And macOS 10.15 (Catalina) has strengthened the security and privacy even further and requires additional permissions to be given to TeamViewer in order to control your Mac. Without this access, TeamViewer users connecting to macOS 10.14 or higher will only be able to view the screen but not control it with their mouse or keyboard.
To complete this, you will need to have a local administrator account on each machine, and you need to know the credentials.
6 Steps total
Step 1: Fire up Teamviewer
For this example, I used Teamviewer 8
Step 2: Ask for the ID number for the user, connect to that ID.
This will be a 9 digit number
Step 3: Local admin already?
If the user is not local admin already (if they are you will be able to interact with UAC), you will be prompted with this screen
Step 4: Click on 'Click for additional information'
You will be prompted with the next window
Step 5: Authenticate as the local admin account
This basically allows you to restart the clients Teamviewer session with the local administrator account
Step 6: Connect & interact with UAC on a standard account!
Once you enter correct credentials, the status in the bottom left will tell you that it is restarting, and then you will join the end user's session, as always
You are now able to interact with end-user UAC pop ups remotely.
