Soundflower + AU Lab Mojave?

Solution 1:

The only reliable way this would work is to manually edit the TCC trust database:

sudo sqlite3 ~/Library/Application\ Support/com.apple.TCC/TCC.db "insert into access VALUES('kTCCServiceMicrophone','com.apple.audio.aulab',0,1,1,NULL,NULL,NULL,'UNUSED',NULL,0,1541440109) ;"

Solution 2:

I found this thread on Apple's Support Communities: AU Lab Not working on MacOS Mojave .

There's an answer that states:

Update: I was able to make Au Lab show permission request, finally. I think the reason it didn't ask permission before was that it was somehow cached since I had Au Lab in my /Applications before updating to Mojave.

It did request permission when I downloaded new version from iTunes - Mastered for iTunes - Apple (CA), unzipped it right in my Downloads folder and launched it from there, without moving to /Applications folder. That's when it said it's an app downloaded from the internet are you sure bla bla and then when I created document it asked for permission.

After that you can delete Au Lab copy from Downloads and continue launching from /Applications — it'll work.

Downloading it and replacing it with the new one from Apple also worked for me.
