CRITICAL – PLEASE READ BEFORE INSTALLING AND FOLLOW THESE DIRECTIONS

If you’re using an M1 Mac, you will need to allow user management of kernel extensions to install the Apogee driver.

1. Quit this installer and shutdown the Mac.
2. Press and hold the Mac’s Power button until the display shows Loading Startup Options, then release it. This takes you to the Startup Options screen.
3. In the Startup Options screen, select the Options icon, then click Continue underneath it.
4. Once the main window has loaded, select the Startup Security Utility in the Utilities menu. You’ll then be prompted to select the system for which you want to configure startup security. Once you’ve unlocked that disk, click on the button to set startup security for that disk. Then select Reduced Security, and check the upper of the two boxes, which allows user management of kernel extensions.
5. Quit Startup Security Utility, and select Restart from the Apple menu to restart into normal mode.
6. Once you’ve restarted, launch this installer again and begin the install. Towards the end of the install, before you restart the Mac, open System Preferences and go to the General tab of the Security & Privacy pane. If you see a message towards the bottom of the window with an Allow button, then unlock the Security & Privacy pane and click the Allow button. If the Apogee installer has finished, restart the Mac.

KNOWN ISSUES
• Some users may experience an issue after installing where the iLok License Manager app won’t open. This is usually accompanied by an ‘Activation Error – DirectIO’ dialog and/or a ‘Software Component Unavailable’ dialog. The solution is to run the latest iLok License Manager installer again after you run the Apogee installer. The iLok License Manager installer is available as a download from Pace’s iLok website. If the iLok License Manager opens fine after you run the Apogee installer, there is no need to run the iLok License Manager installer again.
