I have used the Mac M1 and M4.
Developing OpenGL projects on machines running macOS 15.2 and 13.6.
Call the OpenGL library functions of Mac.
glTexImage2D
If you use GL_LUMINANCE, GL_LUMINANCE_ALPHA, GL_ALPHA these three textures, you will get an error gl 500.
It makes me unable to draw normally on Mac.
What's the reason for this? Don't they support it?

I have a CoreImage pipeline and one of my steps is to rotate my image about the origin (bottom left corner) and then translate it. I'm not seeing the behaviour I'm expecting, and I think my problem is in how I'm combining these two steps.
As an example, I start with an identity transform
(lldb) po transform333
▿ CGAffineTransform
- a : 1.0
- b : 0.0
- c : 0.0
- d : 1.0
- tx : 0.0
- ty : 0.0
I then rotate 1.57 radians (approx. 90 degrees, CCW)
transform333 = transform333.rotated(by: 1.57)
- a : 0.0007963267107332633
- b : 0.9999996829318346
- c : -0.9999996829318346
- d : 0.0007963267107332633
- tx : 0.0
- ty : 0.0
I understand the current contents of the transform.
But then I translate by 10, 10:
(lldb) po transform333.translatedBy(x: 10, y: 10)
- a : 0.0007963267107332633
- b : 0.9999996829318346
- c : -0.9999996829318346
- d : 0.0007963267107332633
- tx : -9.992033562211013
- ty : 10.007960096425679
I was expecting tx and ty to be 10 and 10.
I have noticed that when I reverse the order of these operations, the transform contents look correct. So I'll most likely just perform the steps in what feels to me like the incorrect order.
Is anyone willing/able to point me to an explanation of why the steps I'm performing are giving me these results?
thanks,
mike
Hola. At this point, I'm at my wit's end because I've tried EVERYTHING just to be able to play a single game on my Mac, but the new update makes it impossible.
So I'm just gonna ask for one game: I've been trying to play Stardew Valley, modded with SMAPI, for a week now. Despite playing the game with mods for almost 2 years, OS is refusing to open the game because SMAPI "contains malware". I tried reinstalling the mod, but no dice. It just automatically deletes the terminal and blocks the game from opening.
You can imagine my frustration because the mod has been 100% safe for 2 years. No option to "Open Anyway" in Security Settings, either. I have no say in this. I've tried code signing it in Terminal (three times). Also no dice. Followed these two forums.

NOTHING. Please tell me there's a way to override this??? Just let me install malware on my computer!😭

Hello all... is there a way to close a contour if you have found say two points on each side top "extension"? see image attached. So in end desire a trapezoid type shape. Code example would be very appreciated. thank you :) Think I have it as a CGPath. So a way to edit a CGPath, or close the top from a top left to a top right point?
Does anyone know why the following call fails?
CGPDFOperatorTableSetCallback(operatorTable, "ID", &callback);
The PDF specification seems to indicate that ID is an operator?
BTW what is the proper topic/subtopic for questions about Quartz? Wasn't sure what topic on the new forums to post this under.
After many former OS and Xcode updates, my Game Controller Swift code generates a "DIS-CONNECTED" MESSAGE.

Hi,
The metal-cpp distribution appears to only contain headers for Foundation and Quartzcore. The LearnMetalCPP download [1] provides a ZIP with an metal-cpp-extensions directory containing AppKit.hpp and MetalKit.hpp headers. First question: Are these headers distributed anywhere else more publicly? Without these headers only the renderer can be fully written in C++ as far as I can tell, i.e. no complete C++ NSApplication. Second question: Will these headers, if needed, be maintained (e.g. updated and/or extended) by Apple along side metal-cpp?

Thank you and regards.
I am trying to simulate a paste command and it seems to not want to paste. It worked at one point with the same code and now is causing issues.
My code looks like this:
` func simulatePaste() {
guard let source = CGEventSource(stateID: .hidSystemState) else {
print("Failed to create event source")
return
}
let keyDown = CGEvent(keyboardEventSource: source, virtualKey: CGKeyCode(9), keyDown: true)
let keyUp = CGEvent(keyboardEventSource: source, virtualKey: CGKeyCode(9), keyDown: false)
keyDown?.flags = .maskCommand
keyUp?.flags = .maskCommand
keyDown?.post(tap: .cgAnnotatedSessionEventTap)
keyUp?.post(tap: .cgAnnotatedSessionEventTap)
print("Simulated Cmd + V")
}
I know that there is some issues around permissions and so in my Info.plist I have this:
<string>NSApplication</string>
<key>NSAppleEventsUsageDescription</key>
<string>This app requires permission to send keyboard input for pasting from the clipboard.</string>
I have also disabled sandbox. It does ask me if I want to give the app permissions but after approving it, it still doesn't paste.
We as a team of engineers work on an app intended to visualize medical images. The type of situations where the app is used involves time critical decision making for acute clinical conditions. Stability of the app and performance are of utmost importance and can directly help timely treatment action. The app we are developing uses multiple libraries and tools like vtk, webgl, opengl, webkit, gl-matrix etc.
The problem specifically can be described as follows, it has been observed that when 3D volume is rendered in the app and we try to rotate the volume the rotation is slow, unresposive and laggy. Specifically, we have noticed that iOS 18.1 the volume rotation is much smoother as compared to latest iOS 18.2. Eariler, we have faced somewhat similar issue with iOS 17 but it got improved in iOS 18.1. This performance regression is affecting the user experience in our healthcare application.
We have taken reference from the cornerstone.js code and you can reproduce the issue using the following example: https://www.cornerstonejs.org/live-examples/volumeviewport3d
Steps to Reproduce:
Load the above mentioned test example on an iPhone running version 18.2 using safari.
Perform volume rendering using the provided dataset.
Measure the time taken by volume for each rotate or drag action.
Repeat the same steps on an iPhone running version 18.1 for comparison.
Additional Information:
Device Model Tested:
iPhone12, iPhone13, iPhone14
iOS Version With Issue:
18.2
18.3(Beta)
I would appreciate any insights or suggestions on how to address this performance regression. If additional information is needed, please let me know.
Thank you.
, it is after update to Xcode 14.3:
[default] CGSWindowShmemCreateWithPort failed on port 0
Issue Summary:
In our Flutter application, we utilize Tencent's TRTC API for voice and video communication. While the broadcast functionality operates correctly on Android, it fails to respond on iOS devices. Attempting to initiate a broadcast results in no action, and long-pressing the broadcast button does not reveal the broadcast extension.
Steps to Reproduce:
Add Broadcast Upload Extension:
In Xcode, navigate to File > New > Target.
Select Broadcast Upload Extension and add it to the project.
2. Build the Project:
Attempt to build the project.
Encounter the error: "Cycle inside Runner; building could produce unreliable results."
3. Resolve Build Cycle Error:
Go to the project’s Build Phases.
Locate the Embed App Extensions phase.
Move Embed App Extensions just below Copy Bundle Resources.
Ensure the Copy only when installing option is selected.
Rebuild the project; the cycle error is resolved.
4.Test Broadcast Functionality:
Install the app on an iOS device.
Tap the broadcast button; observe no response.
Long-press the broadcast button in the top right hand scroll down menu; the broadcast extension is not listed.
5. Isolate the Issue:
Create a new Flutter project.
Repeat the above steps to add the broadcast upload extension.
The issue persists: broadcast functionality remains unresponsive on iOS.
I searched the Metal Shading Language Specification Version 3.0 document, however I cannot see any function for inverting a matrix. Is there really no function in Metal for inverting a matrix?
I often need to this in linear equations and have so far resorted to writing the necessary function each time, most of the time just copy-and-pasting code.
inverse exists in SIMD and GLSL, so why not in Metal? It seems so unexpected that this function does not exist that I am almost certain I have just overlooked something obvious. I even tried 1 / M, to no avail.
Hey folks,
I have a legacy game that is running OpenGL ES - and it no longer works on the simulators that are running Apple Silicon, ie iPhone 15 Pro, or the 13" iPads. And yes, i'm also running on Apple Silicon (M1 Max).
The apps work fine on the actual devices, but the simulator crashes on any glDrawElements with a stack that looks like the following:
I have not yet seen an announcement about this not working but i've seen mention in other apps of stopping to support GL (https://github.com/maplibre/maplibre-native/issues/2351)
Can anyone shed some light? I'm obviously going to try to fix it, or find a recent sample app from which to start to see what might be up. Or move to metal, but i hadn't bargained for that level of effort atm ;)
Any suggestions appreciated!
How to create a beautiful fire animation using Swift?
Which API is better to use?
Our application is trying to read all resolutions of an external monitor. We have observed that, for the external monitor there is a mismatch in resolution list in our application and the resolution list in system settings. We are using the apple API "CGDisplayCopyAllDisplayModes" to read the resolutions.
I am trying to use Broadcast upload extension but Broadcast picker starts countdown and stops (swiftUI).
Steps i followed.
added BroadcastUploadExtension as target
same app group for for main app and extension
added packages using SPM
i seems the extension functions are not getting triggered, i check using UIScreen.main.isCaptured also which always comes as false.
i tried Using Logs which never Appeared.
Hi, I've got a Swift Framework with a bunch of Metal files. Currently users have to manually include a Metal Lib in their bundle provided separately, to use the Swift Package.
First question; Is there a way to make a Metal Lib target in a Swift Package, and just include the .metal files? (without a binary asset)
Second question; If not, Swift 5.3 has resource support, how would you recommend to bundle a Metal Lib in a Swift Package?
Hey there,
I tried to install GPTK again, since I had to reinstall the OS for irrelevant reasons. But every time I try to install the tool kit, it gives me theError: apple/apple/game-porting-toolkit 1.1 did not build error. Before that error occired, I had the Openssl error, which I fixed with the rbenv version of openssl. Is there any way to fix this error? Down bellow you'll find the full error message it gave me. The specs for my Mac are (if they are helpful in any way): M1 Pro MBP 14" with 16GB Ram and 512GB SSD.
Thanks!

Like many folks here, I've recently attempted to build Apple's Game Porting Toolkit on my machine and ran into compiler errors, but instead of going the usual route of downloading the prebuilt package (kindly provided by GCenX), I decided to see if I could force it to build (since it was obviously buildable at some point). Down below is the list of things I had to do to make it work.
Disclaimer: There are several dirty hacks I had to attempt to force the system to do what I needed. Use at your own risk.
Don't forget to run all brew commands from a Rosetta prompt:
arch -x86_64 zsh
Install openssl
This one is easy. Just run
brew tap rbenv/tap
brew install rbenv/tap/openssl@1.1
Install Command Line Tools 15.1
This specific version is required since newer versions come with the linker that is not compatible with the custom compiler (game-porting-toolkit-compiler) that GPTK is using. However, by default 15.1 tools won't install on Sequoia since the installer complains that macOS version is too new. Obviously, Apple has their reasons to not allow this, but all we need is a compiler which should be mostly indifferent to the OS version.
To trick the installer, we need to change OS requirement of the installer package. You can do it in four easy steps:
Copy Command Line Tools.pkg from the mounted Command_Line_Tools_for_Xcode_15.1.dmg to some other directory.
Expand the installer package:
pkgutil --expand "Command Line Tools.pkg" CLT
You might be prompted to install Command Line Tools when you call pkgutil, just install any version.
Go to the newly created CLT folder and edit the Distribution file (it may appear as executable but it's just an xml). You would want to change allowed-os-versions to something greater than 15. Removing this section altogether might also work.
When done, re-wrap the package:
pkgutil --flatten CLT "Command Line Tools 2.pkg"
Congratulations, now you should be able to install 15.1 tools on your OS! If you had to install newer Command Line Tools for pkgutil, delete them before installing 15.1:
sudo rm -rf /Library/Developer/CommandLineTools
Next step is to make Homebrew accept the outdated 15.1 tools, as by default it'll complain that they're outdated or corrupted. To shut it up, open
/usr/local/Homebrew/Library/Homebrew/extend/os/Mac/diagnostic.rb
and remove references to check_if_supported_sdk_available from a couple of fatal build check collections.
Note - by default, Homebrew will auto-update on any invocation, which will overwrite any changes you've made to its internals. To disable this behavior, before running any brew commands in the terminal, run
export HOMEBREW_NO_AUTO_UPDATE=1
After these manipulations, Homebrew might still complain about outdated Command Line Tools, but it won't be a fatal error anymore.
Finally, we need to downgrade MinGW to 11.0.1, since the latest version spits out compiler errors when compiling Wine. Unfortunately, Homebrew does a bad job tracking versions of MinGW, so there is no automatic way to do it. Instead, you have to manually download and install old MinGW 11.0.1 formula from the Homebrew git repository. I used the commit from Sep 16, 2023:
https://github.com/Homebrew/homebrew-core/blob/b95f4f9491394af667943bd92b081046ba3406f2/Formula/m/mingw-w64.rb
Download the file above, save it in your current working directory, and then run
brew install ./mingw-w64.rb
If you had a newer version of MinGW already installed from the previous build attempts, you can unlink it before installing the one above:
brew unlink mingw-w64
With Command Line Tools 15.1 and MinGW 11.0.1 you should now be able to build GPTK without errors:
brew -v install apple/apple/game-porting-toolkit
In the end, steps above worked for me, although more things could break in the future. I'm leaving the instructions here just to show that it's still possible to build GPTK manually instead of relying on third parties, but with all the hoops I had to jump through I can't really recommend it.
I have an app that uses GameController to read the inputs of a connected JoyCon. However, the controller also interacts with the OS.
For example, when I press the Home button on the controller, it brings me to the home of my Vision Pro.
Is it possible to disable this interaction while still being able to read the controller inputs inside my app?
