Problem with "csrutil enable --without debug" on Sierra
You need to partially disable System Integrity Protection. I do not encourage you to disable System Integrity Protection. It makes your computer less safe.

How to partially disable System Integrity Protection


Boot to Recovery OS by restarting your machine and holding down the cmd and r keys at startup
Launch Terminal from the Utilities menu
Enter the following command: csrutil enable --without debug
Reboot your computer
