You can find the version number of the currently running Server.app by (in Server.app) selecting the entry in the top left of the window (under the heading SERVER) which corresponds to the name of your computer. Then in the main part of the window under the Overview tab it will say in the software section what version of the Server software you are using.
The latest version is Server 2.2.1 (Build 12T162).
I have had no problem running DeployStudio 1.5 and 1.6 with the above version of Server.app
I'll make a note of this for future reference. Much appreciated.
we are not running a server version as yet but intend to. We will be having 90 macs soon and need a way to manage/deploy them hance the interest in deploystudio. I was looking on the apple site and I see we can get the server app for approx £14 but I could not see anything in the guides, info or whatever to say what the exact version was. Thanks for your help with this.
