I'm on macOS Sierra 10.12.5, and trying to add a library to the
usr/lib folder (for an OpenFrameworks project I'm working on).
However, none of the suggested answers seem to have any effect. On Sierra, it seems that when rebooting in recovery mode, there is no longer any way to access a Terminal window (unless I'm mistaken), so System Integrity Protection can't be disabled by running
Does anyone have any suggestions?
