Why does NTFS for Mac need to be granted permission?
In the age of the internet and malware, security is paramount. Since the release of macOS 10.13 (High Sierra), third party kernel extensions are prohibited from loading without express permission from the user.
How can I approve the kernel extension required by NTFS for Mac?
During installation you will be notified if our kernel extension is blocked by macOS security and directed to bypass the restriction from within System Settings.
The notice about our blocked extension will appear in the Privacy & Security-section, under the Security-heading:
Once you've clicked on the button labeled 'Allow', you will have to restart your computer.
If you don't see the above, you may instead be shown a disclaimer that system extensions are disabled. In this case, please see How do I enable third party kernel extensions on Apple silicon-based Macs before you return to System Settings.
