Apple has introduced a security mechanism since macOS 10.14 (Mojave), which requires special access to be granted to remote control applications like TeamViewer. If you use macOS 10.14 or higher version, it is neccessary to enable the accessibility permissions for TeamViewer, otherwise the TeamViewer will not be installed, or any TeamViewer users connecting to macOS 10.14 or higher version will not get the ability to see or control anything on this mac.

How to Grant Access Permission
When launching TeamViewer for the first time on the Mac running MacOS 10.14 (Mojave) or higher version, you might be prompted with a Review System Access page.
You can also re-open this page by clicking Help =>Check System Access after loading TeamViewer.
By default, all permissions are set to Denied. To ensure a proper remote session, Screen Recording and Accessibility permission are required at minimum. You can follow the steps below to get the permission:
1. Click Request Access for Screen Recording and Accessibility.
2. You will be prompted the system Privacy page. Click the small + button as showing in the screen shot below. Next select TeamViewer, and click Open to add it to the list.
3. Check if TeamViewer is in the panel, if yes, put a check next to it to enable it.
Note: If the system does not allow you to do that, please click the Lock icon to make the changes available.
The yellow triangle icon in the upper-left area of the TeamViewer window is shown until you have allowed the system access for TeamViewer:
How to Do if You Cannot Get the Review System Access Page?
If you are using an older version of TeamViewer, or you previously clicked the Deny button on that page, you might not be able to get the Review System Access page when you launch TeamViewer. When this happens, you can grant the access from the steps below:
1. Go to System Preferences => Security & Privacy => Privacy
2. You will get the same page as explained above to add TeamViewer for Screen Recording and Accessibility permission. Please Navigate to Screen Recording and Accessibility and follow the steps above to add TeamViewer into the Allow list for each of them.
After all are properly done, you can restart the TeamViewer, and give our tech support your TeamViewer ID and password to start the remote assistance.

As of macOS High Sierra, Apple has introduced a new security measure. The system extensions for all newly-installed third-party software will automatically be blocked from running. If your MOTU interface is not showing up in Audio MIDI Setup, MOTU Audio Setup, the MOTU Discovery App, or your DAW on High Sierra or Mojave, you might need to allow the driver in your System Preferences.

This is enabled in System PreferencesDock using the Show recent applications checkbox. Automatically keep your Mac updated Apple has moved Software Updates to its own dedicated pane in System. Note: If the system does not allow you to do that, please click the Lock icon to make the changes available. The yellow triangle icon in the upper-left area of the TeamViewer window is shown until you have allowed the system access for TeamViewer. Launchpad doesn’t allow you to access the shortcut menu. Control-click the app icon, then choose Open from the shortcut menu. The app is saved as an exception to your security settings, and you can open it in the future by double-clicking it just as you can any registered app. Note: You can also grant an exception for a blocked. Look for Adobe Photoshop CS5 and the message “Allow the apps below to control your computer”. What to do when apps won’t open in Mojave If you are using old apps it is likely that you will.
To enable the MOTU drivers, follow these steps:
- Download and install the very latest installer for your MOTU interface.
- After restarting, open System Preferences.
- Select Security & Privacy.
- In the General section, click the Allow button.
Mohave System Preferences Allow Software
- The Allow button will disappear 30 minutes after installation. To display the Allow button, run the installer for the MOTU driver again.
- This behavior will only occur when installing a MOTU driver on Mojave for the first time. If you have installed the driver on an earlier version of macOS and then upgrade to 10.14, you should not need to enable the driver.
- This issue is not specific to MOTU. It is a general change introduced in High Sierra and will affect any third-party (i.e. non-Apple) kernel extensions.
