Be sure to specify the penalty for non-compliance.This does absolutely nothing to prevent someone from doing it anyway, but it asserts authority without removing any privileges. That usually means taking more than just one step.Following are some ideas from less restrictive to more intrusive.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”. Be sure each Mac has a unique password that won’t unlock any other computer.Administrators need to balance limiting access to the Big Sur installer with needing to install it themselves. Since this is at the hardware level, no one without the password can install or upgrade.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. 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.Removing admin privileges, though, makes your end users heavily rely on IT administration.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. It will prevent any macOS installer from running when double-clicked including Catalina, Mojave, High Sierra, etc.Anyone with admin privileges on a Mac can do practically anything, including installing an operating system.

It’s not a full installer but rather the same app without the 12 GB SharedSupport.dmg in the app bundle. This will download what some folks describe as a “stub” installer.

Get anime studio for free on macBefore we can deploy it to our fleet, though, we need to package it.Jamf’s Composer application can do this, but because of the size of the Big Sur installer (it’s just over 12 GB), Composer can only create a DMG file it cannot create a PKG file. This downloads the latest version and places it into the Applications folder. When using it with home users or those who’ll be invoking the installer themselves using something like Self Service, be sure to alert them not to put their Macs to sleep, to leave them plugged in to power and to allow time for the installation to complete.Another way to acquire the installer is through the App Store on a Mac. ![]() It also has the advantage of working even if we’ve used Software Restrictions to block the InstallAssistant process and we can invoke it as part of a script or a Jamf Pro policy (optionally, using Self Service).To find the command line tool, right-click or Control-click the Install macOS Big Sur application and choose Show Package Contents > Contents > Resources.
