In this episode, Tyler gives a demonstration and walkthrough of macOS Recovery, a suite of utilities that can help resolve issues with your Mac and manage startup parameters. From within macOS Recovery, you can:

• Restore your Mac from a Time Machine backup or local snapshot
• Reinstall macOS
• Verify and repair the filesystem on your startup disk, as well as external disks connected to your Mac
• Erase and reformat your startup disk, as well as external disks connected to your Mac
• Change the startup security level and other security settings for your startup disk
• Access Terminal to issue commands directly to the operating system
• Mount your disk on another Mac connected via Thunderbolt to your Mac, allowing files to be created, copied, modified, and deleted as if the disk were an external storage device
