For what it's worth, Sierra bricked my 2011 iMac. Initially the update installation simply failed, so after finally successfully rebooting I deleted the update file thinking it might be corrupt. I then re-downloaded and tried again. This time, my iMac would chime on power up and then promptly shut itself down again. So then I booted from an external drive and wiped my HD to do a clean Sierra installation. Failed again. I'm back on El Capitan now, and I assume I will be there forever or until they stop supporting it. It's a pity, as my 2011 iMac is a lovely and fast machine...
Oct 03, 2018 No, you should not attempt to work around the model limitations for Mojave - they are there for a reason. Some of your hardware components will not work properly with Mojave and the system will be unstable. Not worth it. Am happily using the same.
Oct 08, 2019 From a security standpoint, using the latest version of macOS—the Mac operating system—is always preferred. However, if your Mac is several years old, there’s a good chance that the current version of macOS won’t run on your Mac; Apple drops support for Mac models that it declares to be vintage or obsolete.
In October last year, Apple releases a new version of macOS dubbed as ‘Catalina.’ This latest installment of macOS includes new features, including new apps for podcasts, music, and TV (replacing iTunes), the ability to use iPad as an external monitor, a revamped Photos app, and many more.
