How to Fix App Store freezes the entire system on Mac OS Catalina

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:

My setup is ThinkPad T430 (CPU: Intel Core i3 Ivy Bridge, GPU: Intel HD Graphics 4000) with OpenCore. The system boots and works fine, graphics work okay, audio works, but when I try opening App Store, the system freezes and requires a reboot to work again. I've seen people having a similar problem online, but I haven't found a working solution yet.

Does anyone else have this problem? What could be causing it? How do I solve it?
