Solution 1: Make Some Simple Checks
At times, iMac/MacBook Air/MacBook Pro won’t turn on happens due to some simple reasons. For example, you are using a wrong or damaged cable or adapter. Or perhaps you don’t power on the device properly. So, let’s first make some simple checks.
Listen to the Sound and Watch the Indicator Light
Press the Power button for your Mac computer and then listen to the sound it makes including the sound from the fan, the hard drive, and other startup sounds.
At the same time, you need to watch the lights from a backlit keyboard, caps lock key, and sleep indicator light.
If you can’t hear the sound and see the lights, it means that your Mac has no power. Then, you need to check the power connection issue.
Check Your Power Connection
The first thing you need to check is the power outlet. You can connect another device like a lamp to the power outlet to see whether it can work.
If the power outlet is OK, you can check whether your MacBook is plugged incorrectly. You can just unplug and then re-plug the cable and adapter to have a try.
Besides, you can also perform a power cycle by pressing and holding the Power button for about 10 seconds and then releasing it.
If you are using a laptop, you need to make sure that the battery is charged. You can charge your Mac laptop for a while and then press the Power button to see whether it can boot normally.
Check the Cable and Adapter
You can go to check whether the cable and adapter are damaged or you are using a wrong cable and adapter.
You can try another supported cable and adapter to see whether you can boot your MacBook normally. Or perhaps you mix the cables and adapters you have, and you use an incorrect cable and adapter for your MacBook. Just make a check to rule out this issue.
Check the Display
If you are using an external display, you need to guarantee that the display is turned on successfully. For example, you can check the power cable and the power button. You also need to turn on the brightness for your Mac display.
Unplug All Accessories
The connected accessories can also cause the Mac won’t boot issue. You can disconnect all accessories and then boot your Mac again to see whether everything goes back to normal.

NVRAM, which is also known as nonvolatile random-access memory, is a small amount of memory that can be used to save certain settings like sound volume, display resolution, startup disk selection, time zone, and recent kernel panic information, and access them quickly. PRAM, which is also known as Parameter RAM, is used to store similar information as NVRAM.

- Press and hold these four keys at the same time: Option, Command, P, and R, and then turn on your Mac computer.
- Release the four keys about 20 seconds later. During this process, Your Mac computer may restart.
- If your Mac can play a startup sound, you can release these four keys after you hear the second startup sound.

Solution 3: Reset SMC
The full name of SMC is the system management controller. Resetting it can solve certain problems related to power, battery, fans, etc. You can try this method to solve the Mac won’t boot issue.
