Detecting a Touchbar Mac


Today’s task, figure out if the machine has a touch bar or not. While there’s a few files that contains info about the touch bar: “~/Library/Preferences/com.apple.controlstrip.plist” “~/Library/Preferences/com.apple.touchbar.agent.plist” These are user files.

Casper Replication


One of the problems we have in our environment, is our smaller offices don’t necessarily have a tunnel set back to HQ, and they have a lower bandwidth available so we wanted a DP onsite. Originally we were doing replication via JDS. We still ended up using JAMF’S create DP script to provide us the failover we require. This worked however it…
