I'm not able to run any kind of project in my mac os sequoia

I dowloaded epic games launcher and tried to install unreal engine. I started with version 5.5.4, but during shaders compilation it crashes. So I tried older versions, from 5.4 to 5.2. In this case editor ends succefully the installation, but when I start a new project (even an empty project) it starts computations but then crashes on shaders compilation, so the projects never opens.

Full error here:

This is just a suppossition… i have not a Mac, and i don’t know if it is gon to work…
But, look at this.

-RHIs is used to compile the shaders
-So the problem must be here for sure

By default is checking for MacOs Monterrey or later. → M5

The idea is to check other → M6 for example and see if it does work.

I know you can’t open the editor but this setting are wroten in DefaultEngine.ini file.
You can edit it using a text plane editor like NotePad++ or similar.

you must find somethig this:

[/Script/MacTargetPlatform.MacTargetSettings]
MaxShaderLanguageVersion=2
+TargetedRHIs=SF_METAL_SM5
UseFastIntrinsics=False
EnableMathOptimisations=True

and change this

+TargetedRHIs=SF_METAL_SM5

To this:

+TargetedRHIs=SF_METAL_SM6

The others option i found are this

SF_METAL_SM5_NOTESS
SF_METAL_SM5
SF_METAL_SM6

I hope it works… good luck!!

EDIT:

Other things it can be…

Seems some files can’t be found

1-Maybe your engine installation is incomplete
2-Maybe you need configure some enviroment variable ( a PATH)
