Apple filed two trademark applications with the United States Patent and Trademark Office on the first day of WWDC 2020.

The first of these trademark applications is for the A12Z Bionic system-on-chip that is used in iPad Pro 2020. The same SoC will also be used in the upcoming Mac mini that will be provided to select developers as 'developer transition kits'. The A12Z Bionic system-on-chip was demonstrated running macOS Big Sur during WWDC 2020 event. It ran the operating system without any issues, including x86 emulation for non-native apps and games on the ARM-based processor.
