Unsupported

Kernel extensions that use previously deprecated and unsupported KPIs no longer load by default. You can use MDM to modify default policies to not show dialogs periodically and to allow the kernel extensions to load. For Mac computers with Apple silicon, you must first change the security policy.

To install a new or updated kernel extension in macOS Big Sur, you can do either one of the following:

  • Instruct the user to follow the prompts within Security & Privacy preferences to allow the extension, then restart their Mac. You can permit users who are not administrators to allow the extension using the AllowNonAdminUserApprovals key in the Kernel Extension Policy MDM payload.
  • Send the RestartDevice MDM command and set the RebuildKernelCachekey to True.

Any time the set of approved kernel extensions changes, either after initial approval or if the version is updated, a restart is required.

Additional requirements for Mac computers with Apple silicon

Mac computers with Apple silicon require kernel extensions to be compiled with an arm64e slice.

  • If you have devices enrolled in MDM with Automated Device Enrollment, you can automatically authorize remote management of kernel extensions and change the security policy.
  • If you have devices enrolled into MDM with Device Enrollment, a local administrator can change the security policy manually in macOS Recovery and authorize remote management of kernel extensions and software updates. Additionally, an MDM administrator can advise the local administrator to make this change by setting PromptUserToAllowBootstrapTokenForAuthentication in MDMOptions or by setting the same key in the MDM profile.
  • If you have non-MDM devices or devices enrolled into MDM with User Enrollment, a local administrator can change the security policy manually in macOS Recovery and authorize user management of kernel extensions and software updates.
