I got shocked. Picture of testing device showing the current flow from a cable: https://ibb.co/YbqtgVX https://ibb.co/YbqtgVX Anything attached to the macbook port is causing shock on the exposed parts while it is plugged into that charger. I wouldn't call it safe. If you read some of the bottom answers, they also elaborate on the same topic. Furthermore, I don't live in UK and there can be different electrical standards in terms of wiring. I don't face this issue while using the grounded charger hence it is limited to apple charger which I double checked for missing ground support.

You can also get shocked by rubbing your feet on carpet and touching a doorknob. Are those also unsafe? Should we be panicking about our house? You’ve jumped to a wild and accusatory conclusion.

It’s nano amps at a moderately low voltage you’re able to feel, it isn’t unsafe, you just happen to be aware of it. The Apple chargers people often discuss this effect with are some of the most crazily over engineered available in terms of electrical safety and are used in every country on the planet. They have the X class capacitor which causes this effect to meet RF emissions regulations.

  This is the correct response. Unfortunately it's my concern that rather than work to fix the underlying issue or learn to live with it, we'll continue to get FUD spread by people like OP. Ultimately this will lead to people going out and buying knockoff chargers with a 3rd pin and none of these EM filtering or other safety components. I've seen this for at least 10 years come up again and again, Apple should just sell an India edition Macbook with either a plastic case or a sleeve to avoid people complaining since there's no interest in addressing the cause.

      While many on HN likely consider it pretty gauche, to say the least, to be racist towards certain minority groups whose struggles Americans tend to have more awareness of, I do still see the subtle—and not-so-subtle—racism and prejudice regularly, especially when it comes to Asian groups, be it towards Arabs, like myself, Indians, Chinese, and many other people. So, I get the frustration. However, that said, even if you intended for others to take your comment rhetorically rather than genuinely transphobically, to highlight how bad what the other person said sounds to you, I think it’s misguided at best; trans people get attacked enough as is, and I don’t think there is any need to bring imageboard slurs [1] into the mix to get the point across. I don’t mean for all of that to come across as “virtue signaling” to distract from the original problem of racism by solely focusing on the transphobic language. The reason why I’m not ripping the parent comment apart or flagging it is that I interpreted it completely differently; I didn’t take it to be subtle racism toward Indians, as if they need to be “fixing the problem” (of not understanding the actual level of danger?), but rather that because Apple is seemingly so uninterested in addressing the issue, sarcastically, they should ship plastic laptops instead. Maybe this is too generous of an interpretation? I don’t know. But yeah, worth considering the other possibilities. [1]: tbh, I’m not sure if we can refer to verbs as slurs or if they are solely nouns. I can’t actually think of another similar verb to compare (Maybe this is my wordcel moment). You get the point, though.

        People just want shit to complain about, if they can't discuss technical issues and provide explanations/solutions it'll be social ones instead. I wasn't kidding about selling a case or making the case out of plastic or coating the outside with a rubberized material. Apple chose to be the odd manufacturer going all metal and that leads to unmasking issues like this. I would wonder whether it's cheaper to ship a 3-prong or a silicone sleeve for the laptop. Telling India to fix its electrical standards to avoid this annoyance is just as futile as telling Americans to bury their electricity transmission lines. Even if it was codified it'd take years for components to get replaced.

I'll have to agree with Apple defense force posters who downvoted you on this one, getting tazed is the thrill of using ungrounded appliances. By ignoring safety concerns, they can save on components, which saves on CO2 emissions.

  > "By ignoring safety concerns" OSHA have an interest in electrical safety[1] - "Electricity has long been recognized as a serious workplace hazard. OSHA's electrical standards are designed to protect employees exposed to dangers such as electric shock," and they call out ground faults: "The following hazards are the most frequent causes of electrical injuries: contact with power lines, lack of ground-fault protection, path to ground missing or discontinuous".

I have owned a ~2012 metal macbook pro in the past and felt the buzzing as it was charging, and would not call that effect a shock (there was no spark, it never hurt, I never got burned or needed a doctor's visit), so if you are being shocked then your situation sounds worse - and different to the buzz most people are talking about with respect to metal macbooks. (As a kid there were some field telephones[1] in the house, they are ex-military phones you wire directly to each other and they have hand-wound generators which power the other side to ring; we used to play a game of "how long can you touch the contacts while winding it" - that was uncomfortable but had no safety effects that I know of (no burns, bruises, doctor's visits, etc). Even being shocked is not automatically unsafe, although it may be unpleasant and undesirable from any consumer product, let alone premium ones).
