Retrieve Data from MacBook Air That Fails to Start After Update

“On my Macbook Air running with El Capitan, I downloaded and installed some updates (iTunes, iBook, and more updates of about 100MB) and restarted the machine for updates to take effect. But the Mac never started again. I am worried now and not able to find what the problem is. I tried all combinations of keys to reset but I got no result; as it is not booting. I have stored almost all my vital office files and folders on my Macbook, so can someone please help me to solve the issue?”

You can follow below troubleshooting to make your Macbook boot normally:

• Hold power button until your MacBook turns off completely and then release it. Press the power button after few minutes to turn it on.

• Reset NVRAM: Shut down Mac and turn it on > press and hold Command-Option-P-R keys when you hear start up sound > system will restart > when you hear second startup sound leave the keys
• Open Terminal in /Applications/Utilities > type system_profiler SPExtensionsDataType > ~/Desktop/kextList.txt and strike on return > open kextList.txt file created on desktop and simultaneously press “Apple (Command)” and “F” keys > in find field, type Obtained from: Not Signed > Copy destination to .kext file > Click next > go to /System/Library/Extensions and get rid of unsigned kext files > Reboot
