    Papercuts like this are why I moved away from macOS.

    I will say, I don't love the use of LLMs to write these bug reports. It's probably fine if reviewed, but at least review for things like "worked on macOS 25", which obviously didn't exist. If that wasn't caught, how sure are you that the rest of the report is accurate? We all want the bugs fixed, but people are going to start throwing out the obviously LLM written reports rather than have to validate each claim, since the author probably didn't.

      I'm used to papercuts on every OS, but at least with a Linux box I can roll it back. Usually it's as easy as picking the previous boot menu entry (with NixOS, the whole system rolls back that way). I find macOS acceptable enough for my laptop, but I'm doing most of my real work in Linux containers anyway.

      Yes, for the time being the final report should probably come from us (but endless opportunity along the way to clarify thinking and understand industry standard terms).

      Using LLMs for any kind of writing is unethical, with the narrow exception of translation. If you didn't take the time to compose your words thoughtfully then you aren't owed the time to read them.

        There is a huge difference between using an llm and just blindly dumping it's output on someone verbatim.

        I think it's fine to have an llm write a first or second draft of something, then go through and reword most of it to be in your own voice.

          at this point I really think its better to read broken english than have to read some clanker slop. it immediately makes me want to just ignore whatever text i'm reading, its just a waste of time

            I do wonder, we had pretty good (by some measure of good) machine translations before LLMs. Even better, the artifacts in the old models were easily recognized as machine translation errors, and what was better, the mistranslation artifacts broke spectacularly, sometimes you could even see the source in the translation and your brain could guess the intended meaning through the error.

            With LLMs this is less clear, you don’t get the old school artifacts, instead you get hallucinations, and very subtle errors that completely alter the meaning while leaving the sentence intact enough that your reader might not know this is a machine translation error.

        > If you didn't take the time to compose your words thoughtfully then you aren't owed the time to read them.

        Apply this argument to code, to art, to law, to medicine.

        It fails spectacularly.

        Blaming the tool for the failure of the person is how you get outrageous arguments that photography cant be art, that use of photoshop makes it not art...

        Do you blame the hammer or the nail gun when the house falls down, or is it the fault of the person who built it?

        If you dont know what you're doing, it isnt the tools fault.

    Still wishing for the day apple is split into the hardware and the software company. I want their silicon, but I will never use their (arguably terrible) operating system. If I can't run my own kernel and kernel modules then it's a device that I don't own. Firmware is alright in some cases, but my laptop next to me is running core boot just to prove a point.
    • t-sauer 46 minutes ago
      But you can run your own kernel on Macs, no? Isn‘t driver support the issue?
      • vbezhenar 9 minutes ago
        Maybe Apple Hardware would write Linux drivers to sell their hardware for servers. Intel contributes to Linux kernel. AMD contributes to Linux kernel. Nvidia contributes to Linux kernel. A lot of hardware manufacturers support Linux to some extent. It's no longer reverse-engineered wild west.

      (arguably terrible) operating system

      macOS has made some arguably poor design choices, but it makes it hard to take someone seriously when they state the whole OS is terrible.

    • whalesalad 37 minutes ago
      macOS is not perfect but I don't think anyone could seriously argue that it is terrible.

    A couple iOS versions ago, Apple broke self-signed certificates... crippling mobile development by preventing the use of HTTPS to communicate with a local server.

    It makes you wonder why they were messing around in these areas at all at this point.

      Because they can and sheeple will still line up around the block at their next iphone launch.

    I run a setup like that on my (outdated) Yosemite machine to provide multiple private TLDs for local deployment/development needs.

    I set that up in like 2014? Even back then it was known already that the quick /etc/resolver way was the deprecated way to do things. So I guess they finally killed that feature off?

    The proper (more awkward) way is to use scutil directly (which then stores the settings in some binary plist somewhere, I assume).

    Maybe try this and see if it still works afterwards?

  • ProllyInfamous 25 minutes ago
    I am not familiar with dnsmasq at all (is this machine-local?), but absolutely love my PiHole hardware — you can even create rules which intercept hard-coded-IP DNS request and/or httpsDNS. You can also hard-code/intercept .TLD to local service IPs.

    Programs like LittleSnitch never really seem like "enough" for me, because the computer has to boot before DNS filtering comes online. It also has the design error (IMHO) of pre-resolving IP addresses before clicking Accept/Deny(all).

    A great blockrule for your personal firewalls would be to ban (at top level) icloud.com, apple.com, &c; system updates can then be performed manually using guides like <http://www.mrmacintosh.com>. Of course: this breaks everything (in exactly the way I prefer to compute).

      This works great (and I use it) internally but when you want things like your docker domains to work when you're on the go, it's annoying.

      I have setup a VM running DNS on my laptop before ...

  • JimDabell 18 minutes ago
    *.localhost works out of the box doesn’t it? You don’t need dnsmasq at all to have multiple hostnames pointing to 127.0.0.1.

    Bit off-topic. I mostly use Linux and I'm of the opinion that it's miles better than Windows, but I don't fully understand why people say MacOS looks bad?

    Ignoring the current Tahoe mess, MacOS felt relatively polished. I'm purely talking about UX here, as the OS is evidently buggy. The most popular Gnome themes are a re-impl of MacOS, so I can't be the only one.

    • vbezhenar 2 minutes ago
      It's incredibly bloated. I don't want AI engine in my OS. I don't want Spotlight in my OS. I don't want my OS to load CPU for 10 minutes after boot for who knows what. I don't want my OS to ship with Chess app and lots of other irrelevant software. I don't want my OS to ship with Music app and bother me with subscription offers. I don't want my OS to ship with iCloud app.

      They also do strange choices regarding shipped software. For example they ship ancient bash 3, apparently because they hate GPLv3 or something like that. I like GPLv3 and this choice makes macos user-hostile.

    • kace91 29 minutes ago
      I'm with you, pre Tahoe I've never had an issue with iOS aesthetically, other than lack of customisation.

      Then again I never understood the trend to remember fondly windows 98 and those kind of interfaces, maybe it's generational.

      It’s selection bias; the people who complain are the most visible online. Especially HN.
    • nslsm 29 minutes ago
      There’s no “Tahoe mess”. I’ve used it since 26.0 and it’s good. Different indeed, but good. People love complaining.
      • hbn 6 minutes ago
        There's very valid reasons to have issues with Tahoe's changes. The dock being liquid glass is fine. But curving the windows to look like iPad apps, and not even adjusting the grab target appropriately for resizing the window is bad. Getting rid of the title bar so it's not clear where you can grab a window is bad. Apple Music hiding the volume slider behind another click is bad.

        I'm glad that it's working well for you, but from the moment some users with M-series SoCs report laggy animations, something somewhere has to be wrong.
  • hk1337 38 minutes ago
    I've been using macOS since OS X Tiger and I wasn't aware of this feature.
  • neilsharma425 42 minutes ago
    Has anyone found a working workaround yet? I use dnsmasq for .local dev routing and held off updating after seeing this but curious if there is a viable path forward short of waiting for Apple to patch it.
    • kenny_r 4 minutes ago
      What I'd suggest is using lvh.me, which always resolves to localhost, as do all it's subdomains. If you need a specific IP you can use nip.io.

      If you want valid certs you can generate them with mkcert and add them to your system trust store.

    • cortesoft 36 minutes ago
      Wouldn’t the workaround just be to have your local dns server enable recursive lookups, and point all your DNS queries to it?
    • mkagenius 39 minutes ago
      holding off update seems like reasonable step till the patch comes. I also run a .local for apple containers though not docker.

    Thank you for the heads up.

    If you have ScreenTime turned on. Port :8080 is occupied and your ubuntu apt-get in a docker build gets hash mismatch because they obviously modified packets. Let alone I am having another issue of unable to delete a private key in Keychain Access.

    The whole macOS thing is amateur

    • 1718627440 41 minutes ago
      Why does macOS use ports above 1024 by default? There is a reason it is reserved to be used by OS services.
    • delduca 44 minutes ago
      Port 5000 is also ocupied on macOS.

    Before others jump in: I already use Linux (and used to run FreeBSD as my desktop operating system).

      Thanks for sharing your report, it's frustrating to see things like this break in minor patch updates. Small tip for GitHub Gist: set the file format to markdown (give it a .md extension) so that the markdown will be rendered and won't require horizontal scrolling :)

    It also seemingly broke removing Safari cookies on a per website basis, something I often used to stop Google's scummy tracking across all their services if you just want to sign into YouTube.

      Firefox + Google Container extension.

      Why use Apple's browser when they don't actually care about your privacy?
