How to grant access to TeamViewer on your Mac
- If you're using the latest release of TeamViewer 14 on your Mac running macOS 10.14 (Mojave), you will be presented with this dialog when you start TeamViewer:
Note: if you're using an older version of TeamViewer, you won't see the dialog above. Instead, macOS will prompt you with the dialog below when the first incoming connection is made to your Mac.
- In the dialog shown above, click the Request Access button, which will bring you to this Accessibility Access (Events) dialog:
- Click the button Open System Preferences. You will be taken to the Accessibility section of the Privacy pane, inside the Security & Privacy preferences.
- Click the lock icon in the lower-left corner to make changes. You will be prompted to enter the credentials of an administrator account to continue.
- Put a check next to TeamViewer to grant it access:
- Now you can close the Security & Privacy window. The next time you want to receive an incoming connection with TeamViewer, the person connecting to your Mac will now be able to control it with their mouse and keyboard.
How to grant access when you aren’t presented with the dialog
If you're using an older version of TeamViewer, and you're not presented with the Accessibility Access dialog asking you to grant access to TeamViewer – or if you had previously clicked the Deny button on that dialog – it’s still possible to grant access to TeamViewer.
Additionally, in some cases, you can grant access to TeamViewer immediately after installing TeamViewer onto your Mac, before the first TeamViewer connection is made to your computer. Note that this is not possible with TeamViewer Host.
- Go to System Preferences, then Security & Privacy, then Privacy, then Accessibility.
- Click the lock icon to make changes.
- If TeamViewer is already shown in the pane, then put a check next to it to enable it.
- If not, click the small button with the plus symbol underneath the pane. This opens a Finder window:
- Navigate to your Applications folder, select TeamViewer, and click Open.
- Now you should have TeamViewer listed in the pane and enabled.
How to grant access when starting TeamViewer with System
If you enable the setting Start TeamViewer with System, which is found in TeamViewer’s Preferences, then TeamViewer will restart using a different process called TeamViewer_Desktop.
This is also the case when using TeamViewer Host.
The first time a connection is made to your Mac after doing this, you will be presented with the Accessibility Access dialog once more, but this time referring to the new process. You will need to grant access once again by clicking the button “Open System Preferences” and following the same steps outlined above.
Unfortunately, it is not possible to grant access to the TeamViewer_Desktop process manually. You will need to wait until the first incoming connection is made to your Mac before you can add this process.
