How To Fix Dead MacBook Issue and Recover from Dead MacBook
For MacBook users, when your MacBook is working properly, you don’t think it may suddenly corrupt. This is the trust that accidents can be happen at any time. So when the MacBook suddenly crashes or corrupts, and we cannot enter into it, how do we fix it? Today, this post will give you the suggestions about this problem.
First, you need to make sure that the files have been backed up, or when the MacBook suddenly crashes, that the files on the MacBook have not been fully backed up. Then, I will give you three methods to fix the dead MacBook issue.
How to Fix the Dead MacBook Issue
Solution 1: Clear Parameters & Files
Step 1: Users need to reset PMU (Power Management Unit). Please follow the detailed steps: shutdown MacBook — press and hold “shift”, “control”, “option” and “Power” at the same time. And restart the MacBook.
Step 2: Users need to reset PRAM (Parameter Random Access Memory). Please follow the detailed steps: shutdown the MacBook — before the gray screen is displayed, press and hold “Command”, “Options” “P”, “R” and “Power” until the MacBook restarts again.
Step 3: Users need to delete Kernel Extension Caches. When the MacBook reboots, please press the “shift” button to enter safe mode. Next, open the terminal and use two commands to delete files with root privileges (mainly used by drivers and some extension modules) – su rm /System/Library/Extensions.kextcache &
su rm /System/Library/Extensions.mkext
Then close your MacBook immediately.
Step 4: Restart your computer and please be patient, as the reboot process will become very slow after deleting the cache.
Solution 2: Use Disk Utility
- Follow the solution 1 to reset PRAM & PMU.
- Then restart your MacBook, adjust the screen resolution, and then shut down the MacBook.
- Please launch your MacBook using the installation CD.
- Go to Disk Utility and execute Repair Permissions/Repair Disk.
Solution 3: Restore System
If the two methods cannot help you to fix the dead MacBook, you have to restore the system. But it is very dangerous because it may hurt the files on the MacBook. Therefore, before your restoration, you can recover the files to another place. Apple offers a special tool to transfer data from a crashed MacBook Pro to another MacBook Pro. If you have two MacBooks, you can use a USB-C adapter to connect the logic board of dead MacBook to another MacBook. However, in most cases, we only have one MacBook. Therefore, we have to recover the files from the dead MacBook before we make the restoration.
Recover from the Dead MacBook
How to recover the files from the dead MacBook already becomes a crucial problem for Mac users. Here, we can search the Internet for data recovery on the Mac. Please choose the one that you think is the most appropriate. Here I downloaded MiniTool Mac Data Recovery Bootable edition as an example (download link: https://www.minitool.com/data-recovery-software/mac-data-recovery-boot-disk.html ). Please follow the detailed steps:
First, when you install this program, please burn this software to a USB/CD to make a bootable disk.
Second, insert the bootable disk into the dead MacBook.
Third, launch the MacBook and change the boot settings so that it can boot from the USB/CD.
Fourth, under the guidance, start the hard drive on the dead MacBook. You can see the interface of Mac Data Recovery as the picture below.
Fifth, select the Damaged Partition Recovery to scan the dead MacBook hard drive. Then you can see your files on the results after the scanning. Select them and click Save to another external hard drive. Now your files on the dead MacBook are transferred to the safe hard drive.
At this time, you can restore the system of the MacBook.
In the end, the dead MacBook is a big question for users. Therefore, it’s very important to discuss the solutions to the problem of dead MacBook. Users can clear parameters or files and use Disk Utility to fix dead MacBook issue. For other users who don’t have a backup file from a dead MacBook, they need to recover the files from dead MacBook first, and then they can restore the system on the MacBook.
