[MacOS] VMWare Fusion 4.1 Allows Installation of Snow Leopard Client and Leopard Client Versions

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] Using Windows 7 From The iPad With Parallels Desktop 6

Windows can eventually be used from the iPad. Users of Parallels Desktop 6 can seamlessly logon their Windows virtual appliance from the iPad. The required iPad app “Parallels Mobile” can be downloaded for free from the iTunes App Store (get it here). In the meantime check their vid:

[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.

[PS3] GeoHot Opens All HV’s SPUs / XorLoser Preps Manual

1 Reply

Obviously notorious George Hotz has managed to get all 7 SPUs of the Playstation 3’s CPU under his control. This means although he cannot access the CPU’s root key, he now can decrypt everything that’s going thru these SPUs like datastreams of (encrypted) commercial games.

The PPU is higher on the control chain then the SPUs. Even if checks were to be added to, for example, verify the hypervisor before decrypting the kernel, with clever memory mappings you can hide your modified hypervisor.

In the meantime another hacker going under the nick XorLoser has released a more detailed manual of how to use GeoHot’s exploitation files and how to do the glitching.

Besides that XorLoser maintains a plugin for reverser’s beloved Interactive Disassembler (IDA) that contains special PPC instructions for Xbox360 and PS3.

Congratulations to GeoHot. Kudos fly out to XorLoser.

[PS3] GeoHot Hacks PS3’s Hypervisor Protection

2 Replies

Notorious iPhone hacker GeoHot has succesfully circumvented the Playstation’s security system. According to his latest blog entry, he has dumped LV0 and LV1 code, thus allowing him to (theoretically) run code on the processor, bypassing the hypervisor.

The Playstation’s hypervisor is intended to run third party software (like Yellow Dog Linux) on a virtualized level, thus maintaining system integrity and protection of the host system. Within this virtualized environment arbitrary access to certain hardware devices has been disabled, thus allowing only basic access to the graphic processing unit (GPU) for example.

GeoHot seems to have broken the chain of trust. This means he can bypass the hypervisor to directly access hardware like the GPU with his custom code. Anyway he has not released any further information or proof of his work. But hey, it is not anyone, it is GeoHot, so it seems solid.

We compiled some links for people being interested in the hypervisor protection topic.

[MacOS] MacOS X as Guest OS on Parallels Server

Leave a reply

Today Parallels released the server version of their virtualization software. The MacOS X version supports MacOS X server as guest operating system.

[MacOS] VMWare Fusion to virtualize MacOS X

Leave a reply

VMWare has announced to support virtualisation of MacOS X Server. Although technically possible also for white box PCs this feature will only be included in the VMWare Fusion 2.0. The amount of virtual machines will only be limited by size of memory. The current beta version of VMWare Fusion 2.0 does not support virtualization of MacOS X yet.
