FileMaker Inc today released FileMaker Pro 15.0.3, an update to address bug fixes and various compatibility issues.
You can read in the knowledge base about FileMaker Server 15.0.3 (6 fixes),
FileMaker Pro (Advanced) 15.0.3 (6 fixes) and FileMaker Go 15.0.3
As usual FileMaker provides updaters only for Windows and we miss the ones for Mac. So here are the links for Mac:
FileMaker Advanced 15.0.2 to 15.0.3:
FileMaker Pro 15.0.2 to 15.0.3:
Be sure to only apply them when you have the right 15.0.2 version before and FileMaker is not running.
