Audio Capture Engine, generally referred to as “ACE”, is Rogue Amoeba's powerful audio handling component. ACE captures audio on your system, so it can be used as you desire with these Rogue Amoeba's products:
On MacOS 11 (Big Sur) and MacOS 12 (Monterey), the initial installation of ACE requires some 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 Big Sur and Monterey. The same steps apply for all applications using ACE. 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 ACE has been blocked from running. Don't worry, that's expected! 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 Allow button to permit ACE to run on your Mac.
You're at the final step. Click Restart. When you log back in to your Mac, the application will be ready to go. Good work!
