Hi,
there will be very soon a new krpano release with MacOS Sierra support (the Sierra support itself should be ready, but I still need to do some testing and finish also some other things).
The problem itself was Apples own compatibility and security stuff - not a single code line in krpano itself had to be changed or updated - only the build system, the minimum SDK version and the code-signing had to updated...
But the price for supporting MacOS Sierra was to give up support for older OSX versions, the officially supported new minimum OSX version will now be 10.9...
'Upward-compatibility' and 'Mac' are two things that don't go very well together!
For more information about Apples new Gatekeeper/Security stuff ('AppTranslocation') in Sierra please see also here:
