intended for them; especially on the Mac. For example, if you want to install the current beta of macOS 11.0 Big Sur on an old Mac, iMac or MacBook, you get the chance with a corresponding patcher. Below you will find the download source, a list of compatible devices and further information. Disclaimer: Try it out at your own risk.
Like me you already shown in a compatibility list the new Mac operating system "Bis Sur" is no longer compatible with all Apple computers that have also received "Catalina". The 11 version will get MacBooks from 2015, iMacs from 2014 and so on. The MacBook Air and Pro from the end of 2013 go back the furthest. However, if you want to install Big Sur on an Apple Mac, iMac, MacBook or Mac mini from 2012, the patcher mentioned above offers a chance. You can download it from an info page with detailed information on installation and use with this link.
I have listed here which models are compatible and which restrictions arise:

In the above-linked article on the compatibility of the new Mac operating system from Apple you will also find a list of the most important new features and innovations. If you want to read more about this, I recommend mine Apple WWDC 2020 summary. In addition, in recent years the blog has been about patchers with which current systems can be installed on computers and laptops from Cupertino that are not actually intended for this purpose. Here are the corresponding contributions: macOS Catalina Patcher for 10.15 on older Macs and Install macOS Mojave on old, unsupported Macs.
