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.
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.
