Hi all,
Thanks for posting! We’re aware that the macOS 10.15 developer beta build has just been released for testing a couple of days ago. As of yet, Axure RP is not yet supported on 10.15, but will be after there has been more time for testing, investigation, and fixing of any unexpected issues with the new OS.
As before with past OS updates, we advise against updating your OS to beta builds until they are stable and better supported, and for now recommend that you stay on one of the supported operating systems (macOS 10.9 through 10.14).
We’ll be working on testing and applying fixes for macOS 10.15, and these will be included in the release notes of builds that include the relevant fixes. You can check release notes via “Help > Check for Updates” and via our release history page. Thanks!
