New Macs with Apple Silicon will feature revamped macOS boot and recovery features, based on iPhone and iPad Secure Boot. Although it uses the same boot process, it has been enhanced for Mac and will support multiple macOS installs, multiple versions of macOS, and recovery flows.

Advanced boot options such as holding down shortcut keys to boot into recovery mode, target disk mode, or single-user mode, will work without remembering any shortcut keys. All these start-ups keys will be replaced with user interface interactions. Users will simply need to press and hold the power button, or Touch ID button, on their Mac to bring up the new Startup options. Users will still be able to use shortcut keys when the new Startup options load, but they will not need to press and hold any combination of keys to boot into a particular mode.
