My favorite part of this is the detour to ask for the IOUSBFamily src on IRC

Re: I ported Mac OS X to the Nintendo Wii
#92Not only is this an insanely cool project, the writeup is great. I was hooked the whole way through. I particularly love this part: > At this point, the system was trying to find a framebuffer driver so that the Mac OS X GUI could be shown. As indicated in the logs, WindowServer was not happy - to fix this, I’d need to write my own framebuffer driver . I'm surprised by how well abstracted MacOS is (was). The I/O Kit…
IOKit was actually built from the ground up for OS X! NeXT had a different driver model called DriverKit. I've never coded against either, but my understanding was they're pretty different beasts. (I could be wrong) That said, indeed, the abstraction layer here is delightful! I know that some NetBSD devs managed to get PPC Darwin running under a Mach/IOKit compatibility layer back in the day, up to running Xquartz on…
Funnily enough, there is a (different) DriverKit in macOS again now ;)

As I remember it, they were basically the same—but IOKit is C++ (with restrictions) because 3rd party developers didn't want to learn Objective-C. But that's a hazy, 20 year old memory.

"At some stage in the future we may be able to move IOKit over to a good programming language"

#94Wonder if it can happen on the Wii U
With the extra RAM, higher clock speed, and no need to waste CPU cycles converting YUV -> RGB framenbuffers - I bet it would be!

#95Congrats, great project and great writeup. That would have won MacHack back in the day. Now that the MacBook Neo has an A18, I wonder if you could get MacOS running on an iPhone? :)
Or better yet, an iPad!

There is a zero percent chance of that ever happening.

I almost think such projects are worth it just to immortalize comments like these. There's a whole psychology of wrongness that centers on declaring that not-quite-impossible things will definitely never happen, because it feels like principled skepticism.
That used to be my thing: wherever our ops manager declared something was impossible, I’d put my mind to proving her wrong. Even though we both knew she might declare something impossible prematurely to motivate me. My favorite was “it’s impossible to know which DB is failing from a stack trace”. I created STAIN (stack traces and instance names): a ruby library that would wrap an object in a viral proxy (all returns…
Well you're doing gods work as far as I'm concerned. Conflating difficulty in practice with impossibility in principle is, to my mind, a source of so much unnecessary cognitive error.

This solution’s COU cost can be significantly improved by using memory protection. You protect the frame buffer from writes. The first time it is written, you take a fault, and start refreshing every 60 Hz and leave it writeable. After some number of refreshes, you protect it again, the idea being is that the UI may now be quiescent. I do this in my Palm OS port for the same reason.

#100They are successfully porting Mac OS onto every kind of modern computer over at the hackintosh subreddit, and I can't understand why there is so little interest for this stuff in the "hacker" sphere.
Surely, it must be a better option than Linux if you want to get the most out of a PC computer? At least for 10 more years.
