hi you all, i've got a gtx 980 ti recently, but when i boot it on my mac pro, it shows this dos screen before the boot menu appears, photo in attachment, someone can tell me is it normal please? thank you guys.
i've bought a second hand, so though may have some issue, but seems it's normal under hs, when i drow out hs and use other sys, the code line has disappeared.
Actually that screen is sort of helpful when doing FW updates. Apple has abandoned the FW update progress bar with update 138.0.0.0.0. That screen of rolling text shows the progress of the update.
