If you'd like to view the Available Updates on a single machine, simply navigate over to the Available Updates tab in GoLive.
By using softwareupdate -l you can check the available System Updates on the Terminal of your macOS device. This is what GoLive uses to collect the information that it displays under Available Updates.
Once you navigate over to the Available Updates tab, you'll have the option of deploying an update to the machine or ignoring it.
GoLive acts like each device's individual policy when it comes to Restart Settings because it does not respect the settings you set up on the policy. You can see when the Update finishes from the Events tab in GoLive. Once the update is done you have several ways to restart the device.
Note: This simple script prompts the user to let them know their device has been updated and then proceeds to prompt the user to restart.
#!/bin/bash osascript -e 'display dialog "Hello, your device has been updated! Please restart as soon as possible"' osascript -e 'tell app "loginwindow" to «event aevtrrst»'
