Hi, I have an issue with macOS Mojave.
I created a bootable SD (because I haven't a physical USB) with Clover EFI Bootloader.
Then I tried to assign the flag "-v" but nothing yet.
How can I boot up macOS? (I have updated the video card, now is a Nvidia RTX 2080 and I have an Intel i9 9990k)

Nvidia RTX 2080 is not supported. 750 Ti also not supported in Mojave.

Remove card and use the HD4600 instead.

I tried with the 750Ti, and it is supported.

Not by macOS Mojave it isn't. It only works because of the nv_disable=1 flag in Unibeast. Look at the amount of Vram in About this Mac. It's probably under 10 MB.

And if I'll try to install the Nvidia's Webdrivers, Will it work then?

Not Buying Advice.

Move to Mojave Desktop Support.
