MCUXpresso IDE is currently supported on macOS 10.12 to 10.14.
In macOS 10.15 (Catalina), Apple have introduced a new additional "signing" mechanism for software that is download outside of the Apple App Store, know as "Notarization". Currently MCUXpresso IDE for macOS is signed using NXP's Apple Developer ID, but has not yet gone through Apple's notarization process. This means that by default you will not be able to install if you are running macOS 10.15.
Therefore we currently do not claim to officially support MCUXpresso IDE on macOS 10.15. We expect to make a version of MCUXpresso IDE that has been notarized during 2q2020. However in the meantime, you may be still be able to install and use current IDE releases using the following instructions.
which is because the IDE installer is not notarized. Now open up "System Preferences" and select the "Security and Privacy" option:
and select the "Open Anyway" option for the MCUXpresso IDE installation pkg file.
