• Apple states macOS Big Sur is engineered to take full advantage of all the capability and power of M1, delivering a massive boost in performance, astonishing battery life, and even stronger security protections. With M1, things users do every day feel noticeably faster and smoother. Browsing with Safari — which is already the world’s fastest browser — is now up to 1.5 times speedier at running JavaScript and nearly twice as responsive.
  • All of Apple’s Mac software is now Universal and runs natively on M1 systems. Existing Mac apps that have not been updated to Universal will run seamlessly with Apple’s Rosetta 2 technology. Additionally, the foundations of Big Sur are optimised to unlock the power of M1, including developer technologies from Metal for graphics to Core ML for Machine Learning.
  • macOS Big Sur will be available publicly from November 12, 2020.
