In June, Apple announced pre-release availability of iOS 13 and macOS Catalina (10.15). ClueTrust is working to verify complete compatibility with these versions prior to their release this fall.
However, as a rule, we caution against the use of pre-release operating systems for crucial work. Although we are unaware of any problems today that hamper the use of either Cartographica or CartoMobile, it is always possible to experience crashing and data loss with operating systems that have not been fully tested.
With that said, if you choose to experiment with iOS 13 or macOS Catalina and run into problems with our software, please don't hesitate to report the problem to us. We can't guarantee we will fix it during the beta period, but will work hard to have any compatibility issues resolved before the final release of the operating systems.
