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 history of macOS, Apple's current Mac operating system formerly named Mac OS X until 2011 and then OS X until 2016, began with the company's project to replace its "classic" Mac OS. That system, up to and including its final release Mac OS 9 , was a direct descendant of the operating system Apple had used in its Mac computers since their ...
In addition, the Mac OS X kernel has been rebuilt to run in 64-bit mode on some machines. On those machines, Snow Leopard supports up to 16 terabytes of RAM. Newer Xserve and Mac Pro machines will run a 64-bit kernel by default; newer iMac and MacBook Pro machines can run a 64-bit kernel, but will not do so by default. [44]
Faster kernel builds and with lower peak memory use. Removed support for the Intel ICC compiler. 6.2 19 February 2023 [1] 6.2.16 [10] 17 May 2023 [31] Intel Arc drivers are now deemed "stable" and on by default. Initial FOSS support for NVIDIA GeForce 30 Series. But performance is poor for now. Support for Apple's M1
Xcode 3.1 was an update release of the developer tools for Mac OS X, and was the same version included with the iPhone SDK. It could target non-Mac OS X platforms, including iPhone OS 2.0. It included the GCC 4.2 and LLVM GCC 4.2 compilers. Another new feature since Xcode 3.0 is that Xcode's SCM support now includes Subversion 1.5.

The Linux kernel is a free and open source, [12]: 4 Unix-like kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNU operating system (OS) which was created to be a free replacement for Unix.
This expanded API is what is called Kernel Mode-setting (KMS) and the drivers which implement it are often referred to as KMS drivers. In March 2009, KMS was merged into the Linux kernel version 2.6.29, [30] [143] along with KMS support for the i915 driver. [144] The KMS API has been exposed to user space programs since libdrm 2.4.3. [145]
