Since the introduction of macOS, there have been booting difficulties. At times, this is due to a corrupted operating system; at other times, it is due to a crashed or malfunctioning piece of software or application that prevents the Mac from starting normally.
Not to add, hardware difficulties have been identified as a key cause of unexpected troubles on iMac or MacBook. However, do not worry; these expert techniques might assist you in resolving booting difficulties on your Mac and restoring regular operation. With that in mind, let’s begin the troubleshooting tutorial!
Disconnect All Accessory Devices
To begin resolving booting difficulties on your Mac, you should unplug any attached peripherals, including printers and USB devices. At times, peripherals connected to the computer might prevent it from booting. Therefore, give it a shot first to see how it performs.
Safe Mode on Your Mac
Another dependable method for resolving a Mac that would not start correctly is to use Safe Mode. For those unfamiliar with Safe Mode, it is intended to make it easier to evaluate whether the difficulties you are experiencing are related to the software that loads when the Mac starts up. Safe mode loads ONLY the absolute minimum services and applications necessary for Mac to boot correctly, with no third-party software or services permitted to start. If the problem is due to third-party software, the Mac should boot into Safe Mode.
To start your Mac in Safe Mode, power it down first. Then, while holding down the Shift key, restart your computer. Bear in mind that Safe Boot often takes some time to activate. If you are able to successfully boot the device into Safe Mode, the remaining steps are a matter of deletion. Delete the apps that start at login one by one and check to see if the system boots normally afterwards.
Reset the PRAM / NVRAM cache memory
Often, you may resolve your Mac’s booting difficulties simply by resetting NVRAM. When Mac appears to take an excessive amount of time to choose which disc to boot from or begins with the incorrect screen resolution, this solution makes things a lot easier.
Simply restart your Mac. Then, hold down the Command-Option-P-R keys while pressing the power button. Maintain a firm grip on these keys for approximately 20 seconds before releasing them.
Keep in mind that if you have an older Mac with a startup chime, you will need to hold down the keys until you hear a second starting chime.
Reset the system management controller
The System Management Controller is intended to manage a variety of critical parameters, including power management, fan control, and temperature monitoring. As a result, anytime anything goes awry, you’ll notice a variety of issues, including poor performance, excessive fan noise, and even failed booting. Therefore, attempt to reset SMC on your Mac.
On desktop Macs, turn off the machine and then unplug the power cord. Now, pause for fifteen seconds. Reconnect it and wait another 5 seconds. After that, power on the Mac.
MacBooks equipped with the T2 security chip (and other Touch ID-enabled devices):
Shut off the PC. Following that, press and hold the power button for ten seconds before releasing it. After a few seconds, hit the power button to bring your Mac to life. If the situation persists, restart the Mac. For seven to ten seconds, press and hold the right Shift key, the left Option key, and the left Control key. Press and hold it till the following phase. Now, press the Power button for seven seconds (while maintaining control of the other buttons – we understand this is a bit of a stretch for your fingers, but bear with us) and then release all of the keys. After the Mac boots, restart it.
MacBooks with non-removable batteries (no T2 chip): Turn off and then unplug your Mac. Then, while holding the Shift, Option, and Control keys, press and hold the power button. Hold the keys for at least 10 seconds before releasing them. Following that, plug in the power adapter and restart your Mac normally.
MacBooks with detachable batteries (no T2 chip): Switch off your Mac and then unplug the power cable and battery.
After that, press and hold the power button for 5 seconds. After that, release it. Following that, replace the battery and reattach the power cord. After that, power up your MacBook.
Reboot Your Mac in Recovery Mode
Recovery Mode is a final resort. Therefore, if none of the other methods has resolved your computer’s booting difficulties, give this one a try as well.
Restart your Mac and immediately press and hold the Command and R keys simultaneously until the Apple logo or spinning globe displays. When your Mac enters Recovery Mode, the Recovery Mode Utilities window should appear. You now have many options for restoring your machine, including restoring it from a Time Machine backup or reinstalling macOS. Choose your favourite choice and you’re ready to begin. If you choose to reinstall macOS, it will perform a clean instal, erasing any locally stored data, so exercise caution when selecting this option.
