Fusion 4.1 Allows Mac OS X Client Installations

With the release of Mac OS 10.7 Lion VMWare seem to have decided that all of Apple’s latest operating systems can be virtualized. VMWare Fusion 4.1. (released Nov 17th, 2011) thus allows the installation of all Mac OS X 10.5 Leopard, and 10.6. Snow Leopard versions; vulgo: the server and client editions.

Voicemail From Infinite Loop

The tiny downside is, VMWare seem to have gotten an urgent call from a fruity garage company in Infinite Loop soon after their release of VMWare Fusion 4.1. That’s why they issued VMWare Fusion 4.1.1 (released Nov 23rd, 2011) almost immediately, thus effectively reverting the capability of virtualizing the Mac OS X client versions.

Fusion 4.1.1 Update Bars Client Installations Again

That means: if you are running VMWare Fusion 4.1, you should consider not to upgrade to 4.1.1. If you have a Mac OS X client version virtualized it would not boot anymore after the update to Fusion 4.1.1. For all the others, VMWare does not distribute version 4.1 anymore, only 4.1.1. So you would have to search the net for download possibilities of VMWare Fusion 4.1. Luckily there are still legal sources for the 4.1 download. Update: the download link distributes version 3.1.1 (sic!) at the moment. You’re on your own finding the 4.1 download on the net (filename: “VMware-Fusion-4.1.0-529802-light.dmg”). Good luck.

[MacOS] VirtualBox 3.2 To Support Mac OS Guest on Windows Host [Update]

4 Replies

We suppose Apple will not like that, but Oracle’s latest version of VirtualBox 3.2 Beta 1 now supports virtualization of Apple’s Mac OS X.

Legal View

Although Apple’s license agreement clearly prohibits installing Mac OS X on other hardware than Apple’s, the screenshot shows that even the Windows version of Mac OS X is prepped to run Mac OS X as guest operating system.

On the other hand Apple’s license agreement is not valid in all countries. It cannot be applied in Germany and some other countries for example.

Technical View

To satisfy Apple’s Aqua binary encryption it is required to supply two operating system decryption keys (OSK0 and OSK1) to the kernel extension “Dont Steal Mac OS X.kext”. Although it is no secret that Mac OS can be run on PC hardware using decryption emulators like netkas’ fakesmc.kext, anyhow at the moment it is unclear if Oracle integrated those operating system decryption keys into VirtualBox.

[Update]

VirtualBox does not circumvent Apple’s binary protection. A VirtualBox developer confirmed, that Apple hardware is required in order to run Mac OS as guest in VirtualBox. So without tempering either with VirtualBox’ EFI or with Mac OS X it is not possible to run OS X in VirtualBox on a PC.

On the other hand a closer look at the EFI booter integrated in VirtualBox could reveal either how to modify PC Bios‘ to boot Mac OS X DVDs natively or how to expand our beloved Chameleon.
