My macbook m2 keeps beeping - a chiming sound once every 5 seconds. It happened once 2 days back and spontaneously stopped. It has started again today. I was using Davinci resolve and powerpoint for a video presentation. The mac works perfectly well otherwise
Does this occur after starting up in Safe Mode?
If the problem goes away, this suggests some third party software is misbehaving. To determine what are the possibilities, EtreCheck can be used to investigate what is installed. You can post the report here. Someone might spot something.
It sounds to me like you have already isolated the problem: a conflict between DaVinci and PowerPoint. Maybe you can get further information from their respective support websites.
