Processor emulator using a portable dynamic translator. QEMU emulates a full system (usually a PC), including a processor and various peripherals. It can be used to launch a different Operating System without rebooting the PC or to debug system code. Mar 21, 2020 It is the primary OS for Apple’s Mac computers. It is the second most widely used desktop OS, after Microsoft Windows. In this article, we’ll look at how you can run or install macOS on QEMU, accelerated by KVM. For this setup, we’ll use the macOS-Simple-KVM project code available in Github to run macOS on KVM / QEMU. For you to be able. Mac OS 10.4 (PowerPC) in QEMU. Now that Apple has ended supporting PowerPC applications having Mac OS 10.4 around can be a life saver. With it you can continue to use your favorite PowerPC applications. Suggested command-line: qemu-system-ppc -hda image file -boot c -netdev user,id=mynet0 -device rtl8139,netdev=mynet0.
Mac OS 10.4 (PowerPC) in QEMU
Now that Apple has ended supporting PowerPC applications having Mac OS 10.4 around can be a life saver. With it you can continue to use your favorite PowerPC applications.
Suggested command-line:
To boot in verbose mode add this:
This makes sound work, but it doesn't work on Mac OS 10.4.11. It does work with Mac OS 10.4.3:

Notes:
To prevent the guest from freezing turn off all setting in the Energy Saver pane in System Preferences. Set the sleep and display sliders to Never. Uncheck the 'Put the hard disk(s) to sleep when possible' checkbox.
It is also suggested to turn off the screen saver. Open the the 'Desktop & Screen Saver' pane in System Preferences and slide the 'Start screen saver:' slider to Never.
Issues:
Sound currently doesn't work very well. It might have static to it like playing a vinyl record.

- 1QEMU on OS X (macOS) hosts
While QEMU's main host platform is Linux, it is also supported on operating systems for Apple's Mac computers (known as OS X or macOS). The official support policy covers the last two released versions of OSX; QEMU might work on older versions, but it is not guaranteed and it might not even compile on older versions.
Please note that fewer developers work on QEMU for Mac hosts, so it might be less stable (but I don't think it is). If you can replicate a bug on a Linux hosted QEMU before reporting it, this is helpful as it means a wider set of people might look into it.
Some system emulations on Linux use KVM, a special emulation mode which claims to reach nearly native speed.KVM is mainly used for x86 (32 and 64 bit) emulation on x86 hosts running Linux. Should you want to run Qemu with KVM support on a G5, depending on your distribution, you might have to compile your own kernel with KVM support.There exists a port of QEMU to Hypervisor.framework (a kernel module from Apple which is similar in spirit to KVM), but unfortunately it is not included in upstream QEMU.
Building QEMU for OS X
The system requirements are:
- One of the last two most recent versions of OS X (currently that's 10.13 or 10.14)
- The clang compiler shipped with the version of Xcode for that OS X. GCC might also work, but we recommend clang
Additional build requirements are:
You may find it easiest to get these from a third-party packagersuch as Homebrew, Macports, or Fink.
After downloading the QEMU source code, double-click it to expand it.
Then configure and make QEMU. The target-list option is used to build only the machine or machines you want. If you don't specify it, all machines would be built. Probably not what you want.
This way doesn't require you to wait for the configure command to complete:
If your system has the 'say' command, you can use it to tell you when QEMU is done
You can use './configure --help' to see a full list of options.
Here are all the currently available machines:

Qemu PPC For OSX [E-Maculation Wiki]
We recommend building QEMU with the -default compiler provided by Apple, for your version of Mac OS X (which will be 'clang'). The configure script will automatically pick this.

Errors on old compilers
Note: If after the configure step you see a message like this:
you may have to install your own version of gcc. You can build it from source (expect that to take several hours) or obtain third party binaries of gcc available from Homebrew or MacPorts.
You can have several versions of GCC on your system. To specify a certain version, use the --cc and --cxx options.
Build with LLVM/Clang 7
If you need to compile with newer versions of clang (to get f.i. AVX/AVX2 support), you can install llvm through e.g., brew.
Note that building for machines with CPUs supporting such extensions will exclude running your binary on earlier machines.
