Installer fails when socket information is missing

[NN708]

When running the installer in an Apple virtualization environment, the installation fails during system checks because the CPU detection can't handle missing socket information.

Error log:

Traceback (most recent call last):

I just merged a fix into main that will allow you to use the IGNORE_RAM and IGNORE_CPU env vars to get past the issue as a workaround
