===Hardware and software support===
The last bootable full release of Darwin supported 32-bit and 64-bit Apple PowerPC systems and 32-bit Intel PCs.<ref>{{cite web |url=https://opensource.apple.com/static/iso/release-notes-8.0.1.txt |title=Darwin 8.0.1 Release Notes |date=April 29, 2005 |access-date=August 16, 2023 |archive-date=October 28, 2023 |archive-url=https://web.archive.org/web/20231028121525/https://opensource.apple.com/static/iso/release-notes-8.0.1.txt |url-status=live }}</ref>

Darwin currently includes support for the [[64-bit]] [[x86-64]] variant of the [[X86|Intel x86]] [[microprocessor|processors]] used in Intel-based [[Mac (computer)|Mac]]s and the 64-bit [[ARM architecture|ARM]] processors used in the [[iPhone 5S]] and later, the [[iPod Touch (6th generation)|6th generation iPod Touch]], the [[iPad (2017)|5th generation iPad]] and later, the [[iPad Air]] family, the [[iPad Mini 2]] and later, the [[iPad Pro]] family, the fourth generation and later [[Apple TV]]s, the [[HomePod]] family, and [[Mac (computer)|Mac]]s with [[Apple silicon]] such as the 2020 [[Apple M1]] Macs, as well as the Raspberry Pi 3B.<ref>{{cite web|url=https://github.com/apple/darwin-xnu/blob/2ff845c2e033bd0ff64b5b6aa6063a1f8f65aa32/pexpert/pexpert/arm64/board_config.h#L223|title=XNU board config for BCM2837|website=[[GitHub]]|date=December 16, 2021|access-date=December 5, 2021|archive-date=December 5, 2021|archive-url=https://web.archive.org/web/20211205110901/https://github.com/apple/darwin-xnu/blob/2ff845c2e033bd0ff64b5b6aa6063a1f8f65aa32/pexpert/pexpert/arm64/board_config.h#L223|url-status=live}}</ref><ref>{{cite web|url=https://www.raspberrypi.com/products/raspberry-pi-3-model-b|title=Raspberry Pi 3 Model B|quote="Quad Core 1.2GHz Broadcom BCM2837"|access-date=December 5, 2021|archive-date=December 5, 2021|archive-url=https://web.archive.org/web/20211205212422/https://www.raspberrypi.com/products/raspberry-pi-3-model-b/|url-status=live}}</ref> An open-source port of the [[XNU]] kernel exists that supports Darwin on Intel and [[AMD]] x86 platforms not officially supported by Apple, though it does not appear to have been updated since 2009.<ref>{{cite web |url=https://code.google.com/p/voodoo-kernel/source/checkout |title=Voodoo XNU Kernel Source |access-date=April 25, 2014 |archive-date=September 30, 2015 |archive-url=https://web.archive.org/web/20150930225819/https://code.google.com/p/voodoo-kernel/source/checkout |url-status=live }} Requires an Apache SVN client.</ref> An open-source port of the [[XNU]] kernel also exists for ARM platforms, though it has not been updated since 2016.<ref>{{cite web|url=https://github.com/winocm/xnu|title=XNU on ARMv7|website=[[GitHub]]|date=January 25, 2022}}</ref> Older versions supported some or all of 32-bit [[PowerPC]], 64-bit PowerPC, 32-bit x86, and 32-bit ARM.

It supports the [[POSIX]] API by way of its [[Berkeley Software Distribution|BSD]] lineage (largely [[FreeBSD]] [[User space|userland]]), so a large number of programs written for various other [[UNIX-like]] systems can be [[compiler|compiled]] on Darwin with no changes to the [[source code]].

Darwin does not include many of the defining elements of macOS, such as the [[Carbon (API)|Carbon]] and [[Cocoa (API)|Cocoa]] APIs or the [[Quartz Compositor]] and [[Aqua (user interface)|Aqua user interface]], and thus cannot run Mac applications. It does, however, support a number of lesser-known features of macOS, such as mDNSResponder, which is the [[multicast]] [[domain name system|DNS]] responder and a core component of the [[Bonjour (software)|Bonjour]] networking technology, and [[launchd]], an advanced [[operating system service management|service management]] [[software framework|framework]].
