Loud noise charging Macbook Pro USB-C Anyone ever had a loud noise coming from the speakers when inserting the usb charger? When I say a loud noice, I mean a screeching, metal-scraping-like sound at full volume. My volume was turned off though. I keep getting the issue until I reboot my device.

System information:


MacBook Pro (13-inch 2017, Four Thunderbolt 3 ports)
Processor: 3,1 GHz Intel Core i5
Memory: 8GB 2133 MHz LPDDR3
Graphics: Intel Iris Plus Graphics 650 1536 MB
running macOS High Sierra (version 10.13.1)`
This is something you could record with a phone (or perhaps the Mac itself) and then open a support case directly with Apple. This sort of thing could be a firmware update needed or failing hardware, but I’d hesitate to speculate on the cause of this without hearing the sound, but I’m sure it’s disconcerting to say the least.

I would be sure to apply all system updates and possibly download the High Sierra installer and run it to be sure all firmware updates are applied on your Mac if opening a support case isn’t getting a quick response.
