We support the most recent major OS version number (Mac OS 14 Sonoma) and its predecessor.


Your Mac device should be running at least macOS 13: Ventura (Rome) to use URC TV smoothly, and you should also keep your web browser (ideally Google Chrome) updated to the latest available version. 

At least 8GB of RAM is required, as RAM is a shared resource across all applications on your computer. Closing down additional applications and minimising the use of browser plugins will all help if your device is low on RAM, as will a restart if your computer has been running without a shutdown for a long time. 


Your internet connection must also be sufficiently strong. You can learn how to test your internet speed here.


If you are using Airplay to cast to Apple TV, make sure you upgrade to the latest tvOS (17) or the best experience.
