How do I determine what OS my computer will support?

How do I determine what operating system version my IMAC will support? (27-inch, Late 2009) I am currently running macOS High Sierra version 10.13.6

I have 5 updates the require OS-X v10.14

Am I running the wrong operating system for this computer?


iMac Line (2012 and Later)

Yes. Your Mac can non longer support run newer macOS versions.


OSx or macOS 10.x is an ever growing series of operating system versions. Each has changes and added features.


So that's like (in the PC world) saying is your computer running system 7 or system 10.

Correct.


10.13 vs 10.14 and 10.15. That's like Windows 7, 8 and 10.


Starting with 10.14 Mojave, the operating system, requires hardware your Mac does not have, and cannot have installed. More specifically a Metal capable video card, which cannot be installed in your Mac.
