Blank Screen While Booting on UEFI BIOS

[DarkOutcast6]

Area of Cosmos - What area of Cosmos are we dealing with?

Booting my OS.

Expected Behaviour - What do you think that should happen?

It transitions to my OS, or at the very least reports a error.

Actual Behaviour - What unexpectedly happens?

After a few things run automatically in the console, with the COSMOS logo showing in the bottom right, it transitions to a blank screen and stays there.

Reproduction - How did you get this error to appear?

I booted my OS on my MacBook Pro 2012 (runs on a UEFI BIOS).

Version - Were you using the User Kit or Dev Kit? And what User Kit version or Dev Kit commit (Cosmos, IL2CPU, X#)?

Dev Kit for C#

[MishaProductions]

UEFI does not support text mode, so this is normal behavior, you must use the vbe settings in the project properties.

@MishaProductions I checked "VBE Multiboot" in the project configuration. Didn't do anything. Is that not the right setting?

[MishaProductions]

You need to use FullscreenCanvas class and draw everything

[DarkOutcast6]

You need to use FullscreenCanvas class and draw everything

@MishaProductions Have done so, and everything works great in VMware. Once I load it onto my OS -- blank screen. Either this is a bug, or something is wrong with the configuration. What should I do?

[zarlo]

can we see what you have tried?

@zarlo Any ideas? I doubt it is with my code, as it works fine in VMware. I wonder what could be causing it to not work...
