Verbose Mode is dropped on macOS Sierra? Hi guys,

Anyone know if Apple removed Verbose Mode in macOS Sierra or not? When It seems Verbose Mode couldn't be accessed any more.

One more thing, it also doesn't work with booting into Single-user Mode, Safe Mode or Verbose Mode via command line.

Any reply would be appreciated. Thanks.

Best Regards,
Vincent
System Integrity Protection (SIP) disables changes to NVRAM. In order to make changes, you need to temporarily disable SIP by doing the following:


Boot into Recovery Mode. (Hold Command-R from the time you start your machine until the Apple logo appears.)
Open the Terminal from the Utilities menu.
Enter the command:

csrutil disable

Reboot and you will be able to run your desired commands from within a normal session.
It's strongly recommended that you re-enable SIP when you're done making adjustments. To do so, run this command:

csrutil enable



Note that if you intend to make a lot of changes to NVRAM, you can leave SIP enabled but disable NVRAM protection by running the following command from the Recovery Mode Terminal:

csrutil enable --without nvram


Again, you will need to reboot for changes to be effective.
