I have a Mac Studio, two years old never had problems before. In the past few weeks suddenly I’m getting zapped if I touch the metal parts of cables or usb adapters plugged into the computer. Even cables plugged into the usb hub do it. Anything metal, really. I haven’t done anything different or connected anything new. This is really worrying me, what’s going on? Is my computer in danger?
Mac Studio
The Mac studio features a 3-conductor, grounded, power cord. If your building wiring and ALL the outlets and power strips and stuff you are using are wired correctly, including proper grounds, you should not be experiencing this issue.
if you are using a [ground bypass] cheater-cord, your wounds are self-inflicted.

possibly, or possibly not. there are subtle faults that could have developed in your equipment over time, such at on day one, no leakage. if the failure occurred later, but no ground was in place to keep it quiet, it may erupt and make you concerned. Faults like this could be caused by tiny leakage from power supplies. if a proper ground exists, they are immediately damped out.
If not properly grounded, you may get tingled from time to time. This is not seen as an equipment failure, but on a failure to property ground your equipment.
To provide proper complete protection for yourself, Be sure your grounding is up to standard, and no cheater cords are in use.
No, the plug it came with had a distinctly female connector where the prong should be. It looks as if it was designed to accommodate a separate grounding prong that slides into the metal-lined hole.
On the plus side, the plug did have small metal plates on either side. I purchased a different type of adapter that also has metal pieces on either side. It worked. The plug is now properly grounded and I'm no longer getting zapped.
check with the Vendor. The plug was supposed to be three conductors, as that is what is at the back of your Mac Studio.
a very minor failure in power supplies can produce the leakage you describe, but if you had the power grounded cord, you would not notice or care.
I may have an answer, but it's a bit odd. Turns out the cable and plug that came with the computer has a European two-pronged plug (despite me buying the computer in the UK from Apple directly!). There is a metal hole where the ground should be, but no prong. The adapter I have to use has a ground, but it doesn't work if the plug is two-pronged.
It doesn't explain why it only just started happening, but could be the answer. Unfortunately, I haven't a clue why it didn't come with a fully grounded UK plug, or what to do about it!

Are you sure the grounding prong did not break off in the electrical outlet? I've seen that occur once or twice over the years.
In the US, we get lulled into thinking that every power cord is molded at both ends, I know especially in the UK with different plugs, cords for appliances might sometimes be sold as a do-it-yourself Kit. But the correct plug to use is still a grounded one, and the appliance (computer) has a grounded inlet. Using something with only two pins is cheating.
Edit: I’ve plugged and unplugged things but they’re all devices I usually use, nothing new.
Thank you for the reply, but I have this issue for the first two years. If it was the house's wiring wouldn't I have had this issue since day 1?
Sorry I meant to say the issue only started recently. I’ve had the computer for two years
What is the humidity level in your location? Static electricity can become an issue if your humidity level is low (below 40%).
Getting zapped!
