Darwin OS is the kernel develop by Apple that powers theirs latest computers and mobile devices. BSD is a unix system developed at Berkeley University. It is a very know Unix System. FreeBSD is an open source descendant of BSD unix. MacOS Big Sur elevates the most advanced desktop operating system in the world to a new level of power and beauty.

Rhapsody

Rhapsody

In the beginning of the project it was a fork of OPENSTEP. As far as I've been able to track down there have been 3 public releases of this OPENSTEP Darwin. And there have been several more public releases, up to and including OS X Server 1.0 which was based on the OPENSTEP kernel. Further complicating things, Darwin 0.1 reports itself as Rhapsody 5.3, while Darwin 0.2 and 0.3 report themselves as Darwin 0.2/0.3

From the source code of Darwin 0.1, The kernel is based on OS/F's 6.1 kernel. This is evident in boolean.h as an example:

The following is a table of versions I've been able to put together with information from the Rhapsody Resource Page, and a mirror of the Darwin Q&A.

Darwin 0.x can be built using a Rhapsody/OS X Server 1.0 binary system as a starting point. However when it comes to emulation and physical hardware the EIDE driver has a problem losing interrupts. It is not only a problem with Darwin/Rhapsody but on physical machines as well. This poses a challenge to 'white box' builders to this day. However the emulator Qemu 0.90 can run Rhapsody albeit with a busmouse driver.

For the sake of preservation, the preserved downloads from Darwin 0.1 are on archive.org. Some components in the 0.1 tars didn't make it to the 0.3 CD-ROM so they are needed to build a more 'complete' set.

At this moment I have the following version of Darwin setup to run on Qemu:

PowerPC

There has been tremendous improvements to Qemu, and it is now possible to install MacOS 9, and OS X Server 1.x, along with OS X 10.x. Darwin for the PowerPC doesn't have an actual installer on the discs, but rather you boot up into MacOS, and restore a disk backup from CD onto your target hard disk, and boot into that. Information can be found about the progress of the Qemu PowerPC on emaculation.com

Currently I have images of 0.3 & 1.0.2:

Crossover Mac

The process right now involves installing MacOS 9, as 8.6 included on the 0.3 currently doesn't boot. And likewise, the restore program on 0.3 won't run under MacOS 9, but the restore program from the 1.0.2 image will run on MacOS 9.

For the impatient, I do have the images already extracted and setup with Qemu

Currently there is no networking.

XNU

After the release of OS X Server 1.0, it was clear at this point that OS X was doomed, as 3rd party software vendors expressed no interest in porting applications to OPENSTEP/Cocoa API's. Instead Apple would have to go and create the Carbon framework, allowing traditional MacOS applications to use a subset of the toolbox API, and then be ported to OS X. Along the way the older OPENSTEP kernel was dropped in favor of a newer kernel based on Mach 3.0 and a C++ driver framework.

Darwin Based Os

The Darwin OS includes both the XNU kernel, along with all the free tools.

As far as I recall it started being fully distributed in Darwin 1.0, which was a PowerPC only release, while later releases included native support for the x86.

Versioning confusion

As mentioned over on this thread at nextcomputers.org, that although there was a released memo explaining the logic behind the version number changes so that way Darwin would match up to the build number of XNU, it lead to great confusion. However this letter at least sets it to the original intent.

The following releases can be downloaded here:

• Darwin 1.0 - OS X 10.0 DP 4 - Release notes
• Darwin 1.4.1 - OS X 10.1 x86 - Release notes
• Darwin 1.4.1 - OS X 10.1 ppc - Release notes
• Darwin 6.0.2 - OS X 10.2 x86 - Release notes
• Darwin 6.0.2 - OS X 10.2 ppc - Release notes
• Darwin 7.0.1 - OS X 10.3.1 unknown - Release notes
• Darwin 8.0.1 - OS X 10.4 x86 - Release notes
• Darwin 8.0.1 - OS X 10.4 ppc - Release notes

Compatibility is a mixed bag, and it was just as bad at the time, and on real hardware.

Darwin 1.4.1

Recently I've found that it will run using Qemu 2.7.I didn't have to do anything special and I've written about it here.

Darwin 8.0.1

Darwin 8.0.1 to run under Qemu 0.13.0. As far as I know 1.4.1, has some kind of CPU issue, and 6.0.1 and 7.0.1 all have ACPI issues.Installation is pretty simple, a config like this is more then enough to get going:
