Creating a never booted OS X template in vSphere 5.1 - Part 4 - Clone the DMG to a Sparseimage file using Disk and then install VMware Tools

The generated DMG image in the ‘Masters’ folder is not a copy of the original System DMG image from the ‘Library’ folder with a applied configuration.

To be precise it is a Read-Only DMG, with a ‘Apple Partition Map’ partition map scheme and it has been resized so that there is only around 100 MB of free space available in it... Continue reading

Creating a never booted OS X template in vSphere 5.1 - Part 1 - Introduction and reason for doing this

Save CPU time, disable Screen Saver on Mac OS X VMs

By default Mac OS X comes with the Screen Saver enabled, and set to kick in after 20 min. This is good in the physical world, to avoid screen burn in and somebody watching.
