Some customers may encounter problems using iLok-protected plugins in the AudioUnit (AU) format when running macOS 14.4 Sonoma.
This issue affects DAWs that rely on Apple’s AU plugin format, including Logic Pro, GarageBand, MainStage, and Final Cut Pro.
In DAWs that support multiple plugin formats (such as Ableton Live, Studio One, Reaper, Cubase, Bitwig), the problem only occurs if you load the AU version of the plugin. Other formats (VST, VST3, AAX, CLAP) are not affected.
Symptoms
• AU plugins fail validation in e.g. Logic Pro, GarageBand, or MainStage.
• Plugins appear unlicensed or refuse to load.
• Your DAW may crash when scanning AU plugins.
