Macbook permanently crashes while updating to El Capitan
I did it with simply press Cmd + R, and then press off. Cmd + R I kept pressed until Apple logo appeared, then I get into Install OS X mode. There you should once again connect to the internet, choose language,and waiting for new install.
Yes - this is generally an easy recovery - the next step is to get a backup (which will be a pain if you don't have one) and then perform an erase install.

That part should go easily. If that fails, you likely have a hardware error that would need to be addressed. Also, if you haven't tried disconnecting everything from the MacBook that you can except power. No USB, no ethernet, no thunderbolt, no SD cards, etc...
Had the same problem with my MacBook Air 11" 2013 model. None of the provided solutions worked for me. I also tried to reinstall El Capitan by booting into recovery mode. I reinstalled it two times but the error kept showing up.
So here's how I solved the problem:
- Shut down your mac.
- Boot into safe mode (Hold shift while booting up). Hint: During the screen with the Apple logo and the progress bar, nothing will look different, but at the login window, there should be "SAFE BOOT" on the top right corner of the screen to confirm that you are in safe mode
Log in again. This time it should work, if it doesn't go to step 1 again.
Finish up the installation process.
- Backed my data up
- Fresh reinstall
