Enabling Discrete GPU on 2011 Mac Mini and MacBook Pro with Sonoma and OpenCore

Guide:

Understanding the Challenge:**
- You've Success fully installed Sonoma on a 2011 Mac Mini and a MacBook Pro.
- The issue is enabling the discrete AMD HD6750m GPU on the MacBook Pro, as it defaults to the integrated 512MB GPU.

Step-by-Step Solution:**

1. Check OpenCore Configuration:**
   - Ensure you're using the latest version of OpenCore.
   - Review your `config.plist` to ensure it's correctly configured for your MacBook Pro's hardware.

2. Graphics Settings in OpenCore:**
   - In `config.plist`, under `DeviceProperties`, add or modify entries related to your AMD GPU. You might need to specify the correct framebuffer and device ID for the HD6750m.
   - Ensure that the integrated GPU is not disabled in the configuration unless it's necessary for your setup.

3. SSDT and DSDT Patching:**
   - For advanced GPU issues, ACPI patching through SSDT or DSDT might be necessary. This can be complex and requires a good understanding of your machine's ACPI tables.
   - Investigate if there are any existing patches for the 2011 MacBook Pro that address GPU switching issues.

4. macOS System Preferences:**
   - In System Preferences, check the Energy Saver settings. Sometimes, the option to switch graphics cards is available here.
   - If available, toggle the settings to prefer the discrete GPU.

5. Checking for Firmware Limitations:**
   - Some 2011 MacBook Pro models have firmware limitations that might prevent

As the title says, I managed to get Sonoma installed using OpenCore, but the MacBook has a 1GB AMD HD6750m I’d rather use than the 512mb default setting (the macmini only has 512mb and I use it as a Plex server, so I dont care about its limitations). On both I used the latest OpenCore and patched 1.3.0 and it still won’t switch to it when I change the setting in battery options. So, what else could it be? Any help would be great! Thanks!
