it temporarily solves the problem it will come back. you will tell us ... please.

Same for me. Apple is no more what I expected from them.

Many of us have already tested Boom2, and the problem, even if it seems delayed, is still present.

I suggest to wait for a few days/weeks before being sure that's the fix. We had very similar answer by installing Boom software from Global Delight https://www.globaldelight.com/ Many people thought that this fixed the problem, but in the end it did not. This said, I will try your suggestion to see :)

Just crackling again after 13 hours (eqMac installed)
