Dota2 won't launch on mac

[76561198073720070]

i keep getting this error-message when i try launch dota2

Could not find required OpenGL entry point 'glDrawRangeElementsBaseVertex'! Either your video card is unsupported, or your OpenGL driver needs to be updated.

does anyone know anything concrete on how to fix this?
would really appreciate it.

im running mac OS X 10.6.8

upgrade to 10.8

Jim Bond, can you confirm that it runs on 10.8?
and does that mean upgrade the entire operating system or just "patch" it?

euromikeym, I dont know, nor how to find out, im not exactly a wizard with my comp(mac).

Thanks for the replies peeps :)

From everything I've read on it, it won't run on any Mac OS below 10.7 (which sucks, because I'm on 10.6.8 myself and had the exact same problem).

well, minimum requirements state 10.7, it was running fine for me a couple of days ago and i'm running 10.8.4 on an iMac7,1. I would say it's definitely the fact your on 10.6.8 that it doesn't run.

In regard to if this means patching vs an OS upgrade, it's an os upgrade. but os upgrades on the mac side are far less painful than with windows, especially going from 10.6 to 10.8. it would be wise to backup via time machine before proceeding however. Also if you have any old apps not updated for intel processors, they won't work in 10.7+, the most common ones are office 2004 and old blizzard games.

can you post your mac's model identifier? http://www.everymac.com/mac-identification/where-to-find-apple-model-identifiers-model-id-machine-model-for-identification.html

its a iMac 10,1, based on what I know now I'll just DL Mountain Lion, see if that does it:)

Thanks a bunch for the help Bond!

Good Idea! You may also see performance improvements in other games, as 10.8's graphics drivers are much improved over 10.6.8. Do note that 10.9 Maverick's release is suppose to be this fall if you wanted to hold out for that. It will most likely retail for $20 (same as ML) so it's not too much of a loss if you upgrade now.

upgrade system is really worth trying.
