I just did this to my MacBook not because of the sharp edge but because the pitting turns a sharp edge into a sawblade. Something about the grounding on on the frame when plugged in mixed with my sweaty hands leads to damage along this sharp edge on every MacBook I've ever owned. See https://www.reddit.com/r/macbook/s/hbyVh5SJhw for another poor soul with the same caustic skin

I’ve been traveling around the world. It is 50 / 50 of the socket is properly grounded —-anywhere in the world. I get a tingling zap on the wrist when not properly grounded. The charger also gets hot and sparks.

That should not happen with a well designed power supply. It sounds like Apple cut some corners "for design reasons", or some shortcut to make it cheaper to manufacture.

Not all heroes wear capes. This is excellent and can't wait to get aluminium mac next to try it – don't think Space Black is a good way to go. Author's another post on "The Seasons are Wrong" [0] is excellent too and I fully support both approaches. [0] https://kentwalters.com/posts/seasons/

The seasons idea is interesting -- to me, both proposals feel wrong. I think it's because the weather changes that I perceive seem to lag behind the changes to daylight length by a few weeks. I would propose boundaries that align partly with how I perceive the weather, and partly with how we plan our year (by months): Summer starts June 1st, Fall starts September 1st, Winter starts December 1st, and Spring starts Mar…

That's how it works in Australia, though rotated six months: Summer starts December 1, Autumn starts March 1, Winter starts June 1, and Spring starts September 1. I think it even has legal status. In the North of the country though they typically just use wet and dry season.

I've also always thought that the equinoxes and solstices should be the middle of the seasons, so using the 'cross-quarter' days as the beginning of seasons makes more sense.

Earlier quoted context omitted.

Oh is that why it happens? Was wondering why the spot directly under my wrist was pitted into a sawblade. I also filed it, though just enough to remove the pitting, nothing like the OP did. It's easy for me to feel the mains frequency while gently rubbing the top surface of the MacBook while it's plugged in. Really feels unsafe, but neither me nor the computer have suffered any serious injuries yet.

Using a 3 prong extension cable on the charger will prevent this.

That cuts it by about 90%. But as others have said, the default US plug doesn't ship with a ground pin (though the extended cord does IIRC).

Cool, but why is the most rounded-off part in the center? My wrists cover the edge at 5-25% and 75-95% when typing. When mousing, my right hand fleshy pad covers the edge at 65-80%.

The takeaway from this article should be to consider modifying your tools to your needs even in unconventional and controversial ways. I love it. The flame war on whether the original chassis design sucks or rocks is not that interesting.

25 years ago one of early engineering courses included a case study about Ingersol Rand (IIRC). They went out to work floors and saw how all the workers had modified their air wrenches in the same way, adding padding with tape in various areas. They realized they could probably make a better wrench if it had some of those ergonomics built in. Maybe the next phase of Apple could return to flowing shapes and save our w…

I feel like this is only a problem if you’re keeping your wrists at an unergonomic angle. I’m not saying that everyone is perfect all the time but like this is barely an issue if you’re sitting at your desk?

Yes. I keep mine on my lap. My regimen is that I wake up at 3am and lie on the couch for several hours with coffee and write code (or these days, ask "someone else" to). It is highly productive and enjoyable and breaks all the rules and no I do not have RSI. Long ago I started sandpapering the edges because yeah otherwise it hurts my wrists.

Does Europe and America really call the summer solstice the “start” of summer. Wow. In India our summer holidays start at the end of March and finish in the start of June. That’s usually our hottest months too. And a lot of our regional “New Year” calendar’s and related festivals are on April 14th and can probably be considered the start of summer.
