Important Information: EV3 on MacOS

Important Information: EV3 on Mac Operating Systems (MacOS)

Dear Teams and Partners,

LEGO Education has an important announcement for FIRST LEGO League teams working on Mac Operating Systems (macOS). Please read the message below carefully and share with your teams where necessary.

The current version of the EV3 Lab software is not compatible with the upcoming update to macOS, called Catalina. We are therefore introducing a brand-new EV3 app in November 2019, called LEGO MINDSTORMS Education EV3 Classroom. Based on the SPIKE app, EV3 Classroom will feature a coding language based on Scratch that we are confident will unleash the full potential of EV3 in the FIRST LEGO League program. The first release of EV3 Classroom will be in US English, followed by the other 15 EV3 languages in spring 2020.

To continue to enjoy an uninterrupted EV3 experience and to avoid losing your programs, we strongly recommend that you do not update to Catalina until the end of the FIRST LEGO League season in July 2020. If you have already updated to the new OS, please contact T​​echnical Consumer Service at to discuss how we can help you during this transition period.

For further questions and support, we encourage you to reach out to Technical Consumer Service using the link above.
