Apple has hinted at WWDC2012 that Developer Preview 4 was close to the release candidate, and then announced that OS X 10.8 will be available to everyone through the Mac App Store next month for $20. Though DP4 is the most stable beta release yet, it still has a fair amount of bugs and is therefore only appropriate for developers to use.
System requirements:
- Mac with an Intel x64
- 2GB of RAM
- Language: Multilingual
OS X Mountain Lion DP4 VMware Image Changelog
- - Apple dropped support for 32-bit mode in DP2 of Mountain Lion, so make sure you keep the VMware Settings flagged as "Mac OS X 10.7 64-bit" otherwise no bootable medium will be detected. We are currently working on a workaround for this.
- - Comes with direct download links as usual, should be faster this time.
- - Completely Vanilla build. Drivers are purely patched Apple files.
- - Continued new packaging for smaller download.
- - Fresh installation of 10.8 DP4, everything was fixed during installation.
- - Make sure VT is turned on in your BIOS, if available.
- - No comment on AMD systems. Same applies as previously mentioned here.
- - Reasonably quick boot time, about 1 minute 15 seconds on average.
- - Recommended you run on the latest version of VMware, as that's what it was tested on, and apparently fixes Apple logo stalling.
- - Several driver patches to allow as best a universal build as possible.
- - Snappier system. Clicks receive response almost (if not) instantaneously.
- - We uploaded an updated VMware Tools to our Mediafire folder here. Hopefully these should work better than in the last 10.8 image.

Note: We don’t encourage downloading Apple software via file-sharing / torrent sites and run it in an virtualized environment under Windows. This guide is for informational purposes only. If you like OS X Lion, Get a Mac. It’s against the EULA for Mac OS X to run the OS in a virtual machine. The EULA for Mac OS X Server and Mac OS X Server/Client 10.7 allows you to run the OS in a virtual machine, but only inside OS X on an Apple hardware. This method is completely for testing and learning purpose.
