The latest and greatest (as of this writing) version of the Apple MAC OS (Mountain Lion) removes some support for versions and editions that UCS Manager requires for full functionality. This tip represents an UNSUPPORTED set of instructions to restore full UCS Manager functionality.
The details in this tip were provided by Derek Cox at Emory university. Thank you for sharing.
Since the steps below detail how to make UCS Manager and the MAC OS work in an unsupported manner, I feel like to need to remind you that this is NOT an official Cisco web site or resource. This page as with all information found on this site, http://ciscoquicklinks.com does NOT take any legal responsibility for the results of performing any of these tests in your environment. The content of this page and site including may include errors and inaccuracies and are provided for informational purposes only and should be considered "use at your own risk".

If you completely re-install your Mac with Mountain Lion, the KVM in UCS will not work anymore. The reason is that Apply only supports 64 bit Java 7 with the latest update in OSX 8.0.1 (Mountain Lion). They dropped all 32 bit and Java 6 support. Unfortunately, the latest versions of UCS Manager GUI supports 32 bit Java 7 (or earlier). In addition the KVM applet only supports 32 bit Java 6 (or earlier).
- Install Java 6. You will not have a preferences pane and the browsers will not see Java. Apple does not support this on Mountain Lion but should work. http://support.apple.com/kb/DL1572
- Run the commands listed in the following KB article to revert back to Java 6. Again this is not supported on Mountain Lion but should work. http://support.apple.com/kb/HT5559
- Install Java 7 on top of all the work above. UCS Manager with full remote KVM and remote Media fuctions should work great. http://www.java.com/en/download/mac_download.jsp?locale=en
