I've got an I MAC brand new with windows 10 and an AMD Radeon R9 M390,
I tried installing the driver with the automatic software but he didn't detect the graphic card
Then i tried installing the driver manually (i selected Imac, then windows 10)
I saw that there's no driver for this device with W10, so i tried the 8.1 driver but it didn't work.
I was at the apple store then for checking if the device is OK, and after some tests they assure me that it has no problem.
Did i select the good products or is this driver still not available ?
