Hello, I recently submitted an enhancement request through Feedback Assistant requesting official native macOS support for Genshin Impact. Feedback ID: FB25106712 I am an Apple Developer Beta tester, a Mac user, and a passionate gamer. I regularly test macOS developer beta releases and provide feedback on performance, stability, compatibility, and the overall system experience. I also genuinely enjoy testing games on Mac and seeing what Apple Silicon is capable of. I have personally tested games such as Wuthering Waves, Cyberpunk 2077, and Minecraft on Mac, and my experience with them has been extremely positive. Wuthering Waves in particular runs very smoothly and seamlessly on my Mac. These experiences have made me feel that the capability for excellent gaming on Apple Silicon is already there. The larger limitation, in my experience, is the availability of native support. As a major HoYoverse fan, Genshin Impact is one of the games I would most like to experience and test natively on macOS. At present, Mac users have to rely on third-party workarounds such as PlayCover, compatibility solutions, or cloud gaming rather than having an officially supported native client. I would really like to see Apple work with HoYoverse to bring Genshin Impact natively to macOS, properly optimized for Apple Silicon and Metal. I would also be very happy to test such a release across macOS versions and provide detailed feedback on performance, graphics, stability, thermals, controller support, and the overall gaming experience. Could this enhancement request be brought to the attention of the appropriate Apple team, or is there an appropriate channel through which I can provide further feedback regarding this request? Thank you for your time.

The CGSetDisplayTransferByTable() is not working on the latest round of Mac hardware, namely the MacBook Neo (external display), MacBook M5 Pro (both built-in and external display) and possibly the M5 Max. All tested apps (BetterDisplay, MonitorControl, f.lux, Lunar) exhibit the very issue both in macOS Tahoe 26.3 and macOS Tahoe 26.4 RC. Tested on multiple Macs and installations on the MacBook Neo and MacBook M5 Pro. This issue breaks several display related macOS apps. Way to reproduce the issue using an affected app: Install the app BetterDisplay (https://betterdisplay.pro) Launch the app, open the app menu, choose Image Adjustments and try to adjust colors. Adjustments take no effect Way to reproduce the issue programmatically: Attempt to use the affected macOS API feature: https://developer.apple.com/documentation/coregraphics/cgsetdisplaytransferbytable(::::_:) Here are the FB numbers: FB22273730 (Filed this one as a developer on an unaffected MBP M3 Max) FB22273782 (Filed from an affected MBP M5 Pro running 26.4 RC, with debug info attached)

I’m testing RealityKit cloth for garment-like cloth over an authored human-shaped triangle-mesh collider. The issue also occurs with a static collider, so it does not appear to depend on character animation.. Contact is stable and runs interactively, but I cannot achieve close surface contact without sacrificing robustness. The cloth mid-surface remains visibly several millimetres from the authored collider, especially around curved or narrow areas such as the head, arms, and hands. Transparent rendering of visualMesh confirms this is not just render thickness. Reducing ClothMeshShape.bias reduces the gap, but eventually causes interpenetration around difficult geometry. Increasing it prevents penetration but makes the cloth visibly float. I’ve also checked scale, winding, normals, reasonably even triangles, timestep, and solver iterations. I want to avoid inflating the collider or adding anatomical proxy shapes. Is bias the only physical-clearance control, or does RealityKit apply an additional contact radius derived from simulation-mesh resolution? Is local conforming refinement the recommended way to achieve roughly 1–2 mm clearance while retaining robust real-time contact? Are there any specific topology requirements beyond evenly sized triangles? I can provide a minimal reproduction and screenshots if helpful although not sure I can share screenshots here?

Hello everyone!! 😊🤗 I'm starting to learn development for Apple platforms and I'd like to ask for some guidance on how to get started. My goal is to gradually develop my own video game using Xcode and Reality Composer Pro. The idea is to create an educational game with 3D environments and elements, so I also want to learn programming, experience design, and 3D content creation as I progress ⭐️ At the moment, I don't have much money to afford to hire developers to mentor me or take expensive courses 😔( My mother is sick and all our resources and budget are focused on her and her treatment. ) but I do have something I think is very important: a strong desire to learn, time, and the willingness to study and practice. I don't expect someone else to do the project for me; I want to learn how to build it myself. My main question is: where should I begin? I already have experience playing Swift Playgrounds, and I find it fascinating 🤩 but I'm looking for the next step: I'd like to know what Apple concepts, courses, documentation, or resources you would recommend I study first to learn how to use Xcode and Reality Composer Pro correctly, especially with the Apple Developer tutorials. Which videos specifically do you recommend I study? If anyone started in a similar way or has experience developing apps or games with these tools, I would greatly appreciate any advice on a learning path. Thank you so much for taking the time to read this and for any guidance you can give me! You truly don't know what this means to me. Thank you so much. 🙏🚀

Hello everyone, I’m developing Echoes of the Broken Sun, an original science-fantasy real-time strategy game being built for macOS and Apple Silicon in Unreal Engine. The project began as a personal experiment: I wanted to see how far I could take a complete game by providing the design, architecture, requirements, creative direction, and acceptance criteria while using AI extensively for implementation. I am not treating generated code as automatically correct. Every feature still has to be reviewed, tested, integrated, and proven against the intended design. The project has now progressed beyond an initial concept and into a functioning prototype, and I would like to connect with developers, designers, artists, testers, and other contributors who may be interested in helping shape it. Echoes of the Broken Sun is not intended to be a traditional high-actions-per-minute RTS where success primarily depends on keyboard speed. The goal is to reward strategic judgment, battlefield awareness, logistics, positioning, intelligence, resource denial, and decisions that can affect the remainder of a match or campaign. The central strategic mechanic is the Future Well, a contested resource that forces players to choose between immediate power and long-term possibility. A player can harvest it for resources, preserve it for future advantages, or reshape it to temporarily alter the battlefield. Those decisions are intended to create meaningful tradeoffs rather than a single optimal build order. The game currently includes three asymmetric factions: Meridian, which emphasizes control, organization, and technological precision Kharuun, which relies on mobility, pressure, and aggressive adaptation Hollow Choir, which uses disruption, sacrifice, and unconventional battlefield effects The current prototype includes a deterministic C++ simulation, an RTS camera and selection system, construction and production, logistics limits, AI opponents, local skirmish support, campaign progression, save and restore functionality, victory conditions, faction-specific units and structures, and early multiplayer networking work. There is still substantial work ahead. The user interface, accessibility, balance, visual presentation, audio, performance optimization, multiplayer security, Apple signing and notarization, clean-machine testing, and overall player experience all need further development. I would especially like to hear from people with experience or interest in: Unreal Engine and C++ gameplay development macOS, Apple Silicon, Metal, Xcode, signing, and notarization Multiplayer architecture, networking, testing, and security RTS design, faction balance, AI, and campaign development UI, accessibility, 3D art, animation, visual effects, sound, or music Playtesting, technical review, documentation, or build validation This is not a finished commercial release or a formal job posting. It is a serious passion project with a public repository, documented architecture, test evidence, known limitations, and an active development roadmap. Contributions do not have to be large. Code review, testing, design feedback, performance analysis, or help with a specific Apple-platform issue would all be valuable. Project page: https://redxking.github.io/echoes-of-the-broken-sun/ GitHub repository: https://github.com/redxking/echoes-of-the-broken-sun Anyone interested in the concept is welcome to reply here or reach out through GitHub. Please mention the area you are interested in and whether you would like to contribute, test, review, or simply follow the project. Thank you for taking a look. Angelis Pseftis

Hello Apple! We've got offline shader compilation from HLSL -> Metallib using DXC -> SPIR-V -> metal.exe. This works okay for the most part, but it requires the creation of intermediate files to pass to/from the metal.exe process and we've had some issues with metal.exe sometimes not launching (probably our fault). Then we noticed Metal Shader Converter (MSC) exists and has a DLL - this looks way better since there's no need to launch processes or store intermediate files. However, upon trying to replace metal.exe with it I quickly ran into rampant heap corruption. I was surprised because the docs claim this: Each thread in your program needs to create its own instance of IRCompiler to avoid race conditions. But once I start calling IRCompilerAllocCompileAndLink in parallel all hell breaks loose, whether or not each thread has its own IRCompiler. I figured I must be doing something wrong, so I removed my attempt and compiled DXC locally with the MSC integration and encountered the exact same heap corruption. So I'm inclined to think the library isn't actually thread safe, but I'm wondering if there's something I'm missing? I tried all 3 versions of MSC just in case it was a problem with 3.0, but I got the same result each time. The only way to make it work was to surround compilation with a mutex, which makes its use pointless in our case.

Hello, I use a Gigabyte M32U monitor with my Mac mini. After updating to macOS Golden Gate 27 Release 3, I started experiencing an issue with my external display. Whenever I turn my monitor off and then turn it back on, the refresh rate automatically changes from 144Hz to 98Hz, and the 144Hz option disappears from the display settings. However, if I unplug the display cable and plug it back in, the monitor is detected again and the 144Hz option returns, allowing me to select it normally. This issue only started after updating to macOS Golden Gate 27 Release 3. Before the update, the monitor consistently worked at 144Hz without any problems. Could you please investigate this issue? Thank you.

Hello everyone, I am posting this to determine whether other iPad Pro M4 users are experiencing the same issue. Device: iPad Pro 11-inch (M4) Original Apple charger Tested on multiple iPadOS versions, stebal and beta including 26.2, 26.3, 26.4, 26.5.2 Games Tested: BGMI PUBG Mobile Global Call of Duty: Mobile Fortnite Issue: Despite using one of Apple's most powerful tablets, I continue to experience gaming performance problems. The issues include: FPS drops during long gaming sessions. Frame pacing inconsistencies. Reduced responsiveness during intense fights. Inconsistent hit registration and spray accuracy after extended play. Performance sometimes changes when gaming while charging with the original Apple charger. I have tested multiple iPadOS versions and multiple game updates over several months, but the issue has never been completely resolved. Interestingly, iPadOS feels more consistent for me than some previous versions, but the overall gaming experience is still not what I would expect from the M4 hardware. I have also noticed that many other iPad Pro M4 users have reported similar concerns on Reddit, Apple Communities, and other gaming forums. Questions: Are other iPad Pro M4 users experiencing the same FPS drops and gameplay inconsistencies? Has anyone found a reliable solution? Is Apple aware of these gaming performance issues on the M4 iPad Pro? Is this an iPadOS optimization issue, a GPU scheduling issue, or something related to game optimization? I hope Apple and game developers investigate this further because the M4 hardware should be capable of delivering a consistently excellent gaming experience. Thank you.

I have a very basic usdz file from this repo I call loadTextures() after loading the usdz via MDLAsset. Inspecting the MDLTexture object I can tell it is assigning a colorspace of linear rgb instead of srgb although the image file in the usdz is srgb. This causes the textures to ultimately render as over saturated. In the code I later convert the MDLTexture to MTLTexture via MTKTextureLoader but if I set the srgb option it seems to ignore it. This significantly impacts the usefulness of Model I/O if it can't load a simple usdz texture correctly. Am I missing something? Thanks!

Hey all — I’ve been building out my first set of Game Center Achievements for a game I’m working on, and I’ve run into something odd with the image quality. The specs say to upload icons at 512x512 or 1024x1024@2x. I’ve been uploading 1024x1024 PNGs (without explicitly naming them “@2x” since there’s only one upload slot), assuming that Game Center would just handle the scaling automatically — kind of like how a lot of things are getting more streamlined across platforms lately. But in testing, the icons are showing up a bit blurry, especially in the Game Center interface. It’s not horrible, but it’s definitely softer than I expected — more like low-res than Retina. All my test devices (outside the Simulator) are running iOS 26, so I’m also wondering if this might be a beta-related display bug? Has anyone else run into this? Curious if I’m missing a best practice here, or if I really do need to ensure I’m uploading it with the @2x suffix, or maybe something else entirely? Thanks!

As a game studio with real business commitments, we depend on a predictable App Review process. Every month, we publish updates, run user acquisition campaigns, and test new ideas; that’s how our business operates. It’s not optional. We have obligations to our partners, our marketing budgets are committed in advance, and our entire monthly rhythm depends on getting builds out on schedule. Right now, Apple’s App Review is making that impossible. For the past 30 days, we’ve been stuck in a rejection loop on a single submission. Here’s what the cycle looks like: • Apple rejects our build with vague, generic feedback that doesn’t actually identify what’s wrong. • We investigate every possible scenario that could conceivably match their description, fix what we believe is the issue, and resubmit, usually within three hours. • Then we wait. And wait. Each review of the resubmission takes more than ten days. Read that again: we respond in 3 hours, they respond in 2 weeks. This isn’t a one-off. It’s been three full cycles now, and we still don’t have clarity on what they actually want changed. The rejection notes are so shallow that we’re forced to guess; patch a plausible cause, ship it, and hope. It honestly feels like reviews are being triaged by AI models that aren’t ready for the job yet: surface-level pattern matching, no real engagement with the build, no specifics we can act on. Meanwhile, the cost is real: • UA campaigns we’ve already committed budget to are bleeding out. • Partner deliverables are slipping. • Our team’s monthly release rhythm — the engine of how we operate as a business — is broken. • We’re paying engineers to play guessing games with a reviewer who won’t tell us what’s wrong. We’ve escalated everywhere we can. Contact forms, appeals, developer support, every channel Apple offers. Nothing has moved. We love the platform. We want to keep shipping great games on iOS. But Apple needs to understand that App Review isn’t just a gatekeeping checkbox, it’s a load-bearing piece of every developer’s business operation. When a single rejection cycle eats 10+ days and the feedback isn’t actionable, you’re not protecting users. You’re breaking the businesses building for your platform. Two things need to change, urgently: 1. Restore meaningful, specific rejection feedback. Tell us exactly what’s wrong, with reproduction steps. If a human reviewer can’t be specific, an AI definitely shouldn’t be making the call. 2. Prioritize resubmissions on an in-flight review. A 10-day turnaround on a fix to a rejection you issued, three hours earlier, is indefensible. These should jump the queue, not start at the back. If anyone at Apple is reading this: we’re trying to work with you. Please help us help you. Want me to tighten it, make it angrier, soften it, or pull out the bullet lists so it reads as straight prose for the forum?

My game has been stuck in “Waiting for Review” since March 18 (2 months now). I already received confirmation that my expedited review request was accepted (although it was only accepted about a week ago, despite requesting it much earlier), but the app still has not entered active review. Developer Support keeps confirming that the app is in queue and that it will be “reviewed shortly,” but I have heard that four times already, with no concrete action or explanation provided. Has anyone experienced something similar recently or found a solution?

I'm updating our app to support metal 4, but the metal 4 types don't seem to get recognized when targeting simulator. Is it known if metal 4 will be supported in the near future, or am I setting up the app wrong?

I'm new to graphics and game design and I just wanted to know if a compute pipeline could be as efficient as a render pipeline for rasterization and an explanation on how and why. Also is it possible to manually perform rasterization with a render pipeline as in manipulate individual pixel data in a metal texture yourself but do it with a render pipeline?

I am new to RealityKit and Metal and I am building a RealityKit app that renders a procedural LowLevelMesh road. But the left and right side of the road is a complete green terrain mesh object and it doesn't look great. What I want is to add some rocks, tall trees and dence bushes (or weed) to make it look like the player is in the woods. But when I add many of those objects then the performance drains. What is the best approach to fill background empty spaces in the scene?

Explanation Currently, D3DMetal’s GPU synchronization approach introduces significant compute overhead on the CPU. This specifically affects D3D12 games that use modern rendering pipelines on Apple Silicon. Specifically, I’ve tested Death Stranding 2 On the Beach for how it handles its rendering. And the results are extreme: frame times are suffering from a 42% decrease from synchronization. Although there are obviously other effects at play, such as the overhead introduced by Rosetta and Wine, both of them don’t introduce as much overhead as D3DMetal. This issue isn’t just specific to Death Stranding 2 On the Beach; most games running through D3DMetal suffer from this. Most games still seem to force synchronization to ~30 ms to reach the 30 fps amount. But it could be better with better synchronization, such as how DXMT handles it. Instead of doubling the work, it allows Metal to single-handedly track resource dependencies internally. This is in part due to the unfortunate bad mapping of D3D12 calls onto shared logic between D3D11 and D3D12.
