Macbook crashes after HighSierra install

I've been trying to upgrade to High Sierra however, every time it restarts my computer after finishing the install my computer crashes. My computer will then restart saying there was an error and applications didn't shut down properly. Also, a message about the crash is sent to Apple.

I really want to upgrade so that I can use iTunes on my new iPhone 8.

Any help is greatly appreciated!

Thank you,

Scott
