Hi guys! I hope this is the right forum since i'm a newbie and this is my first post. So, i've got a Mac Pro 3.1 2x2,8GHzQuad Core and 52 Gb of ram, with an APFS ssd as a start up disc.I installed High Sierra via the Dosdude patcher(thanks dos dude!). At that time my GPU was ATI Radeon 5770 and everything run smoothly. Then, i decided to upgrade to Mojave 10.14.5 so i purchased a flashed evga 680 2gb from e bay.I installed the card before i upgraded and with High Sierra on i had some weird graphic anomalies, like for example glitches in You Tube full screen. Also in System report nothing indicated that my card supports metal.Then i upgraded to Mojave, and when i used the post install tool (without selecting legacy video patch since 680 supports metal) nothing happened! After many efforts i gave it one more try, this time by selecting the legacy video patch and the computer booted normally.But i have no acceleration! I do have the Apple logo and all the booting options, and the funny thing is that i don't get this <<greyish>>frame on menu bar.imovie does not play at all, and photos app is a mess! I need the metal acceleration desperately cause i'm working with Logic X and video.Any help is appreciated!
