I've filed FB13497581 on this topic. But Ever since macOS 14 (or perhaps one of the releases that came after), my machine (M1 MacBook Pro) frequently locks up the UI. Sometimes it's so bad the mouse won't move. It only lasts a few seconds, but at its worst it happens every few seconds. It usually manifests as no text appearing as I type (which sucks, since I write code all day).
I'm fairly certain configd is to blame. When this occurs, configd is using nearly 100% CPU, and spams logs with thousands of messages per second.
Killing it does nothing. Rebooting might fix it for a bit, but it eventually comes back.
I'm wondering if there’s some on-disk state I can **** away to start SystemConfiguration from scratch. I hate to do that in case someone from Apple asks me for files to analyze, but I feel like my FB is just going to languish. Meanwhile, this is rendering my machine unusable.
Or if anyone knows how to interpret the log messages.
