    Your GitHub repo and the associated medium article do a great job of describing the problem and the solution that you settled on. I don’t understand why you didn’t include a screenshot of what this looks like though. The suitability of your tool depends on what it looks like.

    Please, always include screenshots in open source projects that are aesthetic in nature.

      I came to say the same thing, a screenshot is all I want to see before diving deeper.

      Yeah, I am also confused they didn’t include a screenshot (or photo in this case). It’s the first thing you’ll want to see for such a project.

      Thank you for posting this. It never ceases to amaze me how many open source GUI projects forget screenshots.

      I assume it doesn't look very good if they didn't want to show it off.

    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!

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

        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…

        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?

              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.

            • ksidisnidjsdj 2 hours ago
              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?

            • duskwuff 2 hours ago
              Not the case with a third-party display either.
          • carlosjobim 1 hour ago
            The newest design of MacBooks with the notch have the top corners of the display rounded.
            • ksidisnidjsdj 1 hour ago
              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.

            • duskwuff 1 hour ago
              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.
              • frizlab 1 hour ago
                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!
                • carlosjobim 1 hour ago
                  They are hardware.

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

      > 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.

      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?

        And to be honest? It’s really annoying indeed.
      • locao 1 hour ago
        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.
        • JoshTriplett 35 minutes ago
          Exactly. AI wrote this way because humans wrote this way. Just as humans used em-dashes long before AI was a thing.
      • Finnucane 58 minutes ago
        If AI does this, it's because it's ingested the last 25 years of bad internet headlines. Written allegedly by humans.

    I have no idea what this is fixing.

    > Note: This does not change the rounded corners of individual app windows. It only restores the straight silhouette at the edges of your display.

    My display does not have rounded corners. I am on macOS Tahoe using external monitors. I know that newer macbooks have rounded display corners, but those are rounded at the hardware level afaik, those corner pixels simply don't exist. And besides that, the medium article linked in the repo specifically talks about external monitors. Does anyone have an example of what this program is actually meant to fix?

    EDIT: I downloaded and compiled it myself to see. All it does is add a black border around your whole screen. Here is a screenshot: https://i.imgur.com/7XWAwxz.jpeg

    Again, I don't have rounded corners on my display in the first place, but if I did I suppose this would hide them. At the cost of losing the whole edge of my display, lol. I don't see why anyone would actually use this, especially since it cuts off half the menu bar.

    This has reminded me that in System 7, the code for the window was a system resource (resource forks contained all sorts of code, icons, text dictionaries etc). Anyhow, if you dropped an updated window resource into your system with the correct resource id, you could change this default behaviour. A friend of mine wrote a round window for a clock app, and made a copy with resedit in the system, and a reboot later, all windows were round.

    It was a very flexible and hackable system, very fragile, and no security whatsoever, but lots of fun!

    I'm assuming it wasn't the creator that posted this here, and I'm also assuming that the OP has managed to get this working. So @guessmyname can you please post a screenshot of the "fix" in use?

    A screenshot is the bare minimum for things like this.

    I think this project is best described by one of my favorite quotes from Top Gear: “an ingenious solution to a problem that should never have existed in the first place”.

    Thank you for the work but if you include an image of the problem why would you not include an image of the solution?

    A screenshot of the «after» would clear up a lot of confusion
