To help whitelist all kernel extensions from a particular vendor or whitelist only specific ones, Apple has made two sets of identifying criteria available:Ī team identifier is a alphanumeric string which appears similar to the one shown below: For more details, please see below the jump. To help companies, schools and institutions, Apple has made a management profile option available to centrally approve third-party kernel extensions. This process is relatively easy for an individual to manage on their own computer, but it would be very difficult to manage when dealing with more than a handful of Macs. Once approved, another copy of the kernel extension is made and allowed to load. ![]() While waiting for the kernel extension to be approved, a copy of the kernel extension is made by the operating system and stored in the following location: Another attempt is made to load the kernel extension. After that, it disappears until the following happens: Note: This approval is only available for 30 minutes. Go to the Security & Privacy preference pane The alert tells the user how to approve the loading of the kernel extension signed by a particular developer or vendor, by following this procedure:ī. When a request is made to the OS to load a third-party kernel extension which the user has not yet approved, the load request is denied and macOS presents an alert to the user.Ģ. Without the profile, third-party kernel extensions will need to be approved through the User-Approved Kernel Extension Loading (UAKEL) process. This profile allows a company, school or institution to avoid the need to have individual users approve the running of approved software. UAMDM grants mobile device management (MDM) additional management privileges, beyond what is allowed for macOS MDM enrollments which have not been “user approved”.Īs of macOS 10.13.4, the only additional management privilege associated with UAMDM is that it allows you to deploy a profile which provides a whitelist for third-party kernel extensions. As part of macOS 10.13.2, Apple introduced the concept of User Approved MDM Enrollment (UAMDM).
