Turns out if you just hit CANCEL on the prompt to choose your identifying certificate and then create permanent exemption the Unisphere webpage works fine on mac browsers.
Hello, I cannot access Unisphere from my Mac with Safari, Firefox, or Chrome.  I am prompted to identify myself with a cert which is auto populated with my machine info.  I then click continue and add permanent exception for the site.  I then get this error:  Peer does not recognize and trust the CA that issued your certificate. (Error code: ssl_error_unknown_ca_alert)  Accessing Unisphere from a Win 8 VM on Fusion with Chrome, Firefox, and IE all work fine.  I dont understand why on the Mac Im prompted to choose a cert to identify myself ??
