[Guide] Intel Framebuffer patching using WhateverGreen

[SteveEvans]

I'm keen to switch to using Lilu/WEG, as I'm having issues (see HERE) installing Mojave which I believe it may solve. To do this however I need to understand the following.

My current setup using a Gigabyte Radeon RX 560 Gaming OC 4G requires frame buffer patching, first to select the Acre frame buffer and then a patch to correct the connectors.

The selection of the Acre frame buffer is done thus:

        <key>Graphics</key>
        <dict>
                <key>FBName</key>
                <string>Acre</string>
                <key>Inject</key>
                <dict>
                        <key>ATI</key>
                        <true/>
                </dict>
                <key>RadeonDeInit</key>
                <string>true</string>
        </dict>

The frame buffer is then patched thus. This relies on the Acre frame buffer being in place so I know what's being patched against. Without this knowledge I don't know what to find in order to replace it, as I'm not sure where the default frame buffer definition comes from. How would I use this new patching mechanism in such a case?

        <key>KernelAndKextPatches</key>
        <dict>
                <array>
                        <dict>
                                <key>Comment</key>
                                <string>ATI Connector patch new way</string>
                                <key>Disabled</key>
                                <false/>
                                <key>Find</key>
<data>AAQAAAQDAAAAAQEBAAAAABECAgEAAAAAAAgAAAQCAAAAAQIAAAAAACEDBQQAAAAABAAAAAQCAAAAAQMAAAAAAAAAAwUAAAAA</data>
                                <key>InfoPlistPatch</key>
                                <false/>
                                <key>Name</key>
                                <string>AMD9500Controller</string>
                                <key>Replace</key>
<data>AAQAAAQDAAAAAQMAAAAAABECBQEAAAAAAAgAAAQCAAAAAQIAAAAAACEDAwQAAAAABAAAABQCAAAAAQEAAAAAABAABAUAAAAA</data>
                        </dict>
                </array>
        </dict>

Thanks,

Steve

Okay, so I am still new to the whole hackintosh thing. The frame buffer patching will re-enable the IGPU while still leaving the heavy lifting to the discrete GPU, right? Meaning that I can get the benefits of the IGPU, such as Airplay and DRM video on iTunes (broken for some reason, heard this would fix it), while leaving the heavy lifting the the discrete card? Was redirected here from this page on Airplay Mirroring, so that's what I'm guessing. Sorry for asking stupid questions, just sort of lost and don't want to break something. Running 10.13.6 (17G65) btw. I also already have Lilu and WhateverGreen installed.

Hello, I've been trying to fix the HDMI connection on my laptop, and its been frustrating because the connection type keeps resetting when connecting the HDMI, can anyone help me figure this out?
My laptop has 2 externals connections, HDMI and VGA, with the files I uploaded, VGA is working fine and internal display is working. in other hand when I connect the HDMI my internal display turns black and HDMI works. I don't know if brightness is related, but it's working and don't save across restarts.
Every help is appreciated, thank you.

You should post in the appropriate laptop forum.

Hi, I'm a little confused about what value I should set in config.plist Devices/Properties for APPL,ig-platform-id.

Currently running 10.14.1 with RX580 and iGPU - latest Lilu and WEG. If I start FBPatcher I see this:

Should I be taking the value circled and use 300019E3?

Not necessarily. That is just what FB-Patcher detects as your current platform id. To change it you will need platform list data. The easiest way to do that is to use the Framebuffer->macOS 10.14 (18A391) menu option. After that select the appropriate PlatformId for your system and use the Patch tab to generate a patch. Use the File->Export->Clover config.plist to export the patch.

After I generate config.plist on desktop, should I open it with text editor and copy the content and paste into the confit.plist in EFI?

Sorry, still learning~

You should export over your config.plist in your EFI if you want the data to be merged with your current config.plist. It will make a backup (config-backup.plist) before it does this.

I should have mentioned - I'm using RX580 as my GPU - wanting to config the UHD630 'headless' for QuickSync etc. Does that change things? Is there a specific id for that config - I see 10 listed in the PlatformID drop-down after following you're directions?

Thanks
