Please be sure to select the model you want to upgrade from the dropdown.
Above is a partial list of supported system the drop down only supports 50 entries.
The following older systems 2007-2011 can also be upgraded and will run smoothly, be stable and upgrade to latest point releases on Sonoama. But they are 10-15 years old and on the fringe of what is upgradable and may not be 100% and have various annoying niggles BUT more often then not they upgrade smoothly and get a new lease on life. What is there to loose?
Tip: Sonoma needs minimum 4GB of RAM to run. If you are upgrading an older iMac/Mini/Pro (especially 2007-2011) you will need a wired USB keyboard and mouse to complete the process after which your wireless keyboard should work again. If you have a magic keyboard that plugs in to charge you are good to go. For Mac Pro below you will also need a USB 2.0 hub. You can pick up an Apple Aluminum USB Keyboard for £10-20 and they are nice keyboards to boot.
