Why My MacBook Won't Turn on After macOS Monterey Update

Mac Users may have to experience a bizarre MacBook experience after installing the latest macOS Monterey update. You might have been looking forward to enjoying the new features and improvements of the latest operating system, but instead, you are left with an unresponsive device.

But why does this happen? There could be several reasons why your MacBook won't turn on after the macOS Monterey update, and some of them are mentioned below:

Software Conflicts

Software conflicts are among the most common reasons your MacBook won't turn on after the macOS Monterey update. When you update your operating system, the odds are that some of your existing software might not be compatible with the new update. This results in system instability, crashes, and in some cases, the inability to turn on your Mac.

Battery Issues

Another reason your MacBook won't turn on after the macOS Monterey update could be battery issues. If your MacBook's battery is considerably low, it might not have enough power to turn on. Additionally, if your MacBook's battery is old, it may not be holding a charge as well as it used to, leading to the inability to turn on your MacBook.

Hardware Problems

Apart from software-related issues, several hardware-related reasons could cause your MacBook not to turn on after updating to the macOS Monterey. One of the common causes is a faulty power supply, which can result in insufficient power supply to the MacBook. Additionally, a faulty logic board or a defective hard drive can also cause the MacBook not to turn on.

Installation Errors

Installing errors could be another reason your MacBook won't turn on after the macOS Monterey update. If the macOS Monterey update is stuck, causes system instability, leading to your MacBook not turning on. Additionally, any interruptions during the update process, such as a power outage, could cause problems with the update.

Corrupted System File

Last but not least, a corrupted system file or software conflict may also interrupt the normal booting of Mac after the macOS Monterey update. This can happen if the update process is interrupted or not completed successfully, leading to errors in the operating system. Additionally, incompatible software or drivers can cause conflicts with the updated macOS, resulting in the MacBook not turning on or freezing during startup.

Reinstalling the macOS Monterey in recovery mode is a common solution to fix the MacBook that won't turn on after the macOS Monterey update issue and can be done using the below-mentioned easy and quick steps:

Step 1. Restart your MacBook and simultaneously hold down the "Command + R" keys until the Apple logo appears.

Step 2. This will take you to the macOS Utilities menu. From here, select "Reinstall macOS" and click "Continue".

Method 2. Try to Boot Mac into Safe Mode

Mac Safe Mode is a feature in macOS that allows users to boot their Mac with a minimum set of software and drivers. When a Mac is started in Safe Mode, it runs a series of checks and only loads essential software components, preventing third-party extensions and login items from running.

It can be useful in troubleshooting issues caused by third-party software, as it can help isolate the problem and allow users to remove or repair the software causing the issue. It can also help in the normal booting of Mac after the macOS Monterey update using the easy-to-follow steps mentioned below:

Step 1. Boot up your Mac by pressing the "Power" button.

Step 2. Press and hold the "Shift" key when the Mac starts.

Step 3. Hold the "Shift" key until the login screen appears, then release the key.

Method 3. Reset the PRAM

PRAM stands for Parameter Random Access Memory and is a small amount of memory that stores system settings on a Mac. These settings include information about the startup disk, display resolution, time zone, volume, etc. Resetting the PRAM on your Mac can help resolve issues related to these settings. It involves freeing up RAM on Mac and resetting it to its default values.

This can be useful when a Mac is experiencing problems such as a frozen screen, the inability to adjust volume or screen resolution, or other strange behavior like Mac not turning on after macOS update Monterey. To reset PRAM on Mac, follow these steps:

Step 1. Shut down your MacBook.

Step 2. Press and hold the "Power" button for 10 seconds, then release it and wait a few seconds.

Rebooting a Mac from the installer is a method of fixing booting issues when the Mac won't turn on after updating to macOS Monterey. It involves using the macOS installer on a bootable USB drive or external hard drive to hard restart your MacBook and perform repair operations.

This method is necessary when the previous methods, such as safe or recovery modes, fail to solve the issue. You can access additional tools to diagnose and repair your Mac's startup disk by rebooting from the installer.

Step 1. Start by turning off your MacBook completely and plugging it into a power source.

Step 2. Press and hold the power button until the Apple logo appears on the screen. Then, release the power button.

Step 3. Hold the "Option" key until you see the Startup Manager screen.

Step 4. Select the macOS Monterey Installer from there, and click on the arrow to boot your Mac from the installer.

It is the least favorable option and is used only in the hour of need when other solutions fail to fix the issue. It can help clear any temporary glitches or bugs preventing the device from functioning properly.

However, it should be noted that a hard reset can also result in data loss or damage to the device's internal components, so it should only be used when necessary. To perform a hard reset on Mac, you can follow these easy and simple steps given below:
