This is a reference to the article “Mac stuck on Gray Screen with apple logo during boot after installing macOS Sierra“. These are the terminal command that I used in recovery mode when my Mac was unable to boot due to low disk space. I though of publishing the whole terminal commands output to those who have never used terminal or recovery mode to free up space on startup disk in case of no boot situation caused by low disk space or by some incompatible kernel extensions(.kext). This can be very helpful reference if your computer does’t boot normally and the safe mode does not work either. So the only option left for you is to use terminal in recovery to perform data backup and other troubleshooting. You can even copy data from internal hard drive ( user’s home folder ) to an external USB drive to save them.

If you see any other kext or driver apart from the above in your Mac then it must be a third party extension that you can safely remove or move to other location in order to prevent ir from loading at startup which may cause your Mac to stuck at grey screen with a loading bar.
These were the sample of Mac terminal command in recovery mode, which can be helpful or can be a great reference if you’re also troubleshooting your Mac and unable to boot normally.
