Probably not seeing the information, how do I check what driver I have and will Apple over write it at some point? Part way through Metro Last Light and been mulling over the redux versions but the poor reviews put me off. Not using Steam, but will be the App store. Down to £7.99 at the moment.
So, are you able to find out what GPU your Mac has? If it's nVidia, you can download their web drivers and use the accompanying control panel to switch back and forth between Apple's drivers and nVidia's drivers. So, you're not committed to the web drivers if you don't want to be. And, if Apple upgrades their OS, and you download it, you'll have to reinstall the web drivers. It happened to me when I upgraded to El Cap.
That said, the web drivers seem to be what has really taken my Metro performance to a new level!
I recommend the Redux versions to anyone with a late 2012 or newer Mac with an nVidia GPU.
