Our Audio Capture Engine, which we refer to as “ACE”, is a powerful audio handling component which enables audio capture with Airfoil for Mac on your Mac. ACE also provides audio capture abilities to several other Rogue Amoeba products, as well as many third-party licensee products.
Since MacOS 11 (Big Sur), the initial installation of ACE has required a bit of quick setup. The built-in ACE installer found in our products walks you through this.
On this page, we detail the full, step-by-step sequence needed to install ACE on MacOS 11 and MacOS 12. This is a one-time process, and you'll be up and running in just a few minutes.
When you first launch the application, it will direct you to install ACE. Click the Install button to proceed.
Enter your Administrator password (generally, the password used to log in to your Mac), then click OK.
You'll now see a message from the system, stating that your system currently does not allow system extensions.
Click the Open Security Preferences button to proceed.
If you clicked Open Security Preferences in the previous dialog, you'll already be in the right place.
If not, select System Preferences from the Apple () menu in the upper left. Click Security & Privacy, then the General tab.
Click the lock in the lower left corner, then enter your Administrator password. The Security & Privacy system preference will then be unlocked, and you'll be able to make changes.
Click the Enable system extensions… button to proceed.
This dialog explains how to access the Mac's “Recovery” environment. Click Shutdown.
To boot to the Mac's “Recovery” environment, press and hold the Touch ID or power button on your Mac.
When the screen says “Loading startup options…”, you can let go.
Select a user with administrator privileges, then click Next.
You'll be prompted for your login password. Enter it, then click Continue.
The Startup Security Utility should now load automatically. If not, access it from the Utilities menu.
Click your main system drive, then click the Security Policy… button. You can now adjust the security policy so ACE can run.
By default, you'll see the configuration is pictured above. Switch to Reduced Security and enable the first checkbox, “Allow user management of kernel extensions from identified developers”.
Your settings should now match the image above. You can now click the OK button.
Enter your password, then click the OK button. The new security policy will then be applied. When it's finished, the window will close.
Phew! You can now click the Apple () menu in the upper left. Select Restart, then log back into your account as normal.
You'll now see a message from the system, stating that ACE has been blocked from running. Don't worry, that's expected! Click the Open Security Preferences button to proceed.
