![]() ![]() It will be used to create an extension attribute, from which a smart computer group can be built as a target to scope our workflow to. This script will check that there is sufficient space and memory and that the computer meets the minimum requirements for macOS Big Sur. It’s a good idea to ensure that we only deploy the installer to eligible computers. Composer only supports building PKGs that contain files no larger than 8GB as such, we will have to build as a DMG.Īlternatively, we could use which will fetch the installer app for us and build a package all in one. The macOS Big Sur installer is pretty big this time around at 12GB. verbose Enable verbose output -help Print this help Use with -background to trigger a background scan regardless of "Automatically check" pref -agree-to-license Agree to the software license agreement without user interaction. ![]() all Include all processes in history (including App installs) ** Options: -no-scan Do not scan when listing or installing updates (use available updates previously scanned) -product-types Limit a scan to a particular product type only - ignoring all others Ex: -product-types macOS || -product-types macOS,Safari -products A comma-separated (no spaces) list of product keys to operate on. By default, only displays updates installed by softwareupdate. Ex: -full-installer-version 10.15 -install-rosetta Install Rosetta 2 -background Trigger a background scan and update operation ** Other Tools: -dump-state Log the internal state of the SU daemon to /var/log/install.log -evaluate-products Evaluate a list of product keys specified by the -products option -history Show the install history. r | -recommended Only recommended updates -list-full-installers List the available macOS Installers -fetch-full-installer Install the latest recommended macOS Installer -full-installer-version The version of macOS to install. specific updates -a | -all All appropriate updates -R | -restart Automatically restart (or shut down) if required to complete installation. usr/sbin/softwareupdate help usage: softwareupdate ** Manage Updates: -l | -list List all appropriate update labels (options: -no-scan, -product-types) -d | -download Download Only -i | -install Install. Take particular note of the -full-installer-version command, which allows us to specify which version we wish to download. If you’d like to learn more, you can view the softwareupdate help page by running the ‘ /usr/sbin/softwareupdate help’ command. This gives us a lot of good information to start with, so let's start building our command out: ‘/Applications/Install macOS Big Sur.app/Contents/Resources/startosinstall’ -agreetolicense -nointeraction -forcequitapps stdinpass: collect a password from stdin without interaction. passprompt: collect a password for authorization with an interactive prompt. user: an admin user to authorize installation. This is the default if no users are logged in. forcequitapps: on restart applications are forcefully quit. preservecontainer: preserves other volumes in your APFS container when using -eraseinstall. ![]() newvolumename: the name of the volume to be created with -eraseinstall. ![]() Optionally specify the name of the new volume with -newvolumename. eraseinstall: (Requires APFS) Erase all volumes and install to a new one. installpackage: the path of a package (built with productbuild(1)) to install after the OS installation is complete this option can be specified multiple times. To bypass "rebootdelay" send SIGUSR1 back to startosinstall. pidtosignal: Specify a PID to which to send SIGUSR1 upon completion of the prepare phase. This delay is in seconds and has a maximum of 300 (5 minutes). rebootdelay: how long to delay the reboot at the end of preparing. agreetolicense: agree to the license you printed with -license. startosinstall -usage Arguments -license: prints the user license agreement only. In this article, we’ll review the tools we need to use to build our workflow, link you to some existing scripts and perhaps inspire you to build your own! To start, let’s look at the documentation around the startosinstall binary. Great!Īs of macOS Sierra, Apple began enforcing the use of the startosinstall binary included in the installer application when triggering an automatic upgrade. Now it’s time to finally roll out the latest version of macOS to your end-users. So you’ve spent the last few months testing and verifying that all your applications will work with macOS Big Sur. ![]()
