The Mobility Radeon HD 5670 Mac Edition was a graphics card by ATI, launched in April 2010. Any suggestions on this issue? Ati Radeon Hd 5670 Driver Mac Os X ![]() I assumed Windows 7 woudl simply detect the ATI and simply work. It does not appear anywhere and I cannot change the driver and still see the PnP monitor on Standard VGA Adaptor and the program still does not run. I assumed I needed to install the HD 5670 driver and accordingly I downloaded the driver for the HD 5670 and with ATI Catalyst Install Manager installed this (seemed to install fine). The monitor shows 'Generic PnP Monitor on Standard VGA Adapter'. Evertime I try ro run a specific program 'Avidyne Release 9 PC Simulator' (an aviation simulation package) I get the error 'Missing WGL ARB extension' followed by 'Missing open GL driver'. I have a current iMac27' and have installed bootcamp and Windows 7 Professional.
