lalegator Posted November 5, 2018 Share Posted November 5, 2018 (edited) i`v just upgraded my graphic card to 580 nitro+ card from gt560ti and i expected to see some improvements, but none came. still 4k is unplayable on mac mojave, on windows it flyes. now i have smbios MacPro5,1 and i while i had imac 14.1 smbios it was smoother. not perfect but watchable. but when i had imac smbios i could open jpeg files on preview and some programs where not working. any solution maybe? played with bios setting, igpu enable/disable...etc, whatevergreen. lillu and other kexts but to no avail.
