Currently experiencing this problem, which happens to me once a year it seems, then I fix it and forget how to fix it when it occurs again.
My setup:
MacBook Pro, 16-Inch, 2021
Chip Apple M1 Pro
Memory 16 GB
macOS Sonoma 14.3.1
I use a MX Master mouse and MX Keys Bluetooth keyboard. The MX Mouse is plagued by a hardware issue that can be fixed by opening the mouse and adjusting a tension screw… however if others are experiencing the problem with other devices, this may be OS related.
Recently, I noticed that the mic icon appears in my Finder tool bar, randomly, as if some process is firing off in the background that is interfering with Bluetooth. Randomly, my mouse cursor stutters and jumps around for seemingly no reason.
If I rediscover the solution, I will make a YouTube video on my channel (@wepiphany). Has anyone found a solution or cause?
