Earlier this month Apple released the updated Mac OS 10.15 (Catalina) operating system, which if installed on student Mac test devices, will cause the AIR Secure Browser to fail to launch. School TAs and/or Technology Coordinators should not update any Mac computers being used for testing until the AIR software review team has confirmed Mac OS 10.15 is compatible with AIR testing systems. Another announcement will be posted once compatibility has been confirmed.
