In our tests, macOS Sonoma 14.5* has been compatible with all of our supported** plug-ins.
We would still recommend inquiring with companies that are developing the DAW that you use about compatibility before upgrading to make sure that the DAW is compatible.
* There was an issue with occasional high memory usage in some earlier versions of Sonoma.
** Products that still are available for purchase at toontrack.com, and not discontinued products.
