This article will cover how to set the permissions for TeamViewer to work on Mac. Recent macOS versions require your permission for apps to provide remote control functionality. Without this permission, TeamViewer will not be able to work.
Adding Permissions for First Time
Go to automanager.com.
Click the green Remote Support button in the top right.
This will download a file called AMSupport.zip.
Open AMSupport.zip, and it will create an app called TeamViewer QuickSupport.
Open TeamViewer QuickSupport, and in the popup click Open.
In the agreement popup, click the checkbox, then click Continue.
A window will open asking for permissions to be enabled. Click Request Access…
Then click Open System Preferences.
In the window on the right, click the checkbox next to TeamViewer QuickSupport
On the left, find and click Accessibility, then click the lock in the bottom left and enter your password.
Check the box next to TeamViewer QuickSupport.
On the left click Full Disk Access, then click the “+” and select TeamViewer QuickSupport in the downloads folder.
Click Quit Now. Then reopen the app from the Downloads folder.
To check if the permissions were enabled, click Help > Check system access.
A window will open and show if all the permissions were enabled.
Updating / Editing Permissions
When starting TeamViewer on your Mac running for the first time, you may be easy to miss the dialog box below:
If you miss this dialog box, TeamViewer won’t work properly for you. You can also open this dialog by clicking on Help then click Check system access.
In order to remote control a Mac, you will need to give permission for Screen Recording, Accessibility, and Full Disk Access
To allow access, click the buttons in the dialog.
For example, to allow Accessibility, click the Request Access… button.
In the next dialog, click Open System Preferences.
This will take you to the Accessibility section of the Security & Privacy preferences:
You may need to click the padlock icon in the lower-left corner to make changes.
You might be prompted to enter the credentials of an administrator account to continue.
Check the box next to TeamViewer to grant access:
Note: If you are seeing the entry TeamViewer_Desktop in your list, make sure to check this box as well.
Go back to TeamViewer and repeat the same process for the other permissions.
When you are done, you may click the padlock in the lower-left corner again to prevent further changes.
The next time you want to receive an incoming connection with TeamViewer, the person connecting to your Mac will be able to see and control your device.
The permission status can be reviewed under Help -> Check system access at any time
