In contrast to what many may think is responsible for the frequent crashes of their MacBook Pro, it is most times not caused by third-party software. If your MacBook Pro frequently crashes, it could be caused by any of the following:
• An OS installation that may be damaged
• A corrupted kernel cache
• A corrupted NVRAM (non-volatile memory)
• A faulty peripheral device
• An unknown bug in OS X
• Internal hardware fault
Dealing with these issues is as simple as taking them in turns to eliminate what is unlikely to be the cause.
If the constant crashes have become more like a nightmare, here are the ways to deal with the situation and get your MacBook back and running efficiently.
Start in Safe Mode to Deal with Corrupted Kernel Cache
To eliminate compromised kernel cache, start the computer in safe mode. Reboot in the normal way afterward to see if any changes are seen. Starting your computer in safe mode can resolve startup issues even if the computer fails to start. Do it as follows:
1. “Press down shift key after the power button is pressed”. Tap the power button and immediately press and hold down the shift key. The Apple icon should appear.
2. “Release Shift Key when login window comes up”. Watch to see when the login window shows up and release the shift key. For MacBooks that are encrypted with FileVault, you may be prompted to log in two times. The first is to unlock startup disk. The other is to log in to the Finder. Take a note if the issue doesn’t come up when the computer is started in safe mode.
3. “Restart your computer normally” To leave the safe mode, you should start Mac normally without pressing down the shift key. Observe if this causes any positive effect. If the issue doesn’t come up again, your kernel cache should be responsible and the safe mode has done the fixing for you.
Resolving a Corrupted NVRAM
You can check NVRAM issues in two ways:
If you have user-replaceable NVRAM installed and you’ve done an upgrade with a different one from the original, reinstall the original to see what happens. What you have installed must match the technical specifications.
MacBook Pro’s NVRAM can be reset to resolve crash issues as well. If your Mac has a question mark icon on startup or starts from a different disk from the selected one in Disk preferences, resetting NV RAM can help in some ways. Do it as follows:
4. “Turn on MacBook Pro and press down Command, Option, R, and P”. Tap the power button to put on the computer and hold down these four keys: P, R, command, and Option. Release the four keys after about 20 seconds by which the Apple logo might have appeared.
The NVRAM resetting process may affect some System Preferences' settings. You may need to adjust these settings. These include sound volume, startup disk selection, display resolution, and time zone.
If you use a Mac with firmware password ON, you will have to turn it off for the reset to take effect.
Reinstalling MacOS can Help Resolve Frequent Crash Issues
You can implement a reinstall from macOS Recovery. This installs versions, depending on your combination of keys when starting the reinstall.
5. “Turn on Mac and press down Command, Option and R keys” Do this using your keyboard. This key combination will install the latest version of MacOS compatible with your model. An Apple logo should appear.
6. “Release the keys” When the Apple logo or in some models a spinning globe appears, let go of the keys. The MacOS Utilities window should come up.
7. “Reinstall MacOS” Click Reinstall MacOS from the window. A new window shows up.
8. “Click continue” Click the continue button from the resulting window to reinstall MacOS. An onscreen instruction to choose your disk will be presented or else click show all disk.
9. “Install MacOS” Select a destination and click restore to start the installation process. The computer will restart automatically when the installation is complete.
This will positively make a change to your MacBook frequent crash issues.
