Boot arguments

• -wegdbg to enable debug printing (available in DEBUG binaries).
• -wegoff to disable WhateverGreen.
• -wegbeta to enable WhateverGreen on unsupported os versions (10.15 and below are enabled by default).
• -wegnoegpu to disable external GPU (or add disable-external-gpu property to IGPU).
• -radvesa to disable ATI/AMD video acceleration completely.

• ngfxsubmit=0 boot argument (and disable-gfx-submit property) to disable interface stuttering fix on 10.13
• gfxrst=1 to prefer drawing Apple logo at 2nd boot stage instead of framebuffer copying.
• gfxrst=4 to disable framebuffer init interaction during 2nd boot stage.
• igfxframe=frame to inject a dedicated framebuffer identifier into IGPU (only for TESTING purposes).
• igfxsnb=0 to disable IntelAccelerator name fix for Sandy Bridge CPUs.
• igfxgl=0 boot argument (and disable-metal property) to disable Metal support on Intel.
• igfxpavp=1 boot argument (and igfxpavp property) to force enable PAVP output
• igfxfw=2 boot argument (and igfxfw property) to force loading of Apple GuC firmware
• -igfxnohdmi to disable DP to HDMI conversion patches for digital sound.
• -cdfon (and enable-hdmi20 property) to enable HDMI 2.0 patches.
• -igfxdump to dump IGPU framebuffer kext to /var/log/AppleIntelFramebuffer_X_Y (available in DEBUG binaries).
• -igfxfbdump to dump native and patched framebuffer table to ioreg at IOService:/IOResources/WhateverGreen
• igfxcflbklt=1 boot argument (and enable-cfl-backlight-fix property) to enable CFL backlight patch
• applbkl=0 boot argument (and applbkl property) to disable AppleBacklight.kext patches for IGPU. In case of custom AppleBacklight profile- read here.
• -igfxmlr boot argument (and enable-dpcd-max-link-rate-fix property) to apply the maximum link rate fix.
• -igfxhdmidivs boot argument (and enable-hdmi-dividers-fix property) to fix the infinite loop on establishing Intel HDMI connections with a higher pixel clock rate on SKL, KBL and CFL platforms.
• -igfxlspcon boot argument (and enable-lspcon-support property) to enable the driver support for onboard LSPCON chips. Read the manual
• -igfxi2cdbg boot argument to enable verbose output in I2C-over-AUX transactions (only for debugging purposes).
• igfxagdc=0 boot argument (disable-agdc device property) to disable AGDC.
• igfxfcms=1 boot argument (complete-modeset device property) to force complete modeset on Skylake or Apple firmwares.
• igfxfcmsfbs= boot argument (complete-modeset-framebuffers device property) to specify indices of connectors for which complete modeset must be enforced. Each index is a byte in a 64-bit word; for example, value 0x010203 specifies connectors 1, 2, 3. If a connector is not in the list, the driver's logic is used to determine whether complete modeset is needed. Pass -1 to disable.
• igfxonln=1 boot argument (force-online device property) to force online status on all displays.
• igfxonlnfbs=MASK boot argument (force-online-framebuffers device property) to specify indices of connectors for which online tatus is enforced. Format is similar to igfxfcmsfbs.
• wegtree=1 boot argument (rebuild-device-tree property) to force device renaming on Apple FW.
