How to change startup disk security settings on an Apple silicon Mac

 

Some Seagate and LaCie software use a kernel extension (kext). Apple silicon Macs require that users change the security settings to ‘Reduced Security’ for the software to function properly.

To change the level of security on your startup disk:

  1. Shut down the Mac
  2. Press and hold the power button until you see “Loading startup options”
  3. Click Options
  4. Click Continue
    • If asked, select a user > Click Next > Enter password for admin account
  5. In the menu bar at the top, Select Utilities > Startup Security Utility
  6. Select the startup disk
    • If the disk is encrypted, Click Unlock > Enter Password > Click Unlock
  7. Click Security Policy
  8. Select Reduced Security
  9. Put a check next to “Allow user management of kernel extensions from identified developers”
  10. Click OK
  11. Enter admin password > click OK
  12. Once changes are applied, click the Apple icon and Restart
