MAC OS X OPERATING SYSTEMS HISTORY FOR MAC OS X

After this point the kernel changed from the NeXTSTEP/OPENSTEP/Rhapsody to the newer XNU for Mac OS X.

0.1 is contrived (for sorting and identification) as this identified itself simply as Rhapsody 5.3.

Note that the corresponding releases may have been released on a different date.Дarwin 0вЂ“11 and corresponding Mac OS X releases Version The following is a table of major Darwin releases with their dates of release and their derivative operating system releases.

Previous versions were released under an earlier version of the APSL license, which did not meet the FSF definition of free software, although it did meet the requirements of the Open Source Definition.

MAC OS X OPERATING SYSTEMS HISTORY SOFTWARE LICENSE

In July 2003, Apple released Darwin under version 2.0 of the Apple Public Source License (APSL), which the Free Software Foundation (FSF) classifies as a free software license incompatible with the GNU General Public License.

It does, however, support a number of lesser-known features of macOS, such as mDNSResponder, which is the multicast DNS responder and a core component of the Bonjour networking technology, and launchd, an advanced service management framework. It supports the POSIX API by way of its BSD lineage (largely FreeBSD userland) and a large number of programs written for various other UNIX-like systems can be compiled on Darwin with no changes to the source code.Дarwin does not include many of the defining elements of macOS, such as the Carbon and Cocoa APIs or the Quartz Compositor and Aqua user interface, and thus cannot run Mac applications. Older versions supported some or all of 32-bit PowerPC, 64-bit PowerPC, 32-bit x86, and 32-bit ARM. An open-source port of the XNU kernel also exists for ARM platforms. 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. Hardware and software support Дarwin currently includes support for the 64-bit x86-64 variant of the Intel x86 processors used in Intel-based Macs and the 64-bit ARM processors used in the iPhone 5S and later, the 6th generation iPod Touch, the 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 TVs, the HomePod family, and Macs with Apple silicon such as the 2020 Apple M1 Macs, as well as the Raspberry Pi 3B. The hybrid kernel design provides the flexibility of a microkernel and the performance of a monolithic kernel.

MAC OS X OPERATING SYSTEMS HISTORY DRIVER

The kernel of Darwin is XNU, a hybrid kernel which uses OSFMK 7.3 (Open Software Foundation Mach Kernel) from the OSF, various elements of FreeBSD (including the process model, network stack, and virtual file system), and an object-oriented device driver API called I/O Kit. Darwin is now only available as source code. Minor updates were released as packages that were installed separately.

MAC OS X OPERATING SYSTEMS HISTORY INSTALL

Up to Darwin 8.0.1, Apple released a binary installer (as an ISO image) after each major Mac OS X release that allowed one to install Darwin on PowerPC and Intel x86 systems as a standalone operating system. In 2000, the core operating system components of Mac OS X were released as open-source software under the Apple Public Source License (APSL) as Darwin the higher-level components, such as the Cocoa and Carbon frameworks, remained closed-source. At the time, interim CEO Steve Jobs alluded to British naturalist Charles Darwin by announcing 'because it's about evolution'. In 1999, Apple announced it would release the source code for the Mach 2.5 microkernel, BSD Unix 4.4 OS, and the Apache Web server components of Mac OS X Server. This was developed into Rhapsody in 1997, Mac OS X Server 1.0 in 1999, Mac OS X Public Beta in 2000, and Mac OS X 10.0 in 2001. After Apple bought NeXT in 1997, it announced it would base its next operating system on OPENSTEP. The heritage of Darwin began with Unix derivatives supplemented by aspects of NeXT's NeXTSTEP operating system (later, since version 4.0, known as OPENSTEP), first released in 1989.

4.3 Darwin 16 onwards OS X rebranded into macOS.

4.2 Darwin 12вЂ“15 Mac OS X rebranded into OS X.

4.1 Darwin 0вЂ“11 and corresponding Mac OS X releases.
