Is the macos kernel the same as the ios kernel?


Asked by Leo Dickson on Dec 06, 2021 iOS Development Manual



Apple has always published the source code for the macOS kernel, and since macOS and iOS share the same Unix-based XNU core called Darwin (where XNU is an abbreviation for "X is Not Unix"), technically this was also the iOS kernel.
And,
Apple open-sourced the kernel of iOS and macOS for ARM processors. Apple has always shared the kernel of macOS after each major release. This kernel also runs on iOS devices as both macOS and iOS are built on the same foundation. This year, Apple also shared the most recent version of the kernel on GitHub.
Furthermore, Linux kernel resources While the macOS kernel combines the capabilities of a microkernel with Mach and a monolithic kernel like BSD, Linux is just a monolithic kernel. A monolithic kernel is responsible for managing CPU, memory, inter-process communication, device drivers, file system, and system service calls.
Also Know,
Apple later called this operating system iPhone OS, and then iOS. It’s not an exact copy as there are no floating windows on iOS. But iOS and macOS use the same Unix-based core named Darwin as well as many frameworks. The Apple Watch and the Apple TV also run variants of iOS that also rely on Darwin.
In addition,
The Mac OS X kernel has a 32-bit virtual address space whether it runs on a 32-bit or 64-bit machine. Beginning with Mac OS X 10.4, it is possible to create 64-bit user programs, although very few user-space APIs are available in 64-bit versions.
