Help for i5 10400. I'm trying to get Catalina installed but it's impossible...

[d1eshi]

Actually I'm trying with Catalina 10.15 I no have video card, so I think it's easily but I no have experience with all the configs.

Someone have an EFI or just can help me

You are using a 500 series motherboard (H510) and the integrated CPU graphics won't work properly in MacOS even with a supported 10th generation CPU like yours.

I recommend either adding a supported graphics card to your build or replace your motherboard with one based on 400 series (H410 / B460 / H470 / Z490) if you want to run MacOS.
