So, we have many options here, from purist to practical and all in between. But I feel that QEMU is a way to extend the future on Mac OS 9 via emulation. Yes, we will keep the G3/G4 hardware alive for as long as we can. the reason I have ventured into the 'QEMU' thing was expressed by member FBz 100% correctly. OK, I'll get off the tangents.īack to the topic. Sure DOS was great, sure it ran stable, and setting up business networks and Novell servers, Word perfect 5.1 as a production marvel with virtually no maintenance. Even the G3/G4 hardware of the era became a perfect balance of 'art' and 'engineering', pushing all sorts of envelopes, while IBM PCs were just kinda boring. That being said, Mac OS 9 in particular, has always had a place in my heart, and will always be unique, there is a perfect balance of art and functionality that is intrinsically 'baked' into it's core. These efforts are based on finding solutions, not replacing or core values.Īs you guys know, or may not know, I am an old guy old and I have been exposed to computers from Commodore PET, IBM mainframes, and Unix terminals in my teens to contemporary PCs and Macs today. macOS Version Place 10.15 2019 Catalina 10.14 2018 Mojave 10.13 2017 High Sierra 10.12 2016 Sierra OS X Version Place 10.11 2015 El Capitan 10.10 2014 Yosemite 10.9 2013 Mavericks OS X Version Jungle Cat 10.8 2012 Mountain Lion 10.7 2011 Lion 10.6 2009 Snow Leopard 10.5 2007 Leopard 10.4 2005 Tiger 10.3 2003 Panther 10.2 2002 Jaguar 10.1 2001 Puma (code name) 10.After getting a few PMs from our core members, I felt I should explain my affinity for always pushing the Mac OS 9 realm (and OS X for that matter) into unsanctioned areas.

Starting with Version 10.2 (Jaguar), the animals became the official product name until Version 10.9 (see below). Faster Cats!Mac OS X versions were internally code-named after jungle cats. Programs can also be developed in Java and BSD.

Carbon is used for applications that can run on both OS X and earlier Mac OS machines, and Classic is the API prior to Mac OS X. Cocoa is the native OS X interface, derived from OpenStep.

Programming EnvironmentsThere have been five programming interfaces (APIs) for writing Mac OS X applications. However, PowerPC applications could run on Intel Macs via an emulator (see Rosetta). Classic was not preloaded on new Macs, but was available for installation from the system disks.In 2006, Apple switched from the PowerPC to the Intel platform, and Classic support was dropped in the Intel version of OS X. Legacy SoftwarePrior to Mac OS X 10.5 (Leopard), OS X ran legacy OS 9 and earlier applications via its Classic software, which was a full copy of OS 9 that ran as an OS X process. The heart of OS X is the open source, POSIX-compliant Darwin kernel, which includes an enhanced BSD 4.4 operating system and Mach 2.5 microkernel. For the first time, the rich set of Unix commands became available to all Mac developers (A/UX was an earlier Unix OS for the Mac but was not widely used).OS X added protected memory, pre-emptive multitasking, multithreading and symmetric multiprocessing (SMP) to the Mac world. Based on Unix and featuring an entirely redesigned user interface, OS X was a major departure from the previous OS 9 system. See macOS and Sierra.OS X Server was introduced in 1999, and the client version came out in 2001.

Starting in the fall of 2016, Version 10.12 uses the rebranded 'macOS' moniker and not OS X. (Mac OS 10) The current operating system from Apple for the Mac family.
