If I had to copy-paste to my client the list of browser that are supported with the viewer, it would be very useful for me. I know it's IE9+ but what about Chrome, Safari, Opera, Firefox, etc.? Thank you in advance.
Here's the list:
Chrome >= 27
Firefox >= 22
IE >= 9
Safari >= 6.0.4 (Snow Leopard >= 5.1.9)
We'll be adding this to our System Requirements topic soon, too. That's where we'll always keep the latest.
A lot has been going on since you wrote. I'm glad to tell you that this information has been included in our help center. Here you can access to latest Indigo Studio system requirements.
Best regards,ClaudiaIndigo Studio Team
