alt Hacker NewsFiling the corners off my MacBooks
Comments
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-worker 4: The only downside I see is that you can no longer say "Hey, that's a sharp-looking laptop!"
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.
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.

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.
Not just sides, the vents are much sharper.
Few years back, I tried to look on reddit for complaints regarding this - barely anything.
Maybe I'm autistic, but I loooove the sharp edges near the opening. They've become almost a nervous tick of playing with them with my fingers.
I've got no idea why, but the sharp feeling is amazing.
There are plenty of laptops out there that have square edges on the user-facing edge. However, most are tapered and/or have hinge designs that tilt the laptop surface towards the user, dropping that square edge away from the user's wrists.
Most Apple laptops, such as the latest Pro's, are level, rather than tapered, and sit flat so that the user-facing edge cuts into your wrists. It's bad ergonomics, plain and simple. If you value function over form enough to modify your tools in this way, choose better tools.
Love this! I did this in 2020 and until today I hadn't seen anyone else who had done it. If anyone is tempted, I recommend finishing the job with Micro-Mesh. IIRC, I went up to 12,000 grit and it results in a nicely polished look that catches the light beautifully.[1] I bet it would look even more striking on the actual black MacBooks we have today.

Nitpicky, but he’s rounding the edges, not the corners.
And yes, why are they so sharp?
I seem to recall my wife having the plastic MacBook that came out circa 2006 and the edges on that thing were legitimately painful.
I always marvel at how sharp the points are on the notch of the lid on my current MacBook. Very very pointy.
Lovely writing! And I think the understanding that one can and should modify their tools to their needs is rather rare and should be appreciated.
Mac users since 2010. Never noticed the sharp edges. I am just keen on not having that little red ball in the middle of the keyboard á la Elitebook.
I use a case on my MacBooks to protect them from damage. These cases are made of softer materials that are easier to chamfer. I make a similar modification when necessary. Sometimes it's worse with the plastic cases because the injection mold seam is that sharp edge.
There's a more thorough version of this at https://www.youtube.com/watch?v=RSaJAAqSAMw and the end-result doesn't look as tacky
As I'm typing on mine right now, I wonder why they made these so sharp. It hasn't cut me yet, but they are decidedly uncomfortable.
I thought this was going to be on a softwarefix for the appalling inconsistency that are macOS Tahoe window corners. What I found deeply disturbed me, though I must agree, the edges are a bit more sharp then I'd like and a slight curvature could probably prevent them showing wear and tear [0]. Good on op for doing something they like, even if it's really out there and I could see more "pillowy" hardware becoming a thing now, after a few years of sharp edged devices.
Since I mentioned Tahoe, it bears repeating, my spotlight is still broken.

Somebody should offer a service to chuck up Macbooks in a CNC mill and hit them with a chamfer tool
Too bad my Mac is company owned, maybe I'd use it in a "laptop mode" more if it didn't slit wrists.
I did this on the macs at an old job, but not as drastic. It really doesn’t need much to ..ahem… take the edge off.
As a bonus the machine looks like crap so it’s far less likely to get stolen.
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?
I just came into Mac world for work and struggle to understand the choices Apple makes:
- Sharp edges eat into my forearms.
- Glossy screen makes it hard to see when it's light out.
- The keys have a real hard stop when you press on them which tires out my hands.
- An arrogant desire to obsolete ports.
I don't understand the appeal of the machine, it feels like style over function everywhere.
Doing this to a work computer seem a bit questionable from the ethical standpoint.
Totally fine to do whatever you want to your personal belongings though.
>it is uncomfortable on my wrists
Are your wrists supposed to be coming into contact with that? I suspect many of us have bad posture and do rest our wrists like that, but if your concern is wrist comfort, you probably want to consider that you're going out of your way to enable harmful posture.
> This was on my work computer.
Bold move to do this on your work Macbook. I'd be too worried of getting chased down with a bill when returning the laptop eventually.
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%.
I'm not brave enough to try this on my own, but I applaud the effort. I'm pretty sure I'm developing lasting calluses on the underside of my wrists from all the constant rubbing against the sharp edge of my MBP.
I wonder if it would be possible to sand down a MacBook surface to the grade where it was all shiny mirror like the Apple logo, e.g. with car polish :-) The "untouchable" MacBook mirror :-)
I've done this to my MacBook around the sharp and unpleasant corners near the touchpad. I had the laptop a few weeks before I couldn't take how unpleasant it was to touch any more.
I've been meaning to do this forever and think this game me the push I've needed to do it tonight when I get home. Probably not as rounded as OP, but it's reassuring to know I could go that rounded and it wouldn't fall apart.
This is very interesting Maybe I'll do this when my mac is a couple years old haha
A hero post. I'm pretty sure we'll be able to shave using the edge of iPhone Air 20 or whatever they are coming up with. iPhone Stiletto.
Did the same for my Macbook Pro 15 unibody circa 2010. It was a great QoL improvement.
Love that he took it so far. I filed mine a while back - it’s so much more comfortable to use. When I drop it and a corner get mashed, I file that back flat. It reminds me of kintsugi where it shines from the fine filing.
I filed my work dell laptop too. Very different feel, but it is nice not living in feel of your own stuff.
Physical objects should be rounded, virtual windows should be square. I will die on this hill.
Yea, that's ugly. I'm sure it could've been done more gracefully with 15 minutes more effort. But judging from the general wear and tear on this poor Mac I guess they don't even consider the resale value.
A very even 45 degree cut, like the cut to lift the screen but much shallower would look pretty cool. Maybe 2mm wide
Sitting in a reclined position on the train, I’ve had a MacBook fly into my face when the car lurched and slice my nose open. Bled all over.
Depending on how I'm using the computer, I may definitely have deep marks after working laying down, but if I sit in a wood chair for a while it's the same thing- and my forearm is much tougher than behind my knee.
I suppose I would prefer it nice and rounded and soft on my wrist - but I don't feel like it's quite as extreme as this thread would have you believe lol
Everyone should be personalizing their belongings to suit their needs and desires. Living with belongings that make you feel anything less than happy and satisfied is NOT necessary.
This is a particularly hilarious customization both for its combined utility and shock value and also for doing it on a work computer.
Would be cool if somebody would make a round over or chamfer plane that would allow you to remove the corner with a higher finished look.
I did this at my last job, it's nice.
One of the ATPers was going on and on a bit ago about how the Neo is very "rounded" and "not sharp" compared to the Pro. I wonder if it would need this.
This is the spicy content I come here to read. I wouldn’t do it myself but god speed to anyone who does.
The sharp and high edges leave a mark in my skin. The older MacBook Air design was lower, so resting your palms wouldn’t give me this
Maybe it's just me, but I think it looks kind of cool. I like how it tapers from the ultra-smooth front to the jagged back edges. Only suggestion would be to use better tools to do the filing, since it looks a bit uneven/rough.
The author has the same problem as myself; there’s a permanent imprint on the screen that sits right where the screen makes contact with the topside of the touchpad.
It’s quite an annoying flaw, and i’ve only had this problem with the machines since the M1 redesign
At one point due to the way I was using my just above my wrist my skin basically calloused from the edge of the macbook. Now at least the lid is not that sharp but it used to be I recall and I always worried about kids getting hit by it in case of an accident.
Truly the most horrifying post on HN I've seen in quite a while
I used a macbook for almost 2 years and genuinely don't understand how people can tolerate these machines. My wrists would be cut up all the time to the point where I looked like I was self harming myself and the glary screen is entirely unsuable anywhere but a darkest basement. Not to mention the terrible keyboard. To this day I'm perplexed how macbooks have such high desirability by full time developers when they're almost unusable.
