OpenGL issues with 2009 iMac

Hi All,

I’m having some major issues with my 2009 imac when my mac was upgraded to Sierra. This issue maybe part of a bigger issue with my iMac but has anyone else experienced this?

I received a Fatal Error “OpenGL 3.0 or higher is required” The video drivers on this system don’t support OpenGL 3.0.

I was going to see whether I could just download the software but my iMac now fails to boot


Hi @Matthew_Taylor ---- Sorry to hear about the troubles with your iMac. I am not sure how much we can do for you on the startup issues, but I believe that iMac should support OpenGL, as mentioned here.

I assume Apple will be helping you get the machine booting again, but let us know if you’re still seeing OpenGL issues after that and we can definitely take a look.


Thanks Eric,

I’ll let you know how I get on but I fear the iMac is dead & it will need to be replaced. Most likely replacement will be a late 2012 iMac (2.9 Ghz i5 with 8 GB RAM).

Tried this?
