Well, this is a list of common boot flags for chameleon based bootloaders, I always forget them, so decided to put it here for “once and for all”… feel free to add more flags in comments if you like 🙂
-x– safe boot
-v– boot inverbose mode, to see actual error or kernel panic error
-f – reload all kext and dump the boot config cache
-s – single user
-F
If you enter some extra boot flags into org.Chameleon.boot.plist, but they’re messing up your Hackintosh’s bootloader, enter the -F boot flag to ignore them.
Mac OS X 10.7 'Lion' ran with a 64-bit kernel on more Macs, and OS X 10.8 'Mountain Lion' and later macOS releases only have a 64-bit kernel. On systems with 64-bit processors, both the 32- and 64-bit macOS kernels can run 32-bit user-mode code, and all versions of macOS include 32-bit versions of libraries that 32-bit applications would use.
-force64
Forces Mac OS X to boot into 64-bit mode.
- Some AMD Radeon cards wont boot without it, PCIRootUID=1 or PCIRootUID=0. Arch=i386 Forces Mac OS X to boot into 32-bit mode. Useful for older PC’s if CPU or graphics card isn’t fully supported in OSX 64 bit mod. No longer works in OS X Mountain Lion which is 64 bit only. Arch=x8664 Allows Mac OS X to boot into 64-bit mode.
- Mac OS X for UNIX Users Mac OS X version 10.4 Tiger combines a robust and open UNIX-based foundation with the richness and usability of the Mac interface, bringing UNIX technology and 64-bit power to the mass market. Apple has made open source and standards a key part of its strategy to deliver an industrial-strength operating system that is both.
- AMD Kernel for OS X Mavericks was Compiled as a joint effort from AnV, Bronya, and Sinetek. This kernel allows full x64 support on all AMD CPUs. Ryzen CPUs Support is not confirmed. This Kernel can be used with following versions of OS X Mavericks.
- AMD Kernel for Mac OS X Snow Leopard. By Hackintosher. By Hackintosher. Nvidia Web Driver Auto Installer. By Hackintosher. By Hackintosher. 4,380 Download Hackintosh Catalina. By Hackintosher. 34,563 Highest Rated.
-legacy
System loads in 32 bit mode while running on 64 bit version of Os X.
rd=diskXsX
Tells where is the boot partition, first X is hdd sata port and second X is partition number ( rd=disk0s1), sometimes can fix “Waiting for boot volume UUID” error.

platform=ACPI
platform=X86PC (non ACPI)
platform=ACPI|86PC (if ACPI fails do not use it)
cpus=1
Limit the number of processor cores (usually used for AMD processors).
PCIRootUID=1
Some AMD Radeon cards wont boot without it, PCIRootUID=1 or PCIRootUID=0
arch=i386
Forces Mac OS X to boot into 32-bit mode. Useful for older PC’s if CPU or graphics card isn’t fully supported in OSX 64 bit mod. No longer works in OS X Mountain Lion which is 64 bit only.
arch=x86_64
Allows Mac OS X to boot into 64-bit mode.
Amd Os X
mach_kernel
Locate the kernel (“mach_kernel”), if your Hackintosh says that it can’t find mach_kernel, and if the kernel is located in the Extra folder, enter the boot flag /Extra/mach_kernel. If you testing new kernel, call it custom and than enter “custom” flag to boot it with custom kernel without of removing old kernel.
darkwake=0
Disable wake up of certain parts of your Mac from sleep, while leaving other parts in sleep mode. This feature often messes up sleep on Hackintoshes. Enter darkwake=1 to turn it on, if turning it off doesn’t do the trick). if your verbose boot is freezing be sure to remove SleepEnabler.kext completely by deleting it from either /Extra/Extensions or /System/Library/Extensions in your hard drive.
GraphicsEnabler=No orGraphicsEnabler=Yes
It’s turned on by default when you set up your Hackintosh with latest Multibeast. Certain graphics cards (AMD Radeon cards), may make Mac OS X unable to boot, or cause the graphics in Mac OS X to display incorrectly. If this is the case use this flag. Turning GraphicsEnabler off will break DVD Player, most games, video and audio editing apps etc… NVIDIA 600 series no longer require GraphicsEnabler to work with OSX so turning off GraphicsEnabler won’t cause any problems.
debug=0x100 or debug=0x144
Wireless utility mac high sierra. Turns on debug mode. If you get a kernel panic use either of these boot flags, and you’ll see a debug screen full of code instead of a kernel panic message.
DSTD=/Extra/DSDT_test.aml
Safe way to test newly patched DSDT file. First rename your new DSDT.aml file to DSDT_test.aml and than copy it to /Extra folder. Or can be used otherway around for DSDT_backup.aml.
Kernel For Mac Os X Amd Ryzen
dart=0
If you can’t boot with OS X and VT-x/VT-d enabled in BIOS, use this flag (UEFI BIOS).
