I also filed the corners off my MacBook

Nitpick: those are (sharp) edges, not corners. Maybe the next generation of MacBooks will also actually have exactly 90° non-rounded corners? I guess that's the next logical step...

Also, TIL that Bosch also makes files. I was under the impression that they only made powertools (or electronic measuring devices, or other things with a battery or power cord).

You mentioned Bosch and I can't think of anywhere or anyone else who'd be interested in this little bit of trivia, so a random comment on a thread about filing the edges off a laptop seems like a fitting place to share it.

Bosch dates their appliances using a thing called the Fertigungsdatum Number. The first two digits represent the year of manufacture, the second two are for the month. Except the year doesn't align with the actual year, you first have to add 20. Why 20? Well, Bosch first started using their internal dating system back in 1920 and appliances from that year started with the code "00". I had an oven that had a date of "7808", which means it was manufactured in August 1998 (it lasted almost 30 years before we finally had to replace it last month).

In 2020 the system wound back around and started with "00" again.

And the majority owner of Bosch is the Robert Bosch Stiftung (Robert Bosch foundation), which uses its dividends to fund projects in social sciences, public health and education.

Oh, Bosch makes all kinds of things.

Bosch's logo is something like a sparkplug (the thing used in internal combustion engines). To this day, the 'mobility' division is the biggest one. See https://www.bosch.com/stories/creation-of-the-bosch-logo/

Decades ago I actually had an offer to work for them as a research student working on optimising internal combustion engines.

not a spark plug. They call it "armature in a circle", but that's somewhat generic.

Bosch used to do the first magnetos / dynamos in the early 1900s motorbikes / cars. The principle is similar to this day - one rotating magnetic field within one static. You can do all kinds of shenanigans and combinations of permanent magnets / coils where it's either the electric current generating a magnetic field or the magnetic field generating an electric current. Depending whether You want the movement to generate electricity or the electricity to generate movement.

In the first magnetos (the thing that uses the engine rotation in order to generate a current that then makes a spark in the spark plug) they used permanently magnetized exterior plating and a rotating winding. That's sort of what You see in the logo - two coil windings rotating in their housing.

I've been using Macs for decades and never had these issues personally. It seems like some people do literally rest their hands / arms on desk / notebook body while typing.

The "sharp edge syndrome" here to me seems to be a good thing then as it acts as a reminder for proper ergonomics / posture.

First Google AI search result on the topic:

"Never rest your wrists on your MacBook while typing. Instead, let your palms rest gently on the laptop body only when you pause. Hover your hands as you type. This prevents you from bending your wrists and protects the nerves in your carpal tunnel."

That also pretty much exactly mirrors the way we learned typing / posture at school in Austria.

Great article and happy to see that I'm not alone. I don't get why on such a well thought-out and built device as this, the corners are so sharp.

From how I use the trackpad, the bottom of my thumb always feels sore-ish after a day's work and it took me a while to trace this to the sharp cornern of my macbook.

I love the animation on the background of your website. And I totally understand what you mean about using a tool, if it's too delicate to do the job, then it's not doing its job. Imagine buying a hammer and trying to keep it clear of scuffs, it's obviously going to impede your work.

Yeah I think the grief OP was getting over that statement in some of the other comments is unwarranted, I understand completely what they mean about tools. You have people who buy expensive guitars and barely play them for fear of scuffing them for example, depriving themselves and the tool of the thing it's actually for. I'll never understand that mentality.

I don't like to be precious about my tools either, scratches and so on are evidence it's being used for what it's made for!

I'm probably missing something here but if I have to worry about getting an expensive watch that calls it "Submariner" wet of all things, at the very least, it's badly named.

I think the bigger point is that people think they “afford” a luxury item as soon as they barely afford to buy it and forget that owning also has a cost. They are too afraid to use the damn thing out of fear that they damage it somehow. Their luxury item loses all meaning and use beyond showing ownership of an expensive thing.

Like those fancy luxury cars some people buy but are too expensive to drive, maintain, insure, or repair. One scratch wipes out their savings so the car sits in the garage.

I bought a 1973 Fender Jazzmaster that was immaculate and should have been my forever guitar. I was so afraid of "ruining the value" that I sold it. I couldn't play it, I was so paranoid. It got into my head. Instead, I ended up buying a '65 AVRI Jazzmaster body and put on an EGC aluminum neck and a Tuffset bridge. The price was about 2/3 of the vintage one, but I have no qualms about playing this one. ¯\_(ツ)_/¯

Yeah the sharp edges have bothered me since they started with the unibody. Luckily I'm completely off Mac these days. But really the last mac I enjoyed using was my powerbook. It had really nice plastic gaskets for the edges, a keyboard with really good travel and cupped keys, it was wonderful.

I got a plastic MacBook eventually which I filed down too because the edges were really sharp there. And plastic is easy to file. Also replaced the screen with a matte version, on the plastic MacBook that was also easy because the screens were readily available and there was no glass overlay.

Then I had a unibody MBP 15" matte. Less sharp and with off factory matte display. Not great keyboard though.

The current MBP I find abhorrent. Even after they switched from the horrible butterfly mistake the travel is still way too shallow. I just can't work with that anymore. These days I just don't buy laptops anymore. Only desk PCs.

On a similar note, people are way too precious about their dead-tree books. Feel free to chuck them in bags, make notes in the margins, fold pages, underline, and strike through text in them. It's yours. Make it yours! Your scribblings don't detract from what's in there – they elevate it to something unique.

(This is particularly true if it's a book that's still in print, or was in large enough print runs it's easy to buy another second-hand copy when the one you have falls apart. It's still somewhat true even when that's not the case.)

Three employers in a row insisted on handing me a macbook, and three times in a row I ported Gentoo to it out of pure spite and disdain for third parties trying to control the binaries I use to do my job.

At the time they called this crazy and unproductive, but those obsessions with control of my tools built the foundational skillsets that drove my career.

I strongly recommend against using a deburring tool on a Macbook. IMO OP has picked their tools with perfect consideration.

These tools are made to remove burrs resulting from machining processes. They are very useful for quick&dirty jobs on bore holes or rough edges where optics don't matter, but they lack the precision for sensitive work.

Anybody who's not very well versed in using a deburring tool is just about guaranteed to produce a terrible result that will only take longer to sand out than approching the task with files and sandpaper.

The Helm is great. I'm not sure it really solves the wrists problem, at least for me since for how I use it the height of the laptop makes a huge difference in ergonomics. The MacBook Pro is already tall, and the Helm makes it taller, creating pressure on the wrists. Meanwhile I don't have this problem on my carry everywhere MacBook Air since it's so thin.

Calling it a tool is fine.

Some people would like to pretend means of production are holy assets you're supposed to value and trade (INVEST!!! making value is for losers and _these_ workers), when it's just a consummable that should serve a purpose right now.

A computer is a tool and customizing the case is not unheard of.
