Hi Hogman,

Please do this:

1. Open a Terminal window. One way to do this is to press Command+Spacebar (this brings up spotlight), and type "Terminal", then press enter.

2. In the Terminal window, first type (or copy and paste) the following command and press Enter.

auval -a


This will list all of the AU plugins installed on your system. Verify that you see in the list somewhere: "PG Music Inc.: Band-in-a-Box DAW AU Plugin
Does it output any error messages?

3. Next, type the following command and press Enter.

auval -v aumu Oaw8 Manu


Note that is a capital O, not a zero, in Oaw8

This will test the Band-in-a-Box DAW Plugin specifically. Copy everything it says (maybe about 50 lines or so), and paste into your reply. You can copy text in the Terminal just like you would expect, by dragging to highlight, and press Command+C to copy.

I'm assuming it will list some sort of error message, which we would like to see.
===============================

There is one other thing to try as well in the meantime, although I don't think this will make a difference since you experience the same problem in a different user account as we found out in our test earlier. But for what it's worth:

- Go to ~/Library/Caches, and delete the folder "AudioUnitCache". As a shortcut to get to this folder, you can press Command+Shift+L. This hotkey gets you into the user "Library" folder, which you don't normally see because it is a hidden folder. From there, you can open the Caches folder and you should find that AudioUnitCache subfolder in there.

- After you do that, back in the Terminal window, run this command (or alternatively reboot the Mac):

killall -9 AudioComponentRegistrar


- Then, run the auval scan again and see if there's any difference.
