Active Reports for Macintosh OS supported browsers - Safari, Chrome, Firefox

Does anyone succeeded Creating Active reports and running them in Safari / Chrome/Firefox on Macintosh OS?

We tried it in Cognos 10.1.1 and got formal IBM-Cognos answer, that it is not supported in Safari, Chrome, Firefox.
We tried to run in MHT Firefox add-ons like unMHT or IE Tab Plus (works only on win32 OS
But with no success yet .

There is a sample in the internet under:

I’ve got the true Active Report .MHT file of this sample .
This Sample does run in above Macintosh scenarios , meaning – we are probably missing something . :’(

Does anyone tried it in earlier Cognos 10 releases?
Any other walk around would be mostly appreciated !!!
