We're having a problem with Client Receiver v 11.5 & 11.6 on Mac OS X 10.8.2, our server is running Xenapp fundementals 6.0. We have several Macs on which it works just fine but have two where we can't launch applications. We can install the client, configure it no problem but when we launch an application it start off OK, you get an icon in the dock and the black rectangle connection box in the middle of the screen but after a few seconds this disappears to be replaced briefly by a Windows spinner then this goes as well and after a few seconds the dock icon goes as well and that's it.
We've tried uninstalling and reinstalling the client, doing a cleanup after uninstall, different versions, etc, etc. Logging on the receiver seems to be pretty much non-existent and the event logs on the server show nothing. None of the logs on the Mac show anything useful either. We're totally stumped so any suggestions/ideas would be gratefully accepted.
Launch the app through Citrix Receiver and ensure it is the active application (or click the 'Citrix Viewer' icon if it is already running but another app is active).

IIS logs look clean to me but I'm no expert, attached snippets cover a 'failed' app launch. STOP PRESS: We have found the answer. On the failing Macs, under System Preferences, Sharing, the Computer Name was blank. Added in a Computer Name, working!:) Now knowing what the problem was and having done some further research I'm a little irritated that there was no error message or warning apparent or logged anywhere to give us a clue as to what the problem was. No popup, no log entry, nothing in the server event viewer. Some sort of logging feature built into the receiver would have been a great help with this problem.

Edited by: Andrew Brazier on Jan 10, 2013 12:10 PM. Thank you for sharing your fix/find, Andrew. Looks like this has been a 'known' issue for a while as documented in the following Citrix KB article: 'Cannot connect to Store Using Mac Receiver 11.3' Obviously this issue occurs with up to version 11.7 of the Receiver for Mac. It would have been nice if the 'Symptoms' sections contained more info: Windows based PCs can launch published apps in the same environment just fine Some Mac Computers can connect and launch published apps successfully and some cannot (because, as we now know, the working Mac computers have a computer name designated and the non-working ones don't). You can enumerate applications When you attempt to launch a published application though, the viewer comes up, then goes away. Alternately, you may see the 'Starting application' with spinning status / progress indicator that eventually goes away.

In either case, the published application (and possibly desktop) does not launch. No errors or other indicators as to why from the client itself. No errors at the Web Interface or XenApp servers.
