Looks like booting from install media is a no-go; immediate crash here on Skylake.

 

EDIT: Apple dropped support for Skylake with Kaby Lake being the minimum. 

Officially supported models for macOS Ventura:

What happens if you use Cpuid1Data and Cpuid1mask form a kabylake or a newer processor for your skylake cpu?

First attempt installing, at the first reboot Apple Logo but no progress bar, stays there and does nothing... 

Ventura is gone be a tough nut to crack, it appears...

Are you running Lilu? In that case you might need to add the boot argument: "-lilubetaall" (without the quotes of course) in order to force Lilu and its plugins to load on a new unsupported macOS version.

Thanks for the tip! I was thinking of testing with supported SMBIOS and Board-ID first. Shall see how that goes.

You're welcome and yeah you also need to use 2017 or newer SMBIOS settings.

2017 iMacs don't have a T2 Chip and they are supported.
