When installing software for your Apogee product, you may get an alert message that a System Extension was blocked.

  • Note: Even if this message does not appear, you still need to manually follow the directions below

This is a new security feature Apple introduced in macOS 10.13 High Sierra that requires a user’s approval before loading third-party kernel extensions. It applies to all future versions of mac OS including 10.14 Mojave, 10.15 Catalina, and above.

Click OK to proceed, then go to your Mac System Preferences > Security & Privacy panel to Allow the System Extension so your Apogee product will work properly.

If you do not see this Allow button, it is programmed to disappear after 30 minutes. To get it to reappear, uninstall your Apogee software (requires you restart the computer), then reinstall. At the end of the reinstall but before restarting your computer for the 2nd time, check Security & Privacy for this Allow button will reappear.

Advanced Troubleshooting:

If the Allow button does not appear even after a full uninstall and re-install of the software, here are some advanced troubleshooting techniques to find out where things are getting stuck:
System Information.app is a utility built into every mac that lets you see detailed information about your system. It is located in your Mac’s Applications > Utilities folder

Apogee driver appears in Disabled Software section

If the Allow button won’t appear in the System Preferences > Security & Privacy panel, check your System Information.app’s Disabled Software. If it is listed, then it is not being allowed. In this case, we must force the computer to load this kernal extension. Here’s how:

  • Find the Bundle ID of the kext listed in the Disabled Software section (In the example image shown, it is com.Apogee.driver.EnsembleFWOverideDriver)
  • Open Terminal.app also located in your Mac’s Utilities folder
  • Enter the following command:

sudo kextload -b {the kext bundle id}

In the case of the image given where the disabled software is for an Ensemble Firewire, the command is:

sudo kextload -b com.Apogee.driver.EnsembleFWOverideDriver

If this is a Duet USB, the command would look like:

sudo kextload -b com.apogeedigital.kext.ApogeeUSBDuetAudio

And last example: if this is an Ensemble Thunderbolt or Element Thunderbolt device, the command would look like:

sudo kextload -b com.apogeedigital.kextElementEnsemble

  • Type in your Mac’s password, then press RETURN
  • Wait two minutes
  • Open Mac System Preferences > Security & Privacy panel and see if the ALLOW button is now there (if it was already open, you must close it then re-open for the button to appear).
  • In some cases, you will need to restart your computer before checking for the Allow button in Security & Privacy.

If you continue to have problems after trying these steps, please contact Apogee’s Support Department here: https://apogeedigital.com/support/apogee-technical-support-form

NOTE: If you have an Element or Ensemble Thunderbolt and are running OS X 10.14.5 Mojave, the Beta version of the Apogee Control software is not compatible. Please wait for another Beta release or the full non-beta release to get around this issue.
