Command + V boots your Mac into what is called Verbose Mode. Using this key combination will cause your Mac to become very verbose on startup and will show a terminal-like interface while booting. It will contain information important to startup, allowing you to diagnose startup problems by seeing any errors that may be occurring during startup. Verbose mode exits automatically when the computer's startup process progresses sufficiently and the blue screen appears.
To get back to OSX, Boot Camp: Set the default operating system , or shutdown your Mac and hold Alt/Option key when powering up the Mac and choose the OS you want to start.
Keep holding the keys until your Mac reboots itself and you see the Apple logo appear and disappear a second time. At this point, you can release the keys and your Mac should boot as normal. Note that settings such as resolution and system speaker volume will be set to defaults, so don&rsquo t be startled if your Mac&rsquo s sound effects are a bit louder on the second boot.
To use Target Disk Mode, reboot your Mac and hold down the T key as soon as you see the Apple logo. Keep holding until you see a white FireWire or Thunderbolt logo appear on the screen (depending on your Mac&rsquo s hardware capabilities). You can now directly connect your Mac to another Mac with a FireWire or Thunderbolt cable and access the first Mac&rsquo s drive. When you&rsquo re done, unmount the first Mac&rsquo s drive from the second Mac in macOS and press and hold the first Mac&rsquo s power button until the system powers off.
Select Disk Utility and press Continue. Then, from the Disk Utility sidebar, select the volume that you&rsquo re using and choose File Mount from the Menu bar at the top of the screen. Enter your admin password when prompted. Next, quit Disk Utility and choose Terminal from the macOS Utilities menu in the Menu bar. From there, you can enter UNIX commands just like in Verbose Mode. When you&rsquo re finished, restart your Mac.
The Mac Startup Manager will update as needed, so if you add or remove bootable drives or devices on your Mac, the list will automatically display the current options. You can use your mouse, trackpad, or keyboard to select the desired drive, and either click on its upward arrow button or press Return once you&rsquo ve made your selection. As long as the Mac is compatible with the operating system contained on the selected drive, your Mac will continue booting the designated operating system.
The Mac Startup Manager works great if you have a number of boot options from which to choose, but your Mac also recognizes a few additional startup keys that direct it to boot immediately from a specific source. These keys include holding the C key during boot to boot directly from an inserted CD, DVD, or bootable USB drive on older versions of macOS, and holding the N key to perform a NetBoot to a compatible network server.
