Disabling tailspind and spindump on macOS High Sierra
macOS High Sierra2 includes System Integrity Protection, which means that certain files are untouchable and uneditable. This has the benefit of helping keep your system files pure and malware-free, with the cost of flexibility.

To disable tailspind and spindump means temporarily disabling System Integrity Protection (SIP). To disable SIP:

Boot your Mac into Recovery Mode by restarting with Command-R held down until the Apple logo appears.
Once your Mac is in Recovery Mode, go to Utilities > Terminal.
In the Recovery Mode Terminal, issue csrutil disable and press return.
Reboot your Mac.
Once SIP is disabled, the steps to disable tailspind and spindump are pretty straightforward
