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

Huh, I've had that pitting with every magic mouse I've owned, the sides of it end up looking like a cheese grater...apparently my fingers are acidic!

Have you ever had that looked into it maybe just ask AI? That does not seem healthy.

Holy moly, that guy in the reddit post needs to see a dermatologist asap and figure out why their skin is emitting acid.

Thanks for this interesting post - I've been showing it to co-workers to get their reactions, which was incredibly entertaining for me! Co-worker 1: Interesting. I wonder if that voids the warranty. It's Apple you know. Co-worker 2: May Jobs have mercy on their soul... Co-worker 3: Not a bad idea. But not sure if that would cause problems with structural integrity of the laptop, like if you drop it or something. Co-w…

It's a work laptop - I'm surprised none of the coworkers said "you'll get in trouble when you return it".

I don't know WHY... But corporate bureaucracies have logic of their own.

Not to well actually your well actually but they’re all anodized to prevent corrosion and scratches (the oxide layer is harder than the underlying aluminum) - the silver one is just undyed.

And in the pictures you can see a clear color difference between the anodized silver body and the exposed aluminum. It's subtle from a distance, but if you zoom in a bit its pretty obvious

That difference will fade with time.

The pictures were taken months later, so some fading already happened

> It's easy for me to feel the mains frequency while gently rubbing the top surface of the MacBook I haven't been a regular Mac user, but I've had maybe 3 work MacBooks since 2010 and I recall having this issue with all of them. Why haven't they fixed it?

They can’t, it’s caused by the capacitors required to suppress electromagnetic interference caused by the switch-mode power supply. These allow a very very tiny amount of current to leak through from the mains side, which is then capacitively coupled to the metal case (IIRC Apple do not connect the case to power negative) reducing it further, but it’s enough for humans to sense it. It can be avoided by using a ground…

Definitely been a long standing issue on many laptops with exposed metal parts. Late 90’s, if I used my brother’s Compaq while putting my feet up on the radiator, the metal speaker grills would give me mild shocks.

I switched as a long time Linux user to a MacBook because of the hardware: - Battery: no other laptop comes even close - Trackpad: I don't use a mouse anymore, no other laptop comes close - Audio: No other laptop comes close "Sharp edges" really don't bother me to be honest, I wouldn't have noticed it if nobody told me. I have a nano-texture screen, and it works great in daylight. Just goes to show how opinions can d…

My only complaint is with the EN-international keyboard my company prefers - there is no way to reverse the tilde key position back to the same place next to 1 on the US keyboard. The OS knows what keyboard the laptop has and refuses to change it.

I've created my own keyboard layout plus do some key remapping on my mac. Are you sure this won't work for tilde?

The tilde key exists in the key map here: https://developer.apple.com/library/archive/technotes/tn2450...

You can see how I did mine here if you're interested: https://github.com/bruse/dotfiles/tree/main/macOS (I suspect com.local.KeyRemapping.plist is most interesting, but the key layout file is there too, with some comments on how it was generated).

i’ll take 3. we can be boring together

I strongly suspect 3 is correct - removing material from the corners might weaken the structure. I would use a CNC machine to round them more precisely and uniformly though.

Haha I was thinking the same when I read he hand filed it

Nice initiative but I would personally prefer adding some kind of padding, which is an easier solution to the problem, not as drastic, reversible, and less controversial. Unless doing something controversial is one of the goals here, which is also fair.

How are you gonna close the lid when there is padding in the way?

> This was on my work computer

is this an employer-issued computer? Like if I did something similar on my DELL laptop (us lowly devs at %DAY_JOB% don't have Macs), management would be up my ass the minute they saw this, if only because the maintenance agreement the company has with our supplier will likely be voided for my machine.
