The problem is, I've a backlog of stuff that should be committed together with IOMFB, so I can't commit that part right now.
On the other hand, we just got Springboard running properly~~
I'm working on Multitouch stuff rn.

Hi,
we are making some progress on that, but I cant really make any estimation on when it will be usable.

@TrungNguyen1909 Can you commit it to another branch? It's been several months.

Did you read my comment? It says AMD iGPUs on macOS, meaning macOS hackintoshes. Don't know what Springboard has to do with it
I know this is unrelated to the thread itself, but I placed it as a comparison point for how slow this has been worked on. Our project had more RE than code involved as well.
Rephrased the original comment, I apologise for the confusion

Ahhh cool!
Someday we will be able to run iOS 15 apps on PC using this project š

Have you tried with gpu=0 boot argument? (source: Corellium) Basically this forces SpringBoard to do software rendering. I tested this argument on a physical device: UI lags as expected, Safari no longer exposes WebGL, so I guess you may find some luck here.

@khanhduytran0 ahh, I tried adding that, but SpringBoard is still crashing in CoreImage (-[CIContext init])

Can I have a look into ObjC error(?) and backtrace?
Also, maybe you could try these CoreImage-related environment variables: CI_ENABLE_METAL_GPU=0 CI_FORCE_SOFTWARE_GL=1 CI_USE_SW=1 (all of these are undocumented so Iām unsure what could change)

Hm, seems like it is forcing to use OpenGL anyway, even with +[CIContext contextWithCGContext:options:] and kCIContextUseSoftwareRenderer being set š¤

My test was done on iOS 12. I tried on iOS 14.3 but it turned out to ignore gpu=0. It appears that Apple took away CoreImage software rendering since iOS 13 (Corellium added GPU support at the same time)
I think it can be worked around by just hooking +[CIContext internalContextWithEAGLContext:options:] to return nil, hopefully making any calls to the context no-op.

It's been so long, me and @NyanCatTW1 have already single-handedly gotten hackintoshes with AMD integrated GPUs working on macOS Big Sur & published it already, in comparison.

Idk if I'm allowed to send that here, and uh, there's a lot of work to do so I haven't published it yet. Kidding, check my profile's pinned repositories. Do note it's still experimental, but it's relatively stable

Does this boot the Springboard, or is it just one of many drivers needed to get it working? Either way, nice work!
