PureDarwin

[Vali @DaylonValorant]

capture card le shit, but here's this.
first is real hardware on an Orange Pi Zero 4
second is Indium with pdmtl as a backend, using the same translation layer as the OPi Zero 4.

[Vali @DaylonValorant]

flaky SD card fixes first, then real hardware.
progress is slow, but here's loginwindow, with no skipping.
entire setup flow worked as normal, with severe rendering artifacts.

[Vali @DaylonValorant]

still got a lot of issues, but bare metal test is copying still.
ImpureDarwin is in a somewhat decent state, but man, this is UNGODLY slow at a blazing fast 0.6 FPS

[Vali @DaylonValorant]

so here's what's new in ImpureDarwin.
for the first time, and many fixes later, HID input works, and I can actually progress through the Setup Assistant

[Vali @DaylonValorant]

code signing.
yay!

[Vali @DaylonValorant]

getting better.
taking a break from ImpureDarwin, and working through my changes on several worktrees to commit it.

[PureDarwin @puredarwin]

@ththtvibyha Not exactly.
It's macOS 26.6.2 (Virtual Mac)'s IPSW repackaged with PureDarwin's tooling, then PureDarwin's kernel

[PureDarwin @puredarwin]

this is on a RPi5, via KVM.
bare metal once I get my hands on hardware.
too broke for a good quality ARM board

[PureDarwin @puredarwin]

@ssighv unmodified*

[PureDarwin @puredarwin]

holy shit

[PureDarwin @puredarwin]

@ssighv yup.
translating AIR -> LLVM IR, then JITed down to aarch64.
userland is entirely modified besides the daemon handling AIR -> LLVM

[PureDarwin @puredarwin]

an exert from Discord

[PureDarwin @puredarwin]

@vgs499p nor can I.
will open source after cleanup and fixes.
most of the changes are OSS, but I wanted to be the first to get a screenshot out.

arm64e on arm64 looking better
still a wip

[PureDarwin @puredarwin]

@piecaruso97 @Acelogic_ It's an in-kernel object directly placed on the framebuffer

[PureDarwin @puredarwin]

Huge thanks to Maika (`farwestsanctuary`), latita (`latitud`), onizukas, and 1nf (`execat`) on Discord.

Maika lent me a MacBook Pro to test on, and updated it specifically so I could test on a VM.

onizukas lent me their MacBook Air for a few hours

latita ran a bunch of probes so I could avoid guessing at things for weeks, same with 1nf

And a special thanks to cleverca22 at libre rpi, they lent me a 24/7 Raspberry Pi 5 (8Gb)

[PureDarwin @puredarwin]

arm64e on arm64 rendering
mildly messed up
wip

[PureDarwin @puredarwin]

Deeply messed up but here's Language Chooser begining to render it's menu bar. AIR has a stroke in my JIT daemon.

More to come

[PureDarwin @puredarwin]

@chrisprice We also plan on getting Metal in PureDarwin eventually. This project is to learn how Apple officially handles Metal and what a GPU driver looks like for Metal
