Since Self Service no longer supports .ICNS files and now uses .PNG files i have to convert all my icons to PNG.
When i added new software to my JSS I take the icon out of the Application .app and use that for Self Service.
I have therefore made an App which you can use to convert .icns to .png
I have also added the ability to convert .plist files for XML to Binary and vica versa rather than having to use terminal, simply drag the file into the App and click the convert
If anyone would like a copy of this app email me.
