If you've come across the warning stating: 'The Audio Unit 'XXX' could not be loaded for your project, and may need to be updated...' then before you throw anything at your Mac's computer screen, breathe and read on to discover a temporary solution that'll help you get around this security/sandboxing issue.
I am running Mavericks om my Mac and using Garageband 10.1.2. I want to update my computer to MacOS High Sierra, but I do not want to change my Garageband version. Does Garageband get updated along with the High Sierra update of MacOS?

And if you use Logic Pro X or any other DAW your plugins should load absolutely fine there. This is just a GarageBand and macOS High Sierra issue.
