Starting in macOS Big Sur, you may notice some unusual popups when an app on your Mac receives an update. This happens when an install/update has occurred for an app that leverages kernel or system extensions. In order to use the app, you’ll need to approve the extension, authenticate with administrator credentials, and reboot your Mac.
Here are two example popups you may run into when this occurs:
When you see this notification - whether it comes from running an installer from the internet, updating an app via MacManage, or an update running in the background on your workstation - here are your next steps:
- Click Open System Preferences or Open Security Preferences in the popup. You could also manually navigate there via the Apple menu:
Click on Security & Privacy if you are not automatically brought to the above preference pane
- Click on the lock to allow changes - type in your administrative credentials. If you're not an administrator, please contact your IT support team, or temporarily promote your account.
- Look for the Allow button at the bottom-right and click it. You'll be asked to confirm if you'd like to proceed:
- Click Restart to update your system extension cache and reboot your Mac.
- Upon rebooting, head back to System Preferences and the Security & Privacy → General tab to confirm the message is gone. If not, repeat the process until the Allow button is no longer present (in our testing a few apps required this process to be done twice)
Apple will eventually be dropping support for kernel extensions, and a somewhat complex workflow needs to be executed to enable them on M1 Macs. Always make sure you know and trust the software you're using that requests the above be performed, as system and kernel extensions provide a deep amount of access to your computer.
