Schools with Macs capable of upgrading to OS 13.x (Ventura) should avoid this upgrade as it will cause compatibility issues with the Cambium Assessment (CAI) Secure Browser used for student interim and summative testing. Automatic updates of Mac devices should be disabled to avoid inadvertent upgrading to an unsupported OS. The supported devices page of the Online Technology Guide will be updated later this winter when support of macOS 13.x (Ventura) is confirmed.
