M3 Pro 14” MBP Electric shock

My wife and I just upgraded to the 14” MBP with the M3 pro chip. Both our computers are demonstrating a serious safety issue. When plugged into AC power the chassis is live with ~ 45-50VAC. You get a tingle when touching either of them. They are on separate circuits in the home and each outlet has been tested and is properly grounded and has correct live / neutral wiring. I have measured using a digital multimeter set for VAC and am measuring between the ground on the AC outlet and the chassis of the computer. It does not matter if I’m using the Apple power supply that came with the computer or power delivery through the USBC port.

Two computers, two power supplies, alternate power supply, two electrical circuits, same issue. This appears to be a design flaw or manufacturing / QC issue. This is not safe and should never have been sent to consumers. Is there a Consumer Protection mandated recall on these?

MacBook Pro 14″, macOS 14.2

All Apple service programs are described on this page: Apple Service Programs - Apple Support.

In an abundance of caution you should stop using that Mac. You should have Apple evaluate that Mac, its power supplies, the cables used... everything. Contact Apple Support, here: Official Apple Support.

I’m planning to try another building just to rule out the electrical despite it all checking out. So strange that both devices are doing it. FWIW, we have separate macs for work that are about five years old and neither of them have this issue.

Hello.

I suspect if you purchased your devices together they may have a hardware defect. I would contact Apple Support. Have you tried using different chargers? Don't rule out that possibility.

Merry Christmas,

Did you try another building?

If this was a systemic problem these communities would be flooded with reports similar to your post.

Have the computers examined by an authorized service center.
