XNU ("X is Not Unix") is the computer operating system (OS) kernel developed at Apple Inc. since December 1996 for use in the Mac OS X (now macOS) operating system and released as free and open-source software as part of the Darwin OS, which, in addition to being the basis for macOS, is also the basis for Apple TV Software, iOS, iPadOS, watchOS, visionOS, and tvOS.
A kernel is a component of a computer operating system. [1] A comparison of system kernels can provide insight into the design and architectural choices made by the developers of particular operating systems.
The most popular PowerPC emulation tools for Mac OS/Mac OS X are Microsoft's Virtual PC, and the open-source QEMU. [8] Linux dual-booting is achieved by partitioning the boot drive, installing the Yaboot bootloader onto the Linux partition, and selecting that Linux partition as the Startup Disk. This results in users being prompted to select ...
To perform useful functions, processes need access to the peripherals connected to the computer, which are controlled by the kernel through device drivers. A device driver is a computer program encapsulating, monitoring and controlling a hardware device (via its Hardware/Software Interface (HSI)) on behalf of the OS. It provides the operating ...

In computing, a loadable kernel module (LKM) is an object file that contains code to extend the running kernel, or so-called base kernel, of an operating system. LKMs are typically used to add support for new hardware (as device drivers ) and/or filesystems , or for adding system calls .
The book covers installation, management, and use of the OS, and serves as a hardcopy manual. Apple later released the Open Firmware-based Power Macintosh computers, an official PowerPC branch of the Linux kernel was created and was spearheaded by the LinuxPPC project. [7]
Computers often have many diverse and customized device drivers running in their operating system (OS) kernel which often contain various bugs and vulnerabilities, making them a target for exploits. [17] Bring Your Own Vulnerable Driver (BYOVD) uses signed, old drivers that contain flaws that allow hackers to insert malicious code into the ...
