Unable to load demo version of Serum on mac after macOS update

Started by axelm73

I've been using the demo version of Serum on my mac for GarageBand and its always worked fine. However, with the new High Sierra update, I keep getting a message saying that 'Audio Unit plug-in can't be used' and 'The Audio Unit “Serum” could not be loaded for your project, and may need to be updated.' whenever I load a project or try to initialize a new instance of Serum. What needs to be fixed?

The demo version is for evaluation and will not save in projects.

Warm regards,
Steve
