your AMD card is not supported for Sierra, only High Sierra and later

Yes. Now I am back with the Nvidia until i found what's wrong with my EFi
Does someone can take a look at my EFI and say what's wrong? it will be very helpfull
i'm on Sierra 10.12.6
Gigabyte Z390 UD
Gtx 1050 ti 4Go

I can boot but its very random. and i must always load optimized default from Bios and pray

before my computer was working

if your machine boots fine with this EFI, using your nvidia card then that is great, nothing to worry about

if you want to use your new AMD card, upgrade to High Sierra as the earliest macOS to support that card

or as mentioned above, create a new USB opencore installer for Mojave

that's the point , my computer boots not fine and i dont know why.
i want to fix that problem before to upgrade to high sierra (and/or mojave)
