1158 How Do I install a driver on M1 Mac?Aug-17-21
Apple M1 Macs come with increased security which prevents users by default from installing non-Apple drivers (kernel extensions). To install the Sonnet Twin 10G driver (or any other 3rd party driver) you must follow these steps before you run the installer:

1. Shut down your Apple M1 Mac
2. Hold the power button to switch the computer on in Recovery mode (keep the button pressed until the Startup Options dialogue appears on the screen)
3. From "Utilities" menu, select "Startup Security Utility".
4. Select your boot drive (generally named "Macintosh HD").
5. Go to the "Security Policy" section, click "Reduced Security" and then "Allow user management of kernel extensions from identified developers"
6. From Apple logo menu select "Restart" to restart your computer.
7. Run the Sonnet Twin10G Driver installer.
8. Midway through the installer, you should see a prompt to "Allow" the extension to load. To allow:
- Open System Preferences,
- Select Security & Privacy preferences
- Unlock and enter password
- Select allow installation
- Close Window
9. Once installation is complete, restart your computer to complete the process.

More information about the security settings on Apple Silicon systems can be found in this Apple article.
