Framebuffer patching in Mojave Binary patching framebuffers using KextsToPatch in Clover is no longer a viable method in Mojave for Skylake and above. Now you need to use Lilu + WhateverGreen. Not just for Mojave This method of framebuffer patching is not only required for Mojave we recommend it for all previous and future releases of macOS. Coffee Lake Users Please note that the new WhateverGreen will not work with fake Kaby Lake platform-id's. You will need to have either macOS 10.14 Beta 4 (18A336e) or macOS High Sierra 10.13.6 (17G2112). The latter is a special build only available to MacBookPro15,1 or MacBookPro15,2 board id's. You can create a macOS High Sierra 10.13.6 (17G2112) installer by running installinstallmacos.py. (Update: vit9696 added back ability to fake Kaby Lake platform-id's) Lilu + WhateverGreen WhateverGreen is going to replace all the other video patching plugins for Lilu (it currently has merged WhateverGreen, IntelGraphicsFixup, NvidiaGraphicsFixup, Shiki and CoreDisplayFixup). Others will likely follow (such as AppleALC, HibernationFixup and IntelGraphicsDVMTFixup). This is aiming to be the all-in-one solution for video. Preliminary 1. Remove: - FakePCIID_Intel_HD_Graphics - IntelGraphicsFixup - NvidiaGraphicsFixup - CoreDisplayFixup - Shiki 2. Turn off all graphics injections in Clover: - config.plist/Graphics/Inject/ATI=NO - config.plist/Graphics/Inject/Intel=NO - config.plist/Graphics/Inject/NVidia=NO - config.plist/Graphics/ig-platform-id= - config.plist/Devices/FakeID/IntelGFX= 3. Disable DSDT Clover fixes: - AddHDMI - FixDisplay - FixIntelGfx - AddIMEI 4. Disable UseIntelHDMI 5. Remove boot argument: -disablegfxfirmware 6. Remove any IGPU and HDMI entries from: - config.plist/Devices/Arbitrary - config.plist/Devices/Properties - config.plist/Devices/AddProperties 7. Remove any IGPU and HDMI related SSDT and DSDT from: - CLOVER/ACPI/patched 8. Renaming GFX0 -> IGPU - WhateverGreen will do this automatically (see caveat below) - Be aware that WhateverGreen does not rename all instances of GFX0 -> IGPU but should be okay in most cases - You may need to include Clover GFX0 -> IGPU rename for other kexts or ACPI patching that require it Compile Lilu + WhateverGreen Download WhateverGreen. Make sure you place the debug version of Lilu into the root of WhateverGreen before you compile. Install Lilu and WhateverGreen kext's into the usual place. Compile WhateverGreen as debug if you want to view debug output. Having trouble compiling? If you're having trouble compiling you can download the official release binaries or download my (unsupported) build_lilu.sh shell script and run it in a folder to download and build Lilu + WhateverGreen using Xcode automatically. I recommend you try the debug versions first (place them into Clover's EFI/Clover/kexts/Other folder). Get the device path of your IGPU: Download and use the gfxutil tool like so: $ ./gfxutil IGPU = PciRoot(0x0)/Pci(0x2,0x0) ig-platform-id For the AAPL,ig-platform-id (AAPL,snb-platform-id for Sandy Bridge) entry Clover requires this value to be in Data format so you need to reverse the bytes. So if you want your platform-id to be 0x3EA50009 first reverse the bytes (0900A53E) then use Xcode's plist editor to add the values to Clover's config.plist. What ig-platform-id should I use for my system? You should choose one that is the closest match to your system. I recommend you do some research on this before choosing one. See post #2 for available options. More info can be found here. You can determine the generation of your CPU by the first digit after the hyphen. Examples: - Intel(R) Core(TM) i5-2760QM (Gen 2) - Intel(R) Core(TM) i7-5257U CPU @ 2.70GHz (Gen 5) - Intel(R) Core(TM) m3-6Y30 (Gen 6) - Intel(R) Core(TM) i5-8350U (Gen 8) Spoofing Intel CPU Gen If you need to spoof a different Intel CPU generation you can use the lilucpu=N boot flag. The N refers to the following Intel generations: 4 SandyBridge 5 IvyBridge 6 Haswell 7 Broadwell 8 Skylake 9 KabyLake 10 CoffeeLake To spoof a CPU you will need to set a valid device-id in your GPU entry in Devices/Properties for the appropriate Intel generation. Eg. Spoofing Skylake (lilucpu=8 boot flag with device-id=0x16190000), Kaby Lake (lilucpu=9 boot flag with device-id=0x12590000).

At the minimum though you should choose an ig-platform-id suitable for your system and place it in config.plist/Devices/Properties like this: Here are some reasons why you might need extra Framebuffer Patching: - Setting DVMT for those who can't set it above 32 MB in BIOS (framebuffer-stolenmem / framebuffer-fbmem) - Setting higher VRAM for 4K users who experience graphical glitches (framebuffer-unifiedmem) - Disabling eGPU (disable-external-gpu) - Enable pixel clock patch for 4K support (enable-hdmi20) - Disabling connectors to enable sleep (framebuffer-pipecount / framebuffer-portcount / framebuffer-conX-type=-1) - Removing CNConnectorAlwaysConnected flag for eDP laptop screens on < 10.13.6 (framebuffer-con0-flags=0x00000090) - Changing connector types to match your systems ports (framebuffer-conX-type) Framebuffer Patching Types We have three different types of patches: 1. Arbitrary (Recommended) framebuffer-patch-enable (required to enable below) framebuffer-framebufferid (optional; defaults to current platform-id) (all below are optional) framebuffer-mobile framebuffer-pipecount framebuffer-portcount framebuffer-memorycount framebuffer-stolenmem framebuffer-fbmem framebuffer-unifiedmem framebuffer-cursormem (Haswell only) framebuffer-camellia framebuffer-flags framebuffer-conX-enable (required to enable below) framebuffer-conX-index framebuffer-conX-busid framebuffer-conX-pipe framebuffer-conX-type framebuffer-conX-flags 2. All Data framebuffer-conX-enable (required to enable below) framebuffer-conX-alldata 3. Find / Replace framebuffer-patchX-enable (required to enable below) framebuffer-patchX-framebufferid (optional; defaults to current platform-id) framebuffer-patchX-find framebuffer-patchX-replace framebuffer-patchX-count (optional; defaults to 1) You should place your patches in config.plist/Devices/Properties in Clover config.plist. Here are some example patches: - 32MB BIOS, 19MB stolen (framebuffer) 9MB fbmem (cursor) 2048MB unifiedmem (vram) - Pipe / Port Count 3 to 2 - Connector 1 DP to HDMI - Connector 2 Disable Here is an example of the All Data method: Here is an example of the Find / Replace method: Framebuffer Dumps There are two ways to dump your framebuffer data (both require WhateverGreen + Lilu debug versions): 1. Using -igfxdump boot flag to dump IGPU framebuffer kext to /AppleIntelFramebuffer_X_Y (root of your boot drive) There are several ways of reading this dump: - Using 010 Editor along with the IntelFramebuffer.bt template - Using Hackintool File->Open menu 2. Using -igfxfbdump boot flag to dump native and patched framebuffer table to ioreg at IOService:/IOResources/WhateverGreen There are several ways of reading this dump: - Using dump_platformlist.sh shell script - Using Hackintool File->Import->IOReg Dump menu 3. Using Hackintool Framebuffer->macOS 10.14 menu Adjusting the brightness on a laptop 1. Method 1 Enable Clover DSDT fix AddPNLF. Enable SetIntelBacklight and SetIntelMaxBacklight. A specific value is not necessary - it will be automatically injected according to the processor installed. 2. Method 2 Use this ACPI table: SSDT-PNLF.dsl SSDT-PNLF.aml Do not use both methods at the same time! Digital Audio (HDMI / DVI / DP) To enable digital audio it is necessary to set the necessary properties and, usually, patch the connectors. To enable audio in general and HDMI in particular use WEG along with AppleALC.kext. On 10.10.5 and above, WEG automatically changes the connector-type of DP (00040000) to HDMI (00080000) if no custom patches are used. The actual connection may be of any type (HDMI / DVI / DP), but for the digital audio to function the connector-type must explicitly be HDMI. VGA support In most cases with Intel Skylake and newer it works by default. For Ivy Bridge and possibly other generations there are the options to patch your connectors with the following: 06020000 02000000 30000000 // Option 1 06020000 01000000 30000000 // Option 2 On OS X 10.8.2 and newer it is impossible to have VGA on Ivy Bridge systems. Hot-plugging VGA usually does not work. In case this doesn't help - there are no other known solutions at this time. EDID EDID is usually correctly identified, so no actions are required. In rare cases, EDID needs to be injected manually. An EDID dump can be obtained, for example, with Linux. The correct EDID must be put into *AAPL00,override-no-connect* property for IGPU, where the second 0 stands for the display number. In some cases the EDID dump may be incompatible with macOS and leads to distortions. For some EDID in such cases you can use this script, which corrects a provided EDID and saves it to your desktop. HDMI in UHD resolution with 60 fps Add the enable-hdmi20 property to IGPU, otherwise you will get a black screen. Or instead of this property use the boot-arg -cdfon Disablng a discrete graphics card Add the disable-external-gpu property to IGPU. Or instead of this property, use the boot-arg -wegnoegpu Fix the invalid maximum link rate issue on some laptops (Dell XPS 15 9570, etc.) Add the enable-dpcd-max-link-rate-fix property to IGPU, otherwise a kernel panic would happen due to a division-by-zero. Or instead of this property, use the boot-arg -igfxmlr. You could also manually specify a maximum link rate value via the dpcd-max-link-rate for the builtin display. Typically use 0x14 for 4K display and 0x0A for 1080p display. All possible values are 0x06 (RBR), 0x0A (HBR), 0x14 (HBR2) and 0x1E (HBR3). If an invalid value is specified, the default value 0x14 will be used instead. If this property is not specified, same as above. Fix the infinite loop on establishing Intel HDMI connections with a higher pixel clock rate on Skylake, Kaby Lake and Coffee Lake platforms Add the enable-hdmi-dividers-fix property to IGPU or use the -igfxhdmidivs boot argument instead to fix the infinite loop when the graphics driver tries to establish a HDMI connection with a higher pixel clock rate, for example connecting to a 2K/4K display with HDMI 1.4, otherwise the system just hangs (and your builtin laptop display remains black) when you plug in the HDMI cable. 1. General Notes For those who want to have "limited" 2K/4K experience (i.e. 2K@59Hz or 4K@30Hz) with their HDMI 1.4 port, you might find this fix helpful. For those who have a laptop or PC with HDMI 2.0 routed to IGPU and have HDMI output issues, please note that this fix is now succeeded by the LSPCON driver solution, and it is still recommended to enable the LSPCON driver support to have full HDMI 2.0 experience. (You might still need this fix temporarily to figure out the connector index of your HDMI port. See the LSPCON section below.) LSPCON driver support to enable DisplayPort to HDMI 2.0 output on IGPU 1. Brief Introduction Recent laptops (Kaby Lake/Coffee Lake-based) are typically equipped with a HDMI 2.0 port. This port could be either routed to IGPU or DGPU, and you can have a confirmation on Windows 10. Intel (U)HD Graphics, however, does not provide native HDMI 2.0 output, so in order to solve this issue OEMs add an additional hardware named LSPCON on the motherboard to convert DisplayPort into HDMI 2.0. LSPCON works in either Level Shifter (LS) or Protocol Converter (PCON) mode. When the adapter works in LS mode, it is capable of producing HDMI 1.4 signals from DisplayPort, while in PCON mode, it could provide HDMI 2.0 output. Some onboard LSPCON adapters (e.g. the one on Dell XPS 15 9570) have been configured in the firmware to work in LS mode by default, resulting a black screen on handling HDMI 2.0 connections. Starting from version 1.3.0, WhateverGreen now provides driver support for the onboard LSPCON by automatically configuring the adapter to run in PCON mode on new HDMI connections, and hence solves the black screen issue on some platforms. 2. Before you start LSPCON driver is only applicable for laptops and PCs with HDMI 2.0 routed to IGPU. LSPCON driver is necessary for all newer platforms unless the new IGPU starts to provide native HDMI 2.0 output. Supported Intel Platform: Skylake, Kaby Lake, Coffee Lake and later. Skylake Case: Intel NUC Skull Canyon; Iris Pro 580 + HDMI 2.0 with Parade PS175 LSPCON. Coffee Lake Case: Some laptops, e.g. Dell XPS 15 9570, are equipped with HDMI 2.0 and Parade PS175 LSPCON. If you have confirmed that your HDMI 2.0 is routed to IGPU and is working properly right now, you don't need to enable this driver, because your onboard LSPCON might already be configured in the firmware to work in PCON mode. 3. Instructions Dump your kernel log and you should also be able to see something simillar to lines below. // When you insert the HDMI 2.0 cable igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB0] called with controller at 0xffffff81a8680000 and framebuffer at 0xffffff81a868c000. igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB0] No LSPCON chip associated with this framebuffer. igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB0] Will call the original method. igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB0] Returns 0x0. igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB2] called with controller at 0xffffff81a8680000 and framebuffer at 0xffffff81a869a000. igfx @ (DBG) SC: LSPCON::probe() DInfo: [FB2] Found the LSPCON adapter: Parade PS1750. igfx @ (DBG) SC: LSPCON::probe() DInfo: [FB2] The current adapter mode is Level Shifter (DP++ to HDMI 1.4). igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB2] LSPCON driver has detected the onboard chip successfully. igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB2] LSPCON driver has been initialized successfully. igfx @ (DBG) SC: LSPCON::getMode() DInfo: [FB2] The current mode value is 0x00. igfx @ (DBG) SC: LSPCON::getMode() DInfo: [FB2] The current mode value is 0x00. igfx @ (DBG) SC: LSPCON::getMode() DInfo: [FB2] The current mode value is 0x00. igfx @ (DBG) SC: LSPCON::getMode() DInfo: [FB2] The current mode value is 0x01. igfx @ (DBG) SC: LSPCON::setMode() DInfo: [FB2] The new mode is now effective. igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB2] The adapter is running in preferred mode [Protocol Converter (DP++ to HDMI 2.0)]. igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB2] Will call the original method. igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB2] Returns 0x0. // When you remove the HDMI 2.0 cable igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB0] called with controller at 0xffffff81a8680000 and framebuffer at 0xffffff81a868c000. igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB0] No LSPCON chip associated with this framebuffer. igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB0] Will call the original method. igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB0] Returns 0x0. igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB2] called with controller at 0xffffff81a8680000 and framebuffer at 0xffffff81a869a000. igfx @ (DBG) SC: GetDPCDInfo() DInfo: [FB2] LSPCON driver (at 0xffffff802ba3afe0) has already been initialized for this framebuffer. igfx @ (DBG) SC: LSPCON::setModeIfNecessary() DInfo: [FB2] The adapter is already running in Protocol Converter (DP++ to HDMI 2.0) mode.

poles89 posted a topic in OSx86 10.14 (Mojave)Hi guys, Though native graphics acceleration is supported on i3 from Mojave, I'm not able to manage to get it. This is my system configuration : Motherboard: Asus Prime H370-Plus CPU: i3-8100 (UHD 630) OS: Mojave 10.14.2 I'm trying every possible way to get full graphics acceleration. But whatever I try it shows only 4MB video memory or leads to Kernal Panic. Here are some ways I have tried so far: Prerequisites: Installed latest Lilu+WEG on L/E. set DMVT prealloc to 64MB on bios. Option 1: IntelGFX-> 0x3E928086, ig-platform-id-> 0x3E9B0007, Inject Intel = true. Output: Kernal Panic Option 2: Blank IntelGFX, blank ig-platform-id, Inject Intel = false Output: Kernal Panic Option 3: IntelGFX-> 0x3E928086, ig-platform-id-> 0x5912000, Inject Intel = true. Output: Booted Successfully but no graphics acceleration. I knew that ig-platform-id-> 0x5912000 doesn't work in mojave and its works only for high sierra but I set this because with this ig-platform-id I can boot. Another way I can boot it by setting invalid Fake IntelGFX value like 0x12345678. Option 4: Downloaded Intel FBPatcher & followed this guide. But as I opened the app, its shows like this: It clearly indicates it neither can detect Intel CPU generation nor GPU memory (currently shows 0 MB). I changed to different PlatformId from the drop down but no improvement. Anyway I applied a patch with SMBIOS ->Macmini8,1 by someione's recommendation . I attached a config file (config_fbpather.plist) for this. Output: Kernal Panic I have tried the upper mentioned methods with SMBIOS like iMac14,2 / iMac18[1,2,3] and Macmini8,1. I'm using HDMI port for display output. Now I don't know whats wrong with theses methods but maybe someone can help me to figure out this problem. I have also attached those config.plist files. Thanks in advance. config_fakeid_0x3E928086.plist config_fbpatcher.plist config_fbpatcher_with_device_id.plist config_platform-id_0x59120000.plist
macinsane posted a topic in ATiThis is bothering me for a long time now: Why does Apple deliberately disables the the RX4xx, RX5xx capabilities to hardware encode HEVC and is using Intel Quicksync instead? Is it to make the iMacPro look better than it is? I stumbled over a thread at tony-mac where people are going a totally different road for Radeon graphics. Instead of hassling around with getting Quicksync to work, they proposed to activate the AMD hardware renderer for Polaris GPU's. I tried it out and it works...somewhat I used a dummy kext from that tomato thread and edited it, so that it enables the AMDU7V4 IOGVACodec like on Vega cards, switched to iMacPro1,1 SMBIOS from iMac18,3, disabled the IGPU and the results were astonishing: My 3:34min 4k50p film was rendered by FCP with HEVC in 2:34 minutes. Nearly half the time than with Quicksync! With the iMac18 SMBIOS and the "help" of Intel Quicksync it took FCP 4:41 minutes to get it done! The problem is: As soon as the "wrong" IOGVACodec is enabled H.264 encoding leads to Mojave crashing at once (be it FCP, QuickTime or Videoproc). Watching H264 material is fine, though. If anyone has any idea how to handle this, I would be very grateful. I would even accept Mojave using software encoding for H264 if I could keep this amazing speeds on HEVC! BTW: Without IGPU on iMacPro1,1 SMBIOS no problem with DRM or iTunes, no need for Whatevergreen or Shiki. That is a bonus Ellesmere.kext.zip
