- Starting in OS X 10.8 Mountain Lion, OS X automatically restarts when you have a kernel panic, and then displays a similar-looking message for 60 seconds (or until you press a key) telling you.
- AMD Kernel for Mac OS X Snow Leopard (0 reviews) Sign in to follow this. By Hackintosher. Find their other files; 1 Screenshot. AMD Kernel for Snow Leopard was Compiled by Bronya this kernel allows full x64 support on all AMD CPUs including Ryzen CPUs.
The heart of the Mac OS X is the XNU kernel. The kernel refers to the part of an operating system that loads first. It controls and monitors hardware resources like memory, CPU processor allocation and disk drives.The XNU kernel includes code from an old computer architecture system called Mach. Mach is a product of Carnegie Mellon University and has been around since the 1980s.
The heart of the Mac OS X is the XNU kernel. The kernel refers to the part of an operating system that loads first. It controls and monitors hardware resources like memory, CPU processor allocation and disk drives. The XNU kernel includes code from an old computer architecture system called Mach. Mach is a product of Carnegie Mellon University and has been around since the 1980s. This code is responsible for some basic functions within the Mac computer, including virtual memory management and multitasking. The code also gives the Mac OS the authority to reduce the CPU's processing speed should it begin to overheat.
Another part of the kernel is the Input-Output (I/O) Kit. It relies on a specialized, limited version of the C++ programming language to control device drivers. Device drivers are what allow external devices to interact with your computer. For example, your printer may require a device driver on your computer so that you can print from your machine. Handling all the requests and information moving from your computer to other devices -- and vice versa -- is a demanding job. The I/O Kit enables a Mac computer to handle several devices over different technologies at the same time. That's why you can connect devices to a Mac using USB, FireWire and Thunderbolt cables simultaneously.

The third part of the XNU kernel is your computer's security guard and bouncer. Based on the Berkeley Software Distribution (BSD) derivative for UNIX, this part of the kernel is in charge of maintaining system securities and permissions. When you log in to a Mac computer the BSD determines your level of access. An administrator would have nearly free reign and could download or delete programs and other data. Other user levels might not have such liberal permissions. This lets the administrator define which processes a normal user can and can't access. The BSD element of the XNU kernel also helps synchronize processes in the Mac computer.
Also part of Mac OS X are the core services layer and the application services layer. Together with the kernel and hardware, these layers form what computer engineers call a stack. A stack is just a way to conceptualize the relationship of the various layer of a computer's software and hardware. At the bottom of the stack you'll find the hardware and firmware. The next level up is the OS kernel. After that you'll find the core services and then the application services layer. The applications themselves are at the top of the stack.
The core services component of Mac OS X consists of multiple frameworks that allow the computer to process tasks like text searches in various languages and system APIs. The applications services layer is the basic graphic user interface (GUI) system. This is the layer the typical user will see -- it's what creates the graphics environment. The application services layer also acts as a communications channel between various applications, allowing them to interact.
Next, let's look at some Mac OS X features.

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.
-force64
Forces Mac OS X to boot into 64-bit mode.
-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)
Examples: “SL-M2020W/XAA”. 
Include keywords along with product name. Examples: 'LaserJet Pro P1102 paper jam', 'EliteBook 840 G3 bios update'Need help finding your product name or product number?
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.
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.
Amd Mac Os X
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
Slots machine games for free online. 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.
Amd Os X
debug=0x100 or debug=0x144
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.
Kernel For Amd Mac Os X 10.10
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 Amd Mac Os X 10.13
dart=0
If you can’t boot with OS X and VT-x/VT-d enabled in BIOS, use this flag (UEFI BIOS).
