My MacBook pro is coming up on it's first anniversary.
The other day, my wife noticed a very high pitched noise, we looked around but couldn't find it anywhere. Then, I plugged it in last night when it was nearly out of power and the very evident high pitched squeal started immediately. I unplugged it and powered down and eventually the noise stopped. This morning I plugged it in and again, the squeal began.
This is new, the machine is a year old and has never made noise before.
I did apply an upgrade this week to macOS: 14.0 Beta (23A5301h)
It's very distracting. I will set up a support session at the local apple store.
