Onion College is the garden of onion mathematics. The mobile phone client has iOS and Android versions, while the computer client has only Windows version and no mac version. Therefore, it is impossible to download the official client of Onion College on mac. If you really need to use it on a mac, you can download a mobile phone simulator software, and then download the onion academy to log in. Onion College is a favorite online education brand for both students and teachers. It uses cognitive science and intelligent technology to provide online courses, intelligent exercises, problem analysis and learning situation analysis for teachers and students. We have long been committed to systematically promoting the balanced development of education, so that every child in China can get high-quality educational resources.
