Earlier, we reported that Parallels Desktop 8 had been updated to support running the OS X Mavericks Developer Preview – but for those who aren’t clear on how to make it work, or those who want a quick cheat sheet, Parallels has posted a full guide to installing Mavericks atop OS X Mountain Lion in a virtual machine.
Note that you mist have the latest update to Parallels Desktop 8 in order for this to work correctly. From Parallels:
Installing OS X 10.9 Mavericks Developer Preview in a blank virtual machine is not supported at this time.
However, you can upgrade an already existing OS X virtual machine to OS X 10.9 Mavericks Developer Preview. To do so, please follow these steps:
- If your virtual machine is running, shut it down and click Virtual Machine > Take Snapshot. If anything goes wrong, you will be able to roll back the changes.
- Click Virtual Machine > Configure > Hardware > Video and set 128 MB of video memory.
Once ready, start the virtual machine and download OS X 10.9 Mavericks Developer Preview.
Double-click the installation file and follow the on-screen instructions.
That’s all there is to it – with a bit of time and a dose of luck, you’ll be up and running Mavericks on your Mountain Lion install in no time!
