What are Mac Startup Keys
For a basic definition, using Mac startup keys simply means pressing a key or holding a combination of keys during startup to access certain features that are available at the time of booting.
Usually, your Mac works completely fine. Until the moment, it refuses to start up properly due to an unexpected system error, a poorly behaving app, a corrupted system component and some other threat. Also, if you consider a situation other than this, different people have different needs for starting up their computer.
As an example, you could be a geek who dual boots between OS X and Windows on a regular basis. On the other hand, there are users who want to boot a Mac from a disk other than their designated startup disk. Or, you are a casual user looking to isolate the cause of a software problem in the Safe Mode or, boot right into Recovery OS as the last option.
There can be several other scenarios too. Knowing about the Mac Startup keys will help you in all these situations.

- Command (⌘)—R: Recovery OS
- Command (⌘)—Option (⌥)—R: Internet Recovery OS
- D: Apple Hardware Test
- Option (⌥)—D: Apple Hardware Test over the Internet
- N: Boot from NetBoot server
- Option (⌥)—N: Boot from NetBoot server using the default image
- Media Eject, F12, mouse button or trackpad button: Eject removable media
- X: OS X Startup Volume- It will start up your Mac from an OS X startup volume when it'd otherwise boot from a non-OS X volume, like a Windows partition.

Some important things to remember
Create Mac Startup Usb
There are certain things which you should remember and know when you want to use the Mac Startup keys. These will make sure that you don't mess things up and also make you inform against the incoming issues. An aspiring pro should always acquire additional information. Take a quick look at these.
The Startup Sounds
You should never turn the volume all the way down before restarting your Mac. Hearing the startup tunes other than the familiar startup sounds is the initial step in determining what might be causing issues that your computer is experiencing.
Other than the diagnosis part, Startup sounds are also important for using some of the Mac Startup keys. So, you should always keep the Startup chimes up to the audible stages.
Startup Key Combinations Not Responding
There are some Mac notebook models on which the startup key combinations might not respond under certain situations. For example, if you are using an early-2015 12-inch MacBook model and have an Apple's Bluetooth keyboard connected to it, these key combinations will not work on your wireless keyboard.
To solve this problem, you can simply use the MacBook's built-in keyboard to get to Startup Manager, Recovery Mode, Single User Mode, Safe Mode and other features that are available at boot time.
Another solution is to connect any standard USB keyboard to your Mac via a USB-C adapter. This keyboard will make you able to use the Mac Startup keys without any hassle.
