AU not showing up in garageband

Hi everybody,

I recently decided to get into coding my own plug-ins and since I mainly work on garageband, I thought I’d start with the AU format. however for the past week I have been debugging to no avail - numerous AU cache clears, auval commands, config edits and plist file checks. If anybody encountered a similar problem, I’d be thankful to know what finally fixed it or even better, a foolproof step by step tutorial on how to get my plug-ins to show up in garageband
