Mac - to sell or not to sell

[GfK]

I have a late 2009 iMac.  Apple won't let me install anything newer than High Sierra 10.13.x. 

Is this thing any use for gamedev?  Can I even build stuff on it that'll run on the latest Macs?  Or shall I just sell it while it's still worth anything on the 2nd hand market?

(Not interested in building mobile apps).

Don't think you'll get much for it now. I've got a mid 2010 iMac that I gave to the missus when I got my current one. That was a pretty good machine back in 2010 but I bought it off a mate in 2015 for around £400. That's 5 years ago. However, while you can't install a lot of newer apps and can't use it for World of Warcraft any more (because it doesn't support metal), it's still a good machine for general use. It's not much less powerful than the machine I have now, in all honesty.

Nothing wrong with using it for testing 2D games or basic 3D ones. Also I'm pretty sure the late 2009 iMacs could run 32 and 64bit apps so it's not useless yet. As Xerra says, it won't support Metal but will OpenGL / DirectX ( bootcamp ).

You can install Mojave and Catalina on an iMac 2009 using this tool - You might fair better with Mojave though.

Actually, that's not a bad idea. My 2010 machine ran parallels pretty well. It was a couple of years ago's versions but it's supposed to run even faster now. Assume you can download an older version if the new one doesn't run.

You mean, install Windows on it via Parallels or Bootcamp?

I've already got two desktop PCs and five laptops, so I probably don't need the Mac pretending to be a PC as well.

It does need to run MacOS, one way or another.  Might give Catalina a go, see what happens.  If it's crap I'll try Mojave.  If that's still no use, eBay.
