What’s your version of Mac OS ? ( version name + build )
IE: Mac OS High Sierra version 10.13.6 (17G65)
Your Logic Pro Version ?
Are you using latest A.N.A 1.5 release ?
Also make sure that you’re using the x64 plugin version of the plugin if working with a 64bit system & DAW.
So check if you have the following plugin file A.N.A x64.component in this folder:
YourmacOSHDD/Library/Audio/Plug-Ins/Components
Also checked that you’ve downloaded your license key file from your account and that A.N.A is correctly authorized. ( maybe you’ve got another VST based Daw or App to check this next to Logic )
Attached is a .zip txt file of a correct AU Validation Tool result on Mac OS H.S 10.13.6 and latest Logic Pro X 10.4.2 for A.N.A v1.5 Audio Unit A.N.A Validation Result.zip (3.0 KB)
You will find path information in there, be sure to use an app like the free Permission Reset or BatChmod to reset permission of the following path YourmacOSHDD/Library/Application Support/Sonic Academy/ , restart your computer and open Logic again, go to Preferences/Plug-in Manager find A.N.A and highlight it and click on the “Reset & Re scan Selection” button on the bottom left of the Plug in Manager window.
