edit2: nevermind. seems this guide support Ivy Bridge+ only.

System Definition?

System Definition?

My CPU is Sandy Bridge hence the guide wouldn't work?

Requirements

1. macOS/10.10 or newer
2. Intel 3rd Generation Processor/Core i-3xxx/Ivy Bridge and newer
3. Discrete GPU (macOS recognized and enabled)
   • AMD (7xxx and newer) or
   • Nvidia (6xx and newer)

Do you want help? If yes, answer Post #105.

@toleda Thanks for the great tutorial. Very help.

I do have a question for the instruction. See quote bellow. I assume you wanted to copy the whole section under "Mac-BOARD-ID", and paste under MAC-AMD, and then rename MAC-AMD to Mac-BOARD-ID. Am I right?

If yes, please see attached screenshot for my Info.plist file under dAGPM.kext. Can you confirm is it looks good? Do I need sections like "Vendor..."?

Thanks a lot!

macOS (nearly) Native Discrete GPU Power Management

Add AppleGraphicsPowerManagement.kext support

1. From Table 1/System Definition, copy board-id
2. Download: dAGPM.kext.zip
3. Edit Info.plist
   1. Finder/Show Package Contents: S/L/E/AppleGraphicsPowerManagement.kext/Contents/Info.plist
   2. Use: III. Tools/2. Xcode
   3. Xcode/File/Open/Info.plist
   4. Info.plist/IOKitPersonalities/AGPM/Machines/
   5. Find board-id/IGPU
   6. Copy IGPU
   7. Finder/Show Package Contents: dAGPM.kext/Contents/Info.plist
   8. Xcode/File/Open/Info.plist
   9. AMD:
      • Select "Mac-AMD", paste IGPU on "Mac-AMD"
      • Copy board-id
      • Paste board-id over "Mac-AMD"

Yes.
However, the screenshot shows you used Mac-Nvidia, not Mac-AMD. Try again.

Yes.

Yes it's Nvidia. But from AppleGraphicsPowerManagement.kext, there no AMD vendor. See screenshot bellow, which is from the Info.plist of AppleGraphicsPowerManagement.kext.

How do I add AMD?

True, missed Post #1/II. Installation/3. Add AppleGraphicsPowerManagement.kext support

I did follow the instruction there. Here is the Info.plist file from dAGPM.kext at the end. Does it look good?

My machine's board ID is Mac-FC02E91DDD3FA6A4, model is iMac 13,2.

Thanks.

Table 1: Native AppleGraphicsPowerManagement.kext (AGPM)

Processor Generation	Desktop GFX0 required, unless noted	Laptop GFX0 required	Discrete Graphics (D/L)
8th: Core i-8xxx Coffee Lake	TBA	TBA	AMD

Hi there!

What would be the best choice for a 8700K system (regarding GPU power management) ? Will any of the AMD recommended cards work?

Or do we have to wait till any real Apple computer uses a Coffee Lake processor?

Thanks in advance!

Screenshot is useless, hidden properties.
Ignored instructions; use Mac-Nvidia as is. Do not add GFX0 entries from native kext.
Attach new Info.plist.
