Your Mac Won’t Start at all
One day, you press the power button many times, even press and hold it for a while but your Mac refuses to start. In particular, the screen does not light up, the Apple logo does not show up, and no beeping sound. Here are some ways to fix this:
Make Sure Your Mac Get Some Battery Charge
The most common reason for this issue is that your Mac completely ran out of battery. In this case, you just need to plug the charger in, wait for a while, and your Mac will be able to start again. It is recommended that you let your Mac charge for 15 – 20 minutes before using it again. Make sure you disconnect all the external devices like a USB or eGPU in order to prevent excessive power consumption.
Check Your Charger/ Adapter
There are also chances that your charger/adapter may be broken so your laptop didn’t charge properly. You should check them carefully. You might want to try using another charger to see if it was the root of this problem.
Make Sure Every Cables are Connected Correctly
In the case that you are using a desktop Mac like the Mac Mini or Mac Pro, you should check that all its cables are correctly seated. For example, if you have a Mac Mini, make sure you connect the video-out cable securely to both the Mac Mini itself and the display. Furthermore, you can try unplugging all the cables and then plug them back in to ensure that they are securely connected.

If you have tried all these above but your Mac still refuses to start up, it may have issues with the mainboard. Unfortunately, there are not many things you can do now. Your best shot is to take your computer to the nearest Apple Center or Genius Bar for maintenance.
Your Mac is not Booting into macOS
In this case, your mac can start up when you hit the power button, but it does not boot in to macOS like usual. The problem might be caused by some software conflict or crash on your Mac system. You can fix it by following the below methods:
System Management Controller (SMC) is a subsystem of Mac computers based on Intel’s platform. SMC has the role of managing system temperature, battery charging, graphical display processing, startup and shutdown, and much more. Therefore, resetting SMC may fix the problem when your Mac won’t start.
Different Mac models have different ways to reset SMC. We have covered a guide on how to reset SMC on all Mac models here.
Boot Your Mac into Recovery Mode
If resetting SMC does not work for you, maybe your device’s drive is damaged. Fortunately, you can completely fix this problem by resetting your Mac in Recovery Mode. Here is what you need to do:
- Turn off your Mac completely by holding down the power button.
- Hold down Command + R, then press the power button again.

- Select Disk Utility> choose your Mac installation drive (usually Macintosh HD)
- Click on First Aid.

- Reset your Mac and use it like usual.
Reset PRAM or NVRAM
Your Mac stores certain settings in a special memory area even when it is turned off. Back in the day, PRAM referred to as a small amount of special memory in every Mac that stored information the computer needed before it loaded the operating system. On Intel-based Macs, this is stored in memory known as NVRAM; on PowerPC-based Macs, this is stored in memory known as PRAM.
Issues in PRAM or NVRAM can also cause your Mac not to startup properly. In this case resetting it may solve the problem. To reset PRAM and NVRAM, you need to perform the following steps:
- Turn off your Mac completely by holding the Power button
- Turn it back on.
- Press and hold the keys combination of Command-Option-P-R before you hear the startup sound.
- Hold the keys down until the computer restarts, and you hear the startup sound for the second time.
- Release the keys.

If other methods do not work for you, reinstalling the macOS may be the solution. Before you consider reinstalling macOS, make sure you’ve made multiple backups for your data.
Now to reinstall macOS, you need to boot your Mac into Recovery Mode that we mentioned. In the utility menu, you will see the option of “Reinstall macOS”. Select it to have your Mac automatically download the latest macOS installation files and reinstall its operating system. You can also restore your macOS settings from a Time Machine backup. If the operating system is corrupted and damaged, this process will replace it with a fresh, undamaged one.
