Sudo defaults delete /Library/Preferences/

This is what TeamViewer Support provided me with: defaults delete ~/Library/Preferences/ĭefaults delete ~/Library/Preferences/.plist These are terminal commands, meaning you need to launch the Terminal application (usually found under Applications > Utilities). NOTE: YOU NEED TO RUN THESE COMMANDS ON THE NEW (CLONED) MAC, NOT THE ORIGINAL MAC. (I would expect the process for a PC to be different so I’m not covering how to do this on the PC.) Here are the steps (which I slightly modified by adding some additional lines for the latest version 10 of TeamViewer) to reset the TeamViewer ID. How to Reset the TeamViewer ID After Clonging a Mac So, instead of having to search for the solution, I figured I would write out the easy steps to reset the TeamViewer ID. I had read some support posts and tested out some things (like changing the MAC address) to try to reset the TeamViewer ID but until I actually contacted TeamViewer support, none of the other fixes worked. Unfortunately, that means that on cloned Mac systems, the TeamViewer ID will be the same on the old and the new Macs, pretty much rendering TeamViewer useless when both cloned and original Macs are running. When TeamViewer sets up the TeamViewer ID, it makes it so that you cannot easily change it.

As I was going to reconfigure the old Mac for my daughter, I was also going to set up TeamViewer on that Mac. As part of the Migration Assistant process, TeamViewer was copied over to the new Mac so I didn’t need to reconfigure anything…or so I thought. So one of the first things that I do is to configure TeamViewer on any machine that I may need to provide remote assistance to. One of the applications that I actually use on her machine is TeamViewer which is fanstanstic if you need to provide remote assistance to a Mac or PC (you can actually set up a free account – I highly recommend this service). Recently, I set up a new MacBook Pro for my step-mom where I used Apple’s Migration Assistant to easily copy over all of her data, applications and preferences.
