I get a message stating that system extensions are prevented by my security settings:
First off, congratulations on your speedy new Mac! Apple has revised the way third party extensions are managed for Macs using their new chips - they are in fact entirely disabled and cannot be allowed by default. The good news is that we have a solution:
Changing Security Policy for macOS to allow third party extensions:
- Turn off your Mac.
- Turn your Mac back on, but keep holding the power button past the startup chime and Apple logo until you see a boot option selection screen:
- Choose Options, click on 'Continue', and enter your password if prompted to do so.
- From the menu at the top of the screen, choose Utilities -> Startup Security Utility:
- After selecting your primary hard disk, click on the button labeled 'Security Policy...'
(If you have more than one copy of macOS installed, you may see more than one disk)
- Toggle the Reduced Security-mode and the Allow user management of kernel extensions from identified developers-options, then click 'OK'.
- Restart your Mac.
After following the steps above, you will be able to proceed as outlined in the article: How do I enable the required kernel extension for Microsoft NTFS for Mac by Tuxera?
