The focus of this article is to resolve kernel panic and recover inaccessible data on Mac with Stellar Data Recovery application.

But What is a Kernel Panic Error?

A kernel panic is a safety measure imposed by the macOS kernel when it encounters a fatal error that can lead to major data loss. It also safeguards macOS file system & hardware from possible damages. This panic may be caused due to many reasons, most of which arise from third-party applications, a failing storage drive, troublesome logic-board, and application errors. Luckily, in most cases, a kernel panic error can be resolved by merely rebooting the Mac. While other scenarios that prevent the OS from booting optimally may require an expert's diagnosis and repair.

Resolve White Screen of Death

This error is usually identified after updating the system when the MacBook or iMac starts up but halts with a white screen. There are several ways you can resolve this issue; some of the methods are mentioned below:

  1. Reboot into Safe Mode: Rebooting the Mac into safe mode can resolve most of the minor problems. If the computer runs properly in safe mode, try running it normally. It’s most likely your Mac will function smoothly.
  2. Reset the NVRAM and SMC: The process is explained in detail in Top 10 Mac Problems and Their Solutions

Resolve Grey Screen of Death

Similar to the White Screen of Death, the Grey Screen of Death is most likely to appear after an operating system update. Follow the below steps to resolve the problem of Grey Screen of Death in MacBook and iMac:

  1. Boot into Safe Mode: This is a feature in OS X and macOS that allows you to troubleshoot the Mac. Once you are in safe mode, the first thing you should do is clear the cache on the Mac and then remove any recently installed applications. By utilizing safe boot, you can also check the probable file system errors. If the errors are detected, the repair is performed automatically. Restart the Mac, and hopefully the problem is resolved. If not, then follow the subsequent solutions.

  5. Release the keys after Apple logo appears
  6. Click Disk Utility and continue
  7. Choose the disk to repair
  8. Click First Aid button.
  9. Reinstall macOS: If all the approaches fail, you can reinstall the macOS using a new feature available in macOS called Reinstall macOS. Don’t worry, this won’t change your files and folders (unless you do not erase your startup disk); it will install a fresh copy of macOS. Reinstalling macOS is the most decisive answer to all your OS problems.

Resolve iMac Restart Loop

Resetting NVRAM, booting the iMac in safe mode, or using Disk Utility to repair disk are the most common methods that can help resolve restart loop in your macOS. Additionally, you can try disconnecting all peripheral devices and restarting the MacBook or iMac.

You are in luck if you have a Time Machine backup as you can use it to erase the macOS and reinstall a working copy of the OS.
