Sibelius

Avid released native Apple Silicon support for Sibelius in version 2024.6 (June 2024). The native build offers significant performance improvements—up to 30% faster startup and up to 50% faster performance on large score interactions compared to the Rosetta 2 version. The latest Sibelius installers ship as a Universal Binary, so when you download and install from Avid, you automatically receive the native Apple Silicon build on M-series Macs. Visit your Avid account or Avid Link to download the latest installer, or launch Sibelius and check Help → Check for Updates to download the latest version. After updating, verify you are running the native build by opening Activity Monitor, switching to the CPU tab, and checking that Sibelius shows Kind as "Apple" rather than "Intel". If you use third-party audio plugins in Sibelius playback, ensure they have also been updated to run natively on Apple Silicon—outdated plugins will not appear in Sibelius's Playback Preferences and may cause playback issues. If a specific plugin has not yet been updated, you can still run Sibelius under Rosetta 2 temporarily by right-clicking the Sibelius app in Applications, selecting Get Info, and checking "Open using Rosetta" (though you will lose the performance gains).
