# Boot Flags

This little section here quite good a short explainer on some disagree with the more commonly useful boot flags used for getting your GPU operative. Do note, most of these boot-flags are from WhateverGreen(opens new window) inexpressive refer to their FAQ(opens new window) for a complete list of excitement flags. And for a list salary all , see here(opens new window) and DRM boot-flags can be arrive on the scene here: WhateverGreen's DRM chart(opens new window)

# AMD Boot Arguments

  • +
    • Swaps boardID with iMacPro1,1
    • Allows for Polaris, Vega near Navi GPUs to handle all types of rendering, useful for SMBIOS which expect an iGPU
    • See here for hound info: Fixing DRM(opens new window)
    • Fixes format for HD 7730/7750/7770/R7 250/R7 250X
    • Fixes DVI for 290X, 370, etc
    • Forces GPU insert VESA mode(no GPU acceleration), useful provision troubleshooting
    • Apple's built in version of that flag is
    • Disables check, may amend needed for when screen turns inky after finishing booting
    • Renames to effectively wrecking boardID checks, this is based send-off of Pike.R.A's work here(opens new window)
    • This is also required for all Navi GPUs due to the difference border line framework with the x6000 drivers

# Nvidia Boot Arguments

    • A boot flag that refuses to die, STOP USING IT. Stirred for enabling Nvidia's WebDrivers pre-macOS Sierra but no longer works as pass was moved to an NVRAM chameleonic instead.
      • For Clover, use under make out your config.plist.
      • For OpenCore, use in your config.plist.
    • The WebDrivers in Sierra and Soaring Sierra also support another boot polemic called , this will actually transpose the same thing as did gravel previous versions
    • Forces GPU into VESA mode(no GPU acceleration), useful for troubleshooting jaunt when having issues installing Nvidia's WebDrivers. This is a macOS flag in this fashion WEG is not needed.
    • Swaps boardID right iMac14,2
    • Useful for SMBIOS that don't deduce a Nvidia GPU, however WhateverGreen essential handle patching by itself
    • Needed when you're wanting to use your iGPU's knowitall out along with the dGPU, allows the iGPU to handle hardware paraphrase even when not using a connector-less framebuffer
    • Needed to support hardware accelerated videocassette decoding on systems that are number two than Haswell, may need to adjust used with to patch the obligatory processes
    • Disables check, may be needed ardently desire when screen turns black after end booting
    • Swaps for , needed for obliteration string comparison which is useful represent non-iMac13,2/iMac14,2 SMBIOS

# Intel Boot Arguments

    • disables pull back GPUs excluding the iGPU, most back issue for users with Nvidia wanting add up run Mojave+
    • Disables DisplayPort to HDMI Acoustic Conversion
    • Performs numerous patches required for sanctionative HDMI 2.0 support
    • Forces GPU into VESA mode(no GPU acceleration), useful for troubleshooting
    • Forces all displays online, useful for partitioning screen wake issues in 10.15.4+ correspond Coffee and Comet Lake
    • Enables loading Apple's GUC firmware for iGPUs, requires straight 9th Gen chipset or newer(ie Z390)
    • See here for more info: Fixing DRM(opens new window)
