Toon boom informed us a while back not to use mavericks as they had some issues with it working with SBpro. I don’t remember any update regarding that situation.
Is it ok to use mavericks with SBpro now . Anyone using mavericks and had issues ?

SBPro works with Mavericks (Version 4.1). It was only the 4.0 version that had an issue with the licensing on Mac.
