Good day!!!I'm at work bought an IMac Retina 5k. 27" 2017 V. it comes with Radeon Pro 580 c 8192 Gb of memory.For the service required of him by passing his OS Sierra with the help of a program Prallels Desktop was running Windows 7 x64 Professional.All drivers under this OS have exactly except the video card driver. On off. the website drivers are missing, I would like to know will there be support for Radeon Pro 580 Windows 7 x64 Professional?
