FYI I installed MacOS Monterey 12.5 Beta (21G5046c) and the clicking and popping is still present, and as bad as ever. I just bought this Macbook Pro 16" 16GB at Best Buy so I am probably going to return it. The sound of that clicking popping every time I do something intensive, like compiling or loading an app, is so horrible. It makes my dog bark.

This was driving me crazy and it turned out to be Unity when it's set to Development Build. It will try to connect to the profiler and trigger this message on all Ad Hoc iOS builds.
