There is an unofficial patch to the Sierra installer that you can try, but of course, it’s very unsupported and you could end up with a system that will not boot. There’s also a very real possibility that your wi-fi will not be supported and you will need to install third-party USB wi-fi dongle to get wireless back.

If this is your primary computer, I wouldn’t recommend it.

Hi, I have a 2008 24-inch iMac 3.06 GHz with 4GB memory. It has a SSD, but won’t install Sierra. The last version of OS X I was able to install was El Capitan. The computer still works fine and I would hate to invest in a new computer just to take advantage of the new operating system. How can I take advantage of the new OS on this old computer?
