The advisory also details the steps for failing over to the An圜onnect kernel extension, as last-resort workaround in case a critical system extension (or related OS framework) issue is encountered. There are important changes in approving the An圜onnect system extension, as detailed in the next section.

Warning: I have not attempted these steps (fortunately my Mac is from 2015), so do so at your own risk (and feel free to use any up-to-date guide at that time.) The final version of macOS Monterey released just a couple days ago, so there still may be some undiscovered bugs running it on unofficial hardware, but it appears so far there are no bugs on your model.An圜onnect Changes Related to macOS 11 (And Later)Ģ.

When that ends, if you wish to install macOS Monterey, OpenCore Legacy Patcher supports your MacBook Air and macOS Monterey, so you can follow their instructions.
Nobody knows for sure when macOS Big Sur will stop getting security updates, but as Skye-AT and Tetsujin mentioned, Apple usually provides security updates for OSes up to 3 versions prior, so you probably still have at least 3 years of support. There were some devices that Apple dropped that did have issues with the new update, but the OpenCore Legacy Patcher developers were able to fix them, but your device was never one of the models affected from what I can tell. Performance may not be great, but (in my opinion) that should not block you from installing it (though a warning message would be understandable).
There do not appear to be technical reasons for not allowing you to install macOS Monterey on your MacBook Air (13-inch, Early 2014), as you can install macOS Monterey on your device in an unofficial way.
