The caveat with setting a firmware password is that someone in Desktop Support helping a remote user may have to provide this password to the end user. Since this is at the hardware level, no one without the password can install or upgrade. Setting a firmware password prevents anyone without the password from booting to the Recovery HD, erasing the existing operating system and installing a new macOS. Removing admin privileges, though, makes your end users heavily rely on IT administration. The most basic step we can take is to remove admin privileges for end users and require they use Self Service for running policies you allow. It will prevent any macOS installer from running when double-clicked including Catalina, Mojave, High Sierra, etc.Īnyone with admin privileges on a Mac can do practically anything, including installing an operating system.

Be sure to specify the penalty for non-compliance. The easiest method for restricting unwanted installations is to disclose your organization’s policy to end users that states “Do not install major macOS upgrades unless authorized by the Information Technology Department”.
That usually means taking more than just one step.įollowing are some ideas from less restrictive to more intrusive. What steps can we take to prevent our end users from installing a new major macOS version? Keep in mind, end users can acquire the installer and run the installer in multiple ways.
