It’s so good to have Stacktrace by @johnsundell and @_inside back after two years. Seeing it show up in my Overcast feed genuinely made my heart skip a beat. I’ve honestly missed it quite a lot 🥹 @stacktracepod

@_inside interesting. now try it with real iOS, and not the modified private cloud compute image. like with my full Apple Silicon emulation project, Inferno, for example.

Since a recent firmware included components for a virtual iPhone, I decided to see if I could boot one up. This is a virtualized iPhone 16 running iOS 26.2. Don't get too excited, as this required a lot of IPSW patches and SpringBoard crashes when I swipe up in the setup screen.

@newlooklurker @shitpost9000 @aboutzeph It’s both. The low-tech alternative would be for the watch to display a numeric code that the user has to type on their phone. Since the phone has a camera, you can use a QR Code, but a normal QR Code is not as cool as this 😄

@kai_h @shitpost9000 @QxD5e @aboutzeph The data itself is also changing, but I wouldn’t call it an animation, as it’s just changing on every frame. That high frequency noise probably helps the algorithm on the other device to extract it more easily.

@shitpost9000 @QxD5e @aboutzeph Interesting - although I now wonder if it's a static code overlaid on top of the pre-built animation, or if the data is also animated? The patent from Apple says that they also animate the data component, but now I'm questioning everything.

I'm too lazy for budgeting apps. I generally only want to know if numbers go up or numbers go down over a period of time, so, introducing Bread Count =D breadcount.app

@JoeBlack2k It’s really fast on my M2 Max MacBook Pro. This is native virtualization, not emulation. I gave the VM 8gb of ram

@_inside What kinda speed does it have? Being a VM? I guess it’s M series Mac only? With passtrough cpu or is it emulated? Can you specify the amount of ram it gets?

@xelahot I’m hoping I won’t have to. This is all supported out of the box by Apple’s native virtualization, and they’ll likely make this available for security research in the near future.

@_inside Do you plan on making this open source? It looks so much smoother than ChefKissInc/Inferno

@xelahot Pretty much anything since you can load a patched kernel, TXM, SPTM, iBoot, etc. Root fs and cryptexes are fully customizable as well.

@_inside That's so sick! I wonder what could be done what could not. Jailbreak that emulated iOS, Sideload apps to test without a test device, jailbreak research, etc.

surprise! got iOS 18.5 booting up to SpringBoard in my Apple Silicon emulator, Inferno, no proprietary components. it's the first ever open source emulator to run iOS 18. however not very stable due to memory corruption, we are working to resolve it, then it will go public. will be a big win for the OSS and iOS security research community.

@muvaff I don’t think it would be a part of Xcode, probably just a tool for security research.

@_inside Hmm maybe A/M processor difference🧐 We run iOS simulators at scale and network isolation has been a PITA. Do you see any signs of this being part of xcode?
