I believe someone posted something similar. CS6 is not supported under El Capitan or Sierra.
You can try trashing your preferences but unfortunately, you're pretty much on your own here beyond that.
Trashing preferences doesn't help. Thanks
There is no solution for this problem??
We have the same problem.
Indesign doesn't even work properly..every tool takes for ever to load.
Search the forum for other threads. Some claim to have gotten CS6 to work with no issues with various solutions but you are still very much on your own here.
