Java Duke Posted January 15, 2008 Share Posted January 15, 2008 I'm wondering if it's possible to check the EFI version installed? I know I have EFI because I can boot from GUID partition but I'm not sure which version I'm running. Here's my story: I got more or less stable system finally, NVinject works fine but seems to have some problems with dual monitor and sleep. So I tried gfx strings in boot.plist but got blue screen. Someone recommended upgrading EFI to v8 but maybe I already have one? How can I check it?
