The title is misleading: this only modifies the desktop rounded corners, not the app window corners (heavily discussed recently at HN and elsewhere).

The blog post about this is slightly interesting, but mostly feels like a candidate’s position paper on rounded corners, rather than an newsworthy or technical explanation: https://medium.com/@makalin/reclaiming-the-screen-a-develope...

The core innovation is the ctx.fill calls here: https://github.com/makalin/CornerFix/blob/main/Sources/Corne...

And the screenshot in the blog post is of a window with rounded corners!

> There’s also a consistency problem. If you use multiple monitors or virtual machines, the mismatch between macOS’s new roundness and other systems’ sharper corners creates visual friction. Once you notice it, you can’t unsee it.

I guess it's a good thing I never noticed it then? Of all the very real problems with Tahoe this one would never have even registered with me.

I still have no idea what this does. What on earth are the desktop rounded corners?

Macs have rounded corners on the desktop. I.e 4 corners. It looked awesome in the CRT days because of the shape of them. These days on flat lcd screens the geometry is so good that they aren’t required to provide the same function as in CRT days but some people still like the look. I do, but i dont run extra software if i can help it especially for an aesthetic change. I used a tool like this is the past but there were incompatibility’s.

I'm super confused. My Macbook desktop has no rounded corners. Both the menu bar and content against the bottom edge are sharp-cornered. Is this only for external screens?

Running an Apple Studio Display here, and no rounded corners at any edges. So, just for non-Apple monitors?

Not the case with a third-party display either.

Not even that. I have both Apple and non-Apple monitors, and my Mac only rounds the top edges on the MacBook’s screen, as intended.

Not sure what this tool’s function is supposed to be, given that the rounded corners only appear on screens that are actually rounded. Why would you want to straighten that out on a physically-rounded screen?

It’s more than that, the screen is rounded at the hardware level, there are no pixels to show anything here. What the OP software is supposed to “fix” CANNOT be fixed!

Running two Lenovo ThinkVision displays off of my work MacBook Pro.

On the MBP built-in display, the upper-left and upper-right corners are rounded. I believe this is due to the shape of the display. The bottom corners are not rounded.

On the external displays, the corners are all square.

The newest design of MacBooks with the notch have the top corners of the display rounded.

Do those pixels even exist on the display? They certainly don't on the iPhone; the implied corners on those are physically outside the device.

Yeah I really thought (and actually still think) the rounded corners on the top left and right of the new(-ish) MacBook Pro are hardware. I know for sure they pre-date Tahoe!

They are hardware.

There's software like Top Notch if you want to make the bottom corners rounded also.

TopNotch also solves the problem this app targets I think: the rounded corners are not visible when the menubar is black.

Yes, but that’s not in-software, the screen is actually, physically rounded. Using software to straighten that out would have, quite literally, no effect at all on these machines.

But most importantly, when connected to sharp-edged monitors, the Mac does not round the corners and instead displays the entire contents of the screen edge-to-edge (including the desktop and menu bar). So this tool seems to be solving a problem that does not exist.

Modern MacBooks models have rounded corners at the top right and top left corners of the screen, see [0]. The bottom corners don't do this and external displays don't do this. This is a stylistic choice to match the curvature of the laptop's edge. If you move your mouse along that corner it doesn't disappear behind the curve, it follows the curve.

I really think* the rounded corners on top-left and top-right of the MacBook Pros are hardware. There is no software in the world that can “fix” that…

* Try to move space on such a device, the non-rounded desktop appears…

The linked article on medium was also written by AI, which immediately disqualifies it from being interesting or useful.

"And the worst part? Apple didn’t provide a switch to turn it off."

Now see, this is AI. A normal human being would write, "Apple didn't even provide any way to switch off this non-feature" - for example. AI always, for reasons that are likely neither interesting nor especially illuminating, writes like this. Unnecessary and stupid stylistic choices everywhere.

Look, if you cannot be bothered to write something, why on God's Good Earth would anyone bother to read it?

I'm not saying you're wrong about this article being AI-written, but I know people who write like this, and I hate it.

Exactly. AI wrote this way because humans wrote this way. Just as humans used em-dashes long before AI was a thing.

If AI does this, it's because it's ingested the last 25 years of bad internet headlines. Written allegedly by humans.

And to be honest? It’s really annoying indeed.

I like it. A lot of times I just skim, so sentences like this let me know when to pay more attention to some point the author is trying to make.

Is this the new em dash witch hunt?

I sometimes write like that because I noticed for regular people, they tend to pay more attention if some things are written a specific way. It’s like an FAQ.

I’ll continue to use bolded titles and bullet points when writing for a regular audience.
