Creating a never booted OS X template in vSphere 5.1 - Part 4 - Clone the DMG to a Sparseimage file using Disk Utility.app 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 2 - Creating an never booted DMG using System Image Creator

Start by downloading the newest version of System Image Creator (SIC) from GitHub https://github.com/mondada/SIC/archive/master.zip.

Unzip the archive, and you should have one (or more) BASH scripts.

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

The goal of this series of blog posts is to produce a never booted installation of OS X Mountain Lion, in a VMDK, which can be used as a template in VMware vSphere vCenter 5.1.

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

Examining Kerio Control Traffic Rules, by converting them to HTML
