The 'classic' Mac OS is the original Macintosh operating system that was introduced in 1984 alongside the first Macintosh and remained in primary use on Macs until the introduction of Mac OS X in 2001. Apple released the original Macintosh on January 24, 1984; its early system software was partially based on the Lisa OS and the Xerox PARC Alto computer, which former Apple CEO Steve Jobs.
Developers can start building apps today and first system ships by year’s end, beginning a two-year transition
Cupertino, California — In a historic day for the Mac, Apple today announced it will transition the Mac to its world-class custom silicon to deliver industry-leading performance and powerful new technologies. Developers can now get started updating their apps to take advantage of the advanced capabilities of Apple silicon in the Mac. This transition will also establish a common architecture across all Apple products, making it far easier for developers to write and optimize their apps for the entire ecosystem.
Apple today also introduced macOS Big Sur, the next major release of macOS, which delivers its biggest update in more than a decade and includes technologies that will ensure a smooth and seamless transition to Apple silicon. Developers can easily convert their existing apps to run on Apple silicon, taking advantage of its powerful technologies and performance. And for the first time, developers can make their iOS and iPadOS apps available on the Mac without any modifications.
To help developers get started with Apple silicon, Apple is also launching the Universal App Quick Start Program, which provides access to documentation, forums support, beta versions of macOS Big Sur and Xcode 12, and the limited use of a Developer Transition Kit (DTK), a Mac development system based on Apple’s A12Z Bionic System on a Chip (SoC).
Apple plans to ship the first Mac with Apple silicon by the end of the year and complete the transition in about two years. Apple will continue to support and release new versions of macOS for Intel-based Macs for years to come, and has exciting new Intel-based Macs in development. The transition to Apple silicon represents the biggest leap ever for the Mac.
“From the beginning, the Mac has always embraced big changes to stay at the forefront of personal computing. Today we’re announcing our transition to Apple silicon, making this a historic day for the Mac,” said Tim Cook, Apple’s CEO. “With its powerful features and industry-leading performance, Apple silicon will make the Mac stronger and more capable than ever. I’ve never been more excited about the future of the Mac.”
Family of Mac SoCs to Deliver Powerful New Features and Best-in-Class Performance
For over a decade, Apple’s world-class silicon design team has been building and refining Apple SoCs. The result is a scalable architecture custom designed for iPhone, iPad, and Apple Watch that leads the industry in unique features and performance per watt, and makes each of them best in class. Building upon this architecture, Apple is designing a family of SoCs for the Mac. This will give the Mac industry-leading performance per watt and higher performance GPUs — enabling app developers to write even more powerful pro apps and high-end games. And access to technologies such as the Neural Engine will make the Mac an amazing platform for developers to use machine learning. This will also create a common architecture across all Apple products, making it far easier for developers to write and optimize software for the entire Apple ecosystem.
macOS Big Sur Enables Transition to Apple Silicon
In macOS Big Sur, Apple is offering a range of technologies to make the transition to Apple silicon smooth and seamless. With everything built into Xcode 12, such as native compilers, editors, and debugging tools, most developers will be able to get their apps running in a matter of days. Using Universal 2 application binaries, developers will be able to easily create a single app that taps into the native power and performance of the new Macs with Apple silicon, while still supporting Intel-based Macs. With the translation technology of Rosetta 2, users will be able to run existing Mac apps that have not yet been updated, including those with plug-ins. Virtualization technology allows users to run Linux. Developers can also make their iOS and iPadOS apps available on the Mac without any modifications.
Quick Start Program Lets Developers Get Started Today
Apple Developer Program members can start moving their apps to Apple silicon today by applying for the Universal App Quick Start Program. The program provides access to documentation, forums support, beta versions of macOS Big Sur and Xcode 12, and includes the limited use of a DTK, which will enable developers to build and test their Universal 2 apps. The DTK, which must be returned to Apple at the end of the program, consists of a Mac mini with Apple’s A12Z Bionic SoC inside and desktop specs, including 16GB of memory, a 512GB SSD, and a variety of Mac I/O ports. Developers can apply to the program at developer.apple.com, and the total cost of the program is $500.

QEMU is an open-source emulator for virtualizing computers. Unlike VMWare, it's able to both virtualize CPUs and emulate various CPU instruction sets. It's pretty powerful, free, and has a macOS port. There are alternate versions and different ways to install it. Still, in this example, I'm using Homebrew, a package manager for macOS/OSX that allows you to install software via the CLI and manage easily.
Now, this post wouldn't be very exciting if I tried this on my Mac Pro, but I decided to try it on my MacBook M1. Thus far, the community has succeeded in getting QEMU to install the ARM version Windows, so I decided to do the more silly path and get PPC and X86 working on Apple Silicon. I encountered very little resistance, which surprised me as I haven't seen/read anyone trying this route. It's surprsingly very usable but the usefulness is going to be limited. I was able to play Sim City 2000 on Mac OS 9.2 at a fairly high resolution. For the sake of brevity, I'm going to skip over installing Homebrew on an Apple M1, but you'll want to use the arch -x86_64 method, which requires prepending. I've gotten OS 10.0 and nearly gotten Windows 10 working on my M1.
Included below is the instruction for both Apple Silicon and Intel Macs.
Requirements
Over And Over (sisilicon) Mac Os X
- Basic understanding of the terminal in OS X/macOS
- Apple Silicon (M1) computer (or Intel) Mac
- Xcode
- xcode-select (CLI Tools)
xcode-select --install - Homebrew
Step 1: Install QEMU
This is the only step where Apple Silicon and Intel Macs differ. You'll need to install the x86 version of QEMU for the Apple silicon macs first.
Apple Silicon
x86 Intel Macs
Step 2: Create a disk image
The rest of the steps do not need any specification for M1 vs. Intel.
You can specify a route, but I just used the default pathing, the 2G = 2 GB below. You can get away with much less for OS X OS 9. If you'd like more space, change the size of the simulated HDD. .
Step 3: Launching the emulated computer and the tricky part: Formatting the HDD
Now that we have a blank hard disk image, we're ready to go.
Let's break this down so it's not just magic. The first command is the qemu core emulator, you can use things like 64-bit x86 CPU qemu-system-x86_64 or a 32-bit CPU qemu-system-i386 , but we're using a PPC, so we are using qemu-system-ppc.
Next, we're declaring PC bios with -L pc-bios, I'm unsure if this is necessary. This seems to be the default even in Mac QEMU. After that, the -boot flag declares the boot drive. For those who remember the days of yore, C is the default drive for PCs, D is the default for the CD-Rom like a PC. It's weird, I know. -M is the model flag. It's pretty esoteric, but QEMU uses OpenBIOS, and mac99 is the model for Beige G3s. The lowercase -m is memory, expressed in megabytes, but you can use 1G or 2G for 1 or 2 gigabytes like the format utility. -hda is the image we're using. Finally, -cdrom is the installer image
Step 3.5: Special considerations between operating systems
I discovered that OS X 10.0's installer has a significant flaw: It doesn't have a disk utility. The disk images are black disks thus have no file system. If you want to run OS X 10.0, you'll need to first launch an installer that can format HFS like OS 9 or later versions of OS X, run the disk utility, format the image and then exit out of the emulator. The process would look like this:
Then format the drive from the utility, quit the emulator (control-c on the terminal window).
Tiger and Leopard requires USB emulation so you'll need to add -device flags for a usb keyboard and a usb mouse, also both like a few extra -prom-env flags.
Power PC Leopard I can get to boot but it crashed twice during installs, this could be
Step 4: after the installer fininshes
You will end up seeing a failed boot screen after the installer finishes. This is normal. Either quit the QEMU instance or use control-c in the terminal to close it. Now that it's installed, we want to boot off the internal drive.
MacOS 9 seems to do slightly better when adding the via=pmu and specifying the graphics.

Step 5: mounting disk images
Over And Over (sisilicon) Mac Os Download
There's not a lot to do with an OS without software. You can mount plenty of disk image formats
Bonus round: Trying for x86 64 Windows 10
Step 6: Multi CD-Rom Installs or swapping Disk Images
Older applications and OS installers require mutliple disk images. This can be done from via the CLI inside QEMU.
On the QEMU window press:
- Control-Alt-2 to bring up the console
change ide1-cd0 /path/to/image- Control-Alt-1 to bring back the GUI
Thus far my Windows 10 experiment has been a lot less successful, I've gotten through the installer (it's unbearably slow) but it seems to hand on booting. It looks very feasible. I might have better luck using the 32 bit verison of windows.
