Lesson 3: Use macOS Recovery Flashcards
What utilities are available when a Mac is started up from macOS Recovery?
The macOS Recovery system provides access to: • Restore System from Time Machine Backup • Install/Reinstall macOS • Get Help Online via Safari • Disk Utility • Startup Disk • Firmware Password Utility • Network Utility • Terminal • Reset Password
What two resources does the local hidden macOS Recovery HD need to reinstall macOS?
The local hidden macOS Recovery HD does not include the macOS installation assets.
Thus, reinstalling macOS from there requires high-speed Internet access and the ability to verify access to the installation assets.
Upgraded Mac systems are verified by entering the Apple ID used to download macOS Sierra.
Conversely, verification is automatic for Mac systems that included macOS Sierra when purchased new.
What methods can be used to create an external macOS installation disk?
A macOS installation disk, which includes the full macOS installation assets, can be created by using the createinstallmedia command-line tool found inside the Install macOS Sierra application.
