There is no way GLM-5.2 would have been able to backport WebKit.
Are you sure 🙂

Are you sure 🙂
Yes, I trust my experience actually working with these things much more than synthetic benchmarks which the providers can game. Admittedly I haven't used GLM 5.2 since it came out yesterday, but my experience with GLM 5.1 is that it's far worse than the benchmarks would suggest.

I do need to try out the OpenAI models again at some point, they used to be clearly worse than Claude, but I've heard GPT-5.5 is much better. But I'm not going to do that for WebKit, because the consensus on Hacker News is that Opus 4.8 is still better at long-running tasks, and this is basically the longest task.

Edit: It's also text only, which means it can't test Safari.

Okay, I think this is far enough where I'm comfortable letting other people play around with it, if they want to. Everything gets copied into the associated folders in /System/Library. Please remember:
  1. You must make a Time Machine backup first!
  2. AquaProxy is effectively required.
  3. You must use Safari 7, not Safari 9.
    • If you don't know where to get Safari 7, there's a working copy in the Applications folder of the Mavericks installer DMG which should work. (Just copy it out, no special extraction necessary.)
    • ^ However, if you previously installed Safari 9, then you will also have a Safari 9-specific WebKit framework on your system under StagedFrameworks. It is theoretically possible this may interfere with something.
    • Just to be clear, if you've never installed a Safari update, please keep it that way. It makes things simpler and matches my own testing VM.
  4. This will update the web views used in (almost) every app, not just Safari!
    • Accordingly, it also has the potential to cause issues in any app which uses a web view.
    • The web views in 32 bit apps will be unchanged. This is intentional; modern WebKit is 64-bit only.
  5. I do not recommend using this as a daily driver. For the moment, it's a fun toy. Hopefully it can eventually become more than that.
Crashes or bugs which can be consistently reproduced every time are very helpful—I will feed those directly back to the agent. Feel free to test beyond only Safari. This includes small polish-level details; I care a lot about those.

Transient problems which cannot be consistently reproduced are, frankly, not very helpful at this time. However, I will personally enjoy hearing about your experience.

Known issues:
  • You cannot scroll in Reader Mode.
  • Web Inspector toolbar looks wrong.
  • If you open the App Store app and right click, you will see a context menu which should not exist.

Okay, that's got to be the problem: StagedFrameworks is the updated Safari 9 WebKit. I guess Safari 7 also looks there if present? I don't really understand this mechanism and I have not experimented with it yet.

Depending on how much you're willing to mess with this system (make sure you're in a position to undo it), you could try deleting StagedFrameworks, or you could try replacing the WebKit in StagedFrameworks too.

Eventually, if this backport becomes good enough for real use, I'll need to make a full Safari 9 downgrade script.

If it helps, I had Mail open before WebKit installation on a message that may have included JavaScript.

@_sudo11 Thanks for all the testing, very helpful! A heads up that I am very unlikely to have any updates before next Tuesday at the earliest because I'm approaching my usage limit for the week.

@_sudo11 Thanks for all the testing, very helpful! A heads up that I am very unlikely to have any updates before next Tuesday at the earliest because I'm approaching my usage limit for the week.
Thank you so much for all this work and all the money you are willing to pour into this!
 
It appears that I have destroyed my machine, any app made by Apple that I attempt to open tells me that this app cannot be opened because of a problem, this occured after attempting to open Xcode.

Oh no! Restoring stock WebKit doesn't fix it?

You may need to fully restore from Time Machine!
 
So last week, Claude completely destroyed the Virtual Machine it was running in. I don't know how precisely, but most apps including Finder wouldn't open, and even using SSH I couldn't modify or write most files.

I'm not particularly surprised by this. Claude was running with full sudo access and explicit instructions to take initiative and experiment. But, a word of warning to anyone who wants to give Claude carte blanche outside of an isolated VM...

And you want it backporting a web browser you're going to use?

😳

...this is, like, not the same thing at all. The AI was explicitly and forcefully told to experiment and try stuff, and left running for ages, which meant it had ample chances to screw up. The problem with messing with your system is that if you screw up, you often can't undo it. I myself, working without an AI, always do this sort of work inside of Virtual Machines first. I also put zero effort into trying to fix the VM, so it may well have been something simple, but the entire point of using a VM is that it can be thrown away.

Anyway, I really can't be more clear that this is a toy and experiment. I'm pretty optimistic it will go somewhere, but at some point I'm going to have to dig in and do more steering. Likely soon, now that school is out. The entire premise of this project was "I'm off teaching at school all day, my computer is sitting idle at home as is this Claude subscription I'm paying for but only use on evenings and weekends, what can I have the system work on in the meantime?"

I just reinstalled mavericks, all broken apps function perfectly. I will start testing in a VM from now on.

Alright, glad you're up and running again, shame we don't know what broke though! Many Apple apps don't link WebKit at all and should not have broken like that.

The point of this project isn't as a rock solid reliable web browser that will take whatever we throw at it, that is Momiji's job. I see this project as more of a toy or an experiment to see what we can make, if it manifests as a reliable replacement, great! If not, too bad.
 
Over the past week, I've spent a lot of time actively working on this project—much more than I would have liked, really. Claude still wrote all the code, but (most of the time) I was actually watching it, telling it what to do and fix in broad strokes.

WebKit is now built with a modern macOS SDK, something I should have been doing from the start. It's also using GStreamer for video playback and WebRTC, mirroring what WebKitGTK does on Linux.

Safari is much more stable now—not fully stable, but usable. I've also tested Apple Mail, TextMate, Dash, and every other app with a WebView I can think of.

I have officially replaced vanilla WebKit on my own computer, outside of any virtual machine. The catch is that I don't have Safari installed. I don't like to keep more than one web browser installed at a time—I find I get confused about which app I'm in—and the backport still has issues with some specific websites which work fine in Momiji. Since I do everything on Mavericks, I really need 100% website compatibility.

But it's really awesome to have e.g. working QuickLook previews!

If you use this, please add issues to Github moving forward: https://github.com/Wowfunhappy/WebKit/issues
