How to Fix GUI never starts on macOS VMs on ESXi

This mini-guide provides a structural approach to troubleshoot and fix the issue.

Prerequisites

  • Confirm your hardware specifications (CPU, GPU, Motherboard).
  • Ensure you have a bootable recovery USB and backup your EFI.

Fix Steps

  1. Check if your GPU requires WhateverGreen or specific boot-args (e.g., agdpmod=pikera).
  2. Ensure Metal acceleration is fully supported for your macOS version.
  3. Update Lilu and WhateverGreen to the latest versions.

Verification

  • Reboot and verify if the functionality is restored and stable under typical usage.

Original Question:

I'm using the Unlocker 3 from here https://github.com/hugepants/esxi-unlocker

I've never run into this issue before, but it even affects VMs running on nested ESXi hosts so I'm almost tempted to believe it's a problem specific to this hardware. This is on Netapp HCI .

When I go to boot a VM from an ISO, it gets to the point where the GUI would start and I get a beachball cursor and the apple logo is still visible. I've tested this on multiple versions of macOS including Lion, El Capitan, High Sierra, Mojave. same behavior.

I would be inclined to say the the Intel Xeon Silver CPU is not supported, but I can boot into single user mode just fine, and that shouldn't affect the virtual GPU presented to the VMs.

I'm not passing through a GPU or anything. just using the Vmware virtual graphics device. The intent was to create a pool of mac devices for testing rolling out our MDM strategy to non-Windows devices (all the devs that use Macs at work).

Any ideas what might be causing this issue?
