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

Prerequisites

  • 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:

Hiya,

I have had this build a year and have had on going issues with USB, I thought it was an hardware issue until I just read that it's common with the Gigabyte Aorus Z390 Boards, however all them threads are achieved so I can't comment to get an update, so here goes.

*Problem* at random times my USB's just stop working, it can happen once a day, once a week, very unpredictable. The only way to get them back is to hard reset the computer.

I use the system for CAD work, granted not professionally however still annoying.

Has anyone fixed this? I have attached my EFI folder.
