Just wanted to share a post from our forum with the current status of Mac OSX 10.8 support (confirmed by the client):
-----------------------------------------------------------------------------------------------------
We have done a few more tests on clean OSx 10.8 with latest updates, and SpotEditor seems to be working fine as-is (the same copy as in our free 360 viewer download).
To make it work on OSx 10.8 we have installed the latest X11 2.7.4 via http://xquartz.macosforge.org/landing/
And you also need to install Mono framework using this link (same as as per our readme in the free download):http://download.mono-project.com/archiv ... in.x86.dmg
Also, it looks like you have to restart your computer after initial installation of X11 on fresh Mac OSx for it to start working with our app.
