Boot arguments explained

Incomplete list of commonly used (and rather uncommon) boot-args and device properties that can be injected by boot managers such as OpenCore and Clover. These are not simply copied and pasted from their respective repositories; I tried to provide additional information about where I could gather it. I also used tables instead of lists to separate boot-args, properties and descriptions more clearly, which makes it easier to copy entries and identify additional parameters associated with a boot-arg/property (such as switches and bitmasks).

Debugging

Boot-arg	Description
`-v`	Verbose Mode. Replaces the progress bar with a text output of the boot process which helps identifying issues. Combine with `debug=0x100` and `keepsyms=1`
`-s`	Single User Mode. This mode will start the terminal mode, which can be used to repair your system. Should be disabled with a Quirk since you can use it to bypass the Admin account password.
`-x`	Safe Mode. Boots macOS with a minimal set of system extensions and features. Very useful if Root Patches applied by OpenCore Legacy Patcher no longer work and macOS won't boot after applying the patches. Just boot into Safe Mode, revert the root patches, delete the boot-arg, reboot (and wait for an updated version of OCLP that fixes the issue).
`-f`	Enables cacheless booting in Clover. OpenCore uses a different option: change `Kernel/Scheme/KernelCache` from `Auto` to `Cacheless`. Only applicable to macOS 10.6 to 10.9!
`debug=0x100`	Disables WatchDog. Prevents the machine from restarting after a kernel panic so you can check the errors on screen (if verbose mode is enabled).
`keepsyms=1`	Companion setting to `debug=0x100` that tells the OS to also print the symbols on a kernel panic. This can give some more helpful insight as to what's causing the panic.
`dart=0`	Disables VT-x/VT-d. Nowadays, `DisableIOMapper` Quirk is used instead.
`cpus=1`	Limits the number of CPU cores to 1. Helpful in cases where macOS won't boot or install otherwise.
`npci=0x2000`/ `npci=0x3000`	Disables PCI debugging related to kIOPCIConfiguratorPFM64. Alternatively, use `npci=0x3000` which also disables debugging of gIOPCITunnelledKey. Required when stuck at `PCI Start Configuration` as there are IRQ conflicts related to PCI Lanes. Not needed if `Above4GDecoding` can be enabled in BIOS
`-no_compat_check`	Disables macOS compatibility checks. Allows booting macOS with unsupported SMBIOS/board-ids. Downsides: For installing macOS, you still need a supported SMBIOS temporarily You can't install system updates if this boot-arg is active. This restriction can be lifted by adding `RestrictEvents.kext` and boot-arg `revpatch=sbvmm` but it requires macOS 11.3 or newer
`-liludbgall`	For debugging Lilu kext and plugins (requires DEBUG build of Lilu and asociated plugins)

Tip

Recommended boot-arg for installing macOS the first time: -v, keepsyms=1 and debug=0x100
A more in-depth debugging guide can be found here

Network-specific boot arguments

Boot-arg Description

dk.e1000=0 (Big Sur)
e1000=0 (Monterey) Prohibits Intel I225-V Ethernet Controller from using com.apple.DriverKit-AppleEthernetE1000.dext (Apple's new Driver Extension) and uses AppleIntelI210Ethernet.kext instead. This is optional since most 400-series mainboards (and newer) with an I225-V NIC are compatible with the .dext version of the driver. It's required on some Gigabyte boards which can only use the .kext driver.
⚠️ These boot-args no longer work in macOS Ventura, since the .kext version was removed from the IONetworkingFamily.kext (located under /S/L/E/)!

Other useful boot arguments

Boot-arg	Description
`alcid=X`	For selecting a layout-id for AppleALC, where `X` needs to be a numerical value specifying the layout-id. See supported codecs to figure out which layout to use for your system's audio CODEC.
`amfi=0x80` or `amfi_get_out_of_my_way=1`	Both args are identical. It's actually a bitmask. Setting it to `0x80` disables Apple Mobile File Integrity (AMFI). AMFI is a macOS kernel module enforcing code-signing and library validation which strengthens security. Requires `SIP` to be disabled as well!
`-force_uni_control`	Force-enables Universal Control service in macOS Monterey 12.3+
