How to Troubleshoot Problems with latest OCLP Mac Pro 6,1 gpu drivers and latest Sonoma 14.5 on macOS

Graphics and media-app issues are normally caused by missing Metal acceleration, an unsupported GPU path, or a fragile patch combination. macOS needs a supported graphics stack; WhateverGreen, NootRX or NootedRed can help only when the underlying GPU path is viable.

Quick Checks

  • Backup current state: Save a copy of your working EFI and run a full system backup before changing settings.
  • Identify hardware components: Note down your exact CPU, GPU, Wi-Fi card, and motherboard/laptop model.
  • Ensure utility alignment: Keep OpenCore, OCLP, and ProperTree updated.

Fix Steps

  1. Create a rollback point: Make a Time Machine backup and keep a copy of your last working EFI folder before editing OpenCore, kexts or root patches.
  2. Verify GPU support first: Confirm the exact GPU model and whether that macOS version supports Metal acceleration for it.
  3. Update graphics kexts: Refresh WhateverGreen, Lilu and any AMD-specific kexts together, not one at a time.
  4. Check boot arguments: Remove old experimental GPU boot args, then add back only the ones required for your hardware.
  5. Test acceleration: Open About This Mac, System Information and a Metal app before testing browsers, GarageBand or Pro Tools.
  6. Reduce app variables: Disable browser hardware acceleration or test another app build if only Chromium, Electron or CEF apps fail.

Do Not Continue If

  • Do not continue if: you do not have a working EFI backup, a Time Machine backup, or another bootable macOS installer.
  • Stop and capture evidence: if the machine stops booting, take a photo of the last verbose line before changing more settings.

Verify It Worked

  • The GPU reports Metal support in System Information.
  • Window animations are smooth and not CPU-bound.
  • The affected app opens after a clean reboot.
  • No repeated GPU restart messages appear in Console.

Rollback

  • Boot with a known-good EFI snapshot.
  • Temporarily remove experimental graphics patches.
  • Return to the last macOS version where acceleration was stable.

Next Action

  • Test now: reboot twice, reproduce the original problem, and confirm whether the same symptom returns.
  • If it still fails: record the Mac model, macOS build, OpenCore or OCLP version, GPU, Wi-Fi/Bluetooth chipset, and the last visible error.
  • Read next: use the related searches below for the nearest OpenCore or OCLP fix before making another change.

Original Question: "Problems with latest OCLP Mac Pro 6,1 gpu drivers and latest Sonoma 14.5?"

Hi all, just updated Sonoma to 14.5 and updated the latest OCLP drivers / patches and things have gone badly. Slot one GPU appears in system profiler and Apple diagnostic reports no issues - but no tasks are ever distributed to slot 1 GPU (when some would trickle in to that card from time to time before. Also Dina cut, arc browser, Apple Music and more lock up and have hanging processes on the slot 2 GPU - using istatistica pro I see both GPU but they seems to report as one and vram fills up almost immediately…. Anyone else see this? Is it possible to roll back your patches?

Thanks!
