A native Apple Silicon build has been confirmed running on Macs in the Rosetta Check community.
AI Recommendation
1 suggestionEleven MKII is a Pro Tools AAX plugin, not a standalone app, so it is updated through Pro Tools' own plugin management rather than as a separate download. To get the native Apple Silicon build: first ensure your Pro Tools installation is on version 2023.6 or newer, as that is when Avid added native Apple Silicon support to Pro Tools and its included plugins. You can check your Pro Tools version in Pro Tools → About Pro Tools once the app is open. If you are on an older version, use Avid Application Manager (the official Avid installer tool) to upgrade Pro Tools itself to the latest version — the native Eleven MKII plugin will come along automatically as part of that update. After upgrading, Pro Tools will load the native build of Eleven MKII by default and you should see noticeably better performance and lower CPU usage during mixing sessions compared to running the Intel version under Rosetta.
