Running Mac OS X Snow Leopard Emulator

Mac OS X Snow Leopard, released in 2008, was a significant update to Apple's operating system, introducing a new kernel architecture and improved performance. Despite this, Apple clarified soon after releasing its first Developer Preview (DP) at WWDC 2008 that PowerPC Macs would not be supported once Snow Leopard went on sale.

However, with minor modifications, these DPs can install and run on later G4 and G5 PowerPC Macs. The kernel flags -force64 arch=i386 are useful on AMD CPUs where 32-bit kernel space and 64-bit userland is wanted. It's worth noting that this is the only 64-bit kernel space kernel for Snow Leopard on AMD CPUs at the time of writing.

Clouded Leopard: A Nickname for Snow Leopard DPs

The Mac OS X Snow Leopard Developer Previews (DPs), released between June 2008 and late 2008, are often referred to as 'Clouded Leopard'. These DPs were found to be Universal Binaries, allowing them to run on both PowerPC and Intel-based Macs.

Running Snow Leopard on AMD CPUs

If you're looking to run Snow Leopard on an AMD CPU, there are several kernels available that can help. For example, FX-Series CPUs work with the kernel flag arch=x86_64. Additionally, ironzovka's Original Kernels 10.7.3 and 10.7.4 allow for running in 32-bit mode on many SSSE3-less CPUs.

Troubleshooting Issues

Some users have reported issues with graphics and rebooting when running Snow Leopard on AMD CPUs. However, there are patches available to help resolve these issues. For example, the patch found here can help with issues with Safari and the App Store.

It's worth noting that some users have also reported issues with USB 3.0 plugs randomly restarting their Macs. Again, there may be patches available to help resolve this issue.

Overall, while running Snow Leopard on AMD CPUs can be challenging, there are several kernels and patches available that can help make the process smoother. By using these tools, you can enjoy the benefits of Snow Leopard's improved performance and features even if your Mac isn't officially supported by Apple.
