"The current version of the EV3 Lab software is not compatible with the upcoming release of Apple’s operating system for Mac computers, called ‘Catalina’. We have therefore decided to replace the current EV3 Lab software and EV3 Programming App with a completely new app, called LEGO® MINDSTORMS® Education EV3 Classroom. Featuring a coding language based on Scratch, EV3 Classroom will initially launch for macOS in November 2019 and in spring 2020 for iOS, Windows 10, Android and Chrome. EV3 Classroom will offer a consistent experience, features, and content across all devices. The first release of EV3 Classroom will be in US English, followed by the other 15 EV3 languages in spring 2020."
