Hi all, I'm working on migrating a legacy codebase to run natively on Apple Silicon macOS. The project builds and runs fine on Rosetta, but anytime I try to build it for Apple Silicon I get build errors from referencing CarbonAPI. Is it possible to resolve these issues and get CarbonAPI to build natively for Apple Silicon, or will I have to rewrite the offending pieces of code? Thanks!

I am trying to install Python from source according to the readme using: ./configure make <-- Error happens here make test sudo make altinstall However, I cannot complete the make command since it fails with: Undefined symbols for architecture arm64: "_libintl_bindtextdomain", referenced from: __locale_bindtextdomain in _localemodule.o "_libintl_dcgettext", referenced from: __locale_dcgettext in _localemodule.o "_libintl_dgettext", referenced from: __locale_dgettext in _localemodule.o "_libintl_gettext", referenced from: __locale_gettext in _localemodule.o "_libintl_setlocale", referenced from: __locale_setlocale in _localemodule.o __locale_localeconv in _localemodule.o "_libintl_textdomain", referenced from: __locale_textdomain in _localemodule.o ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [Programs/_freeze_module] Error 1 Looks like make is somehow using the wrong architecture. I just don't know why. Does anyone have an idea?

I have the higher end M1 Mac Studio, and I have had a lot of success with Metal pipelines. However, I tried to compile a compute pipeline that uses the bfloat type and it seems to have no idea what that is. Error: program_source:10:55: error: unknown type name 'bfloat'; did you mean 'float'? Is there an OS update that is necessary for this support?

Hi everyone, I'm trying to test some functionality of jax-metal and got this error.

I just recently saw a message in the Unity forums, by a Unity staff member, that Apple requires an Apple Silicon based Mac (M1, M2) in order to build apps for the Vision Pro glasses. This confused me since the simulator works just fine on my Intel Mac. Is there any official statement from Apple on this? It would be weird to buy a new Mac just because of this.

We use an in-house OpenGL app to provide the out-the-window visuals for our flight simulators. The app is cross platform, but until now the Mac version was only used by desktop researchers, not in our primary sim labs. Now we are attempting to replace some Windows boxes with Apple Studios. We can easily maintain high framerate, and visual quality is excellent, but we are finding the graphics have a bit of stutter during high yaw rates (which quickly forces new assets into view). I've eliminating unnecessary processes, tried raising my priority via pthread_set_qos_class_self_np() or thread_policy_set(), and reducing textures quality, all of which helped, but it didn't eliminate the problem. For background, we are using framebuffers, we have a very large texture database (90 GB), and the render code runs in the main thread (not a secondary thread). What might I be missing?

I am in the process of developing a matrix-vector multiplication kernel. While conducting performance evaluations, I've noticed that on M1/M1 Pro/M1 Max, the kernel demonstrates an impressive memory bandwidth utilization of around 90%. However, when executed on the M1 Ultra/M2 Ultra, this figure drops to approximately 65%. My suspicion is that this discrepancy is attributed to the dual-die architecture of the M1 Ultra/M2 Ultra. It's plausible that the necessary data might be stored within the L2 cache of the alternate die. Could you kindly provide any insights or recommendations for mitigating the occurrence of on-die L2 cache misses on the Ultra chips? Additionally, I would greatly appreciate any general advice aimed at enhancing memory load speeds on these particular chips.

It seems that Xcode Cloud currently only uses Intel machines for running the workflow jobs. When will Apple Silicon machines be available and supported?

I've been trying to get the bash/script version of DeepFaceLab to work with Apple Silicon Macs, but this was original a Windows project that even now has non-existent support for MacOs/Apple Silicon. I am thinking of converting everything into a native macOS app using Swift, specifically optimized for Apple Silicon GPUs. Here's what I got from ChatGPT. Any help/advice on how to do this would be greatly appreciated. I don't have any Swift programming experience, but I have experience with some coding and can generally figure things out. I know that this is probably not feasible for a single individual with little programming experience, but I wanted to throw this out there to see what others think. Thank you Here's a high-level overview of the steps involved in porting DeepFaceLab to Swift with a graphical UI: Understand DeepFaceLab: Thoroughly study the DeepFaceLab project, its Python scripts, and the overall architecture to grasp its functionalities and dependencies. Choose a Swift Framework: Decide on the UI framework you want to use for the macOS app. SwiftUI is Apple's latest UI framework that works across all Apple platforms, including macOS. Alternatively, you can use AppKit for a more traditional approach. Rewrite Python to Swift: Convert the Python code from DeepFaceLab into Swift. You'll need to rewrite all the image processing, deep learning, and video manipulation code in Swift, potentially using third-party Swift libraries or native macOS frameworks. Deep Learning Integration: Replace the Python-based deep learning library used in DeepFaceLab with an appropriate Swift-compatible deep learning framework. TensorFlow and PyTorch both offer Swift APIs, but you may need to adapt the specific model implementation to Swift. Image Processing: Find equivalent Swift libraries or frameworks for image processing tasks used in DeepFaceLab. UI Development: Design and implement the graphical user interface using SwiftUI or AppKit. You'll need to create views, controls, and navigation elements to interact with the underlying Swift code. Integration: Connect the Swift code with the UI components, ensuring that actions in the GUI trigger the appropriate Swift functions and display results back to the user. Testing and Debugging: Rigorously test the Swift application and debug any issues that arise during the porting process. Optimization: Ensure that the Swift app performs efficiently and effectively on macOS devices.

We recently started working on getting an iOS app to work on Macs with Apple Silicon as a "Designed for iPhone" app and are having issues with speech synthesis. Specifically, voices retuned by AVSpeechSynthesisVoice.speechVoices() do not all work on the Mac. When we build an utterance and attempt to speak, the synthesizer falls back on a default voice and says some very odd text about voice parameters (that is not in the utterance speech text) before it does say the intended speech. Here is some sample code to setup the utterance and speak: func speak(_ text: String, _ settings: AppSettings) { let utterance = AVSpeechUtterance(string: text) if let voice = AVSpeechSynthesisVoice(identifier: settings.selectedVoiceIdentifier) { utterance.voice = voice print("speak: voice assigned \(voice.audioFileSettings)") } else { print("speak: voice error") } utterance.rate = settings.speechRate utterance.pitchMultiplier = settings.speechPitch do { let audioSession = AVAudioSession.sharedInstance() try audioSession.setCategory(.playback, mode: .default, options: .duckOthers) try audioSession.setActive(true, options: .notifyOthersOnDeactivation) self.synthesizer.speak(utterance) return } catch let error { print("speak: Error setting up AVAudioSession: \(error.localizedDescription)") } } When running the app on the Mac, this is the kind of error we get with "com.apple.eloquence.en-US.Rocko" as the selectedVoiceIdentifier: speak: voice assgined [:] 2023-05-29 18:00:14.245513-0700 A.I.[9244:240554] [aqme] AQMEIO_HAL.cpp:742 kAudioDevicePropertyMute returned err 2003332927 2023-05-29 18:00:14.410477-0700 A.I.[9244:240554] Could not retrieve voice [AVSpeechSynthesisProviderVoice 0x6000033794f0] Name: Rocko, Identifier: com.apple.eloquence.en-US.Rocko, Supported Languages ( "en-US" ), Age: 0, Gender: 0, Size: 0, Version: (null) 2023-05-29 18:00:14.412837-0700 A.I.[9244:240554] Could not retrieve voice [AVSpeechSynthesisProviderVoice 0x6000033794f0] Name: Rocko, Identifier: com.apple.eloquence.en-US.Rocko, Supported Languages ( "en-US" ), Age: 0, Gender: 0, Size: 0, Version: (null) 2023-05-29 18:00:14.413774-0700 A.I.[9244:240554] Could not retrieve voice [AVSpeechSynthesisProviderVoice 0x6000033794f0] Name: Rocko, Identifier: com.apple.eloquence.en-US.Rocko, Supported Languages ( "en-US" ), Age: 0, Gender: 0, Size: 0, Version: (null) 2023-05-29 18:00:14.414661-0700 A.I.[9244:240554] Could not retrieve voice [AVSpeechSynthesisProviderVoice 0x6000033794f0] Name: Rocko, Identifier: com.apple.eloquence.en-US.Rocko, Supported Languages ( "en-US" ), Age: 0, Gender: 0, Size: 0, Version: (null) 2023-05-29 18:00:14.415544-0700 A.I.[9244:240554] Could not retrieve voice [AVSpeechSynthesisProviderVoice 0x6000033794f0] Name: Rocko, Identifier: com.apple.eloquence.en-US.Rocko, Supported Languages ( "en-US" ), Age: 0, Gender: 0, Size: 0, Version: (null) 2023-05-29 18:00:14.416384-0700 A.I.[9244:240554] Could not retrieve voice [AVSpeechSynthesisProviderVoice 0x6000033794f0] Name: Rocko, Identifier: com.apple.eloquence.en-US.Rocko, Supported Languages ( "en-US" ), Age: 0, Gender: 0, Size: 0, Version: (null) 2023-05-29 18:00:14.416804-0700 A.I.[9244:240554] [AXTTSCommon] Audio Unit failed to start after 5 attempts. 2023-05-29 18:00:14.416974-0700 A.I.[9244:240554] [AXTTSCommon] VoiceProvider: Could not start synthesis for request SSML Length: 140, Voice: [AVSpeechSynthesisProviderVoice 0x6000033794f0] Name: Rocko, Identifier: com.apple.eloquence.en-US.Rocko, Supported Languages ( "en-US" ), Age: 0, Gender: 0, Size: 0, Version: (null), converted from tts request [TTSSpeechRequest 0x600002c29590] <speak><voice name="com.apple.eloquence.en-US.Rocko">How much wood would a woodchuck chuck if a wood chuck could chuck wood?</voice></speak> language: en-US footprint: premium rate: 0.500000 pitch: 1.000000 volume: 1.000000 2023-05-29 18:00:14.428421-0700 A.I.[9244:240360] [VOTSpeech] Failed to speak request with error: Error Domain=TTSErrorDomain Code=-4010 "(null)". Attempting to speak again with fallback identifier: com.apple.voice.compact.en-US.Samantha When we run AVSpeechSynthesisVoice.speechVoices(), the "com.apple.eloquence.en-US.Rocko" is absolutely in the list but fails to speak properly. Notice that the line: print("speak: voice assigned \(voice.audioFileSettings)") Shows: speak: voice assigned [:] The .audioFileSettings being empty seems to be a common factor for the voices that do not work properly on the Mac. For voices that do work, we see this kind of output and values in the .audioFileSettings: speak: voice assigned ["AVFormatIDKey": 1819304813, "AVLinearPCMBitDepthKey": 16, "AVLinearPCMIsBigEndianKey": 0, "AVLinearPCMIsFloatKey": 0, "AVSampleRateKey": 22050, "AVLinearPCMIsNonInterleaved": 0, "AVNumberOfChannelsKey": 1] So we added a function to check the .audioFileSettings for each voice returned by AVSpeechSynthesisVoice.speechVoices(): //The voices are set in init(): var voices = AVSpeechSynthesisVoice.speechVoices() ... func checkVoices() { DispatchQueue.global().async { [weak self] in guard let self = self else { return } let checkedVoices = self.voices.map { ($0.0, $0.0.audioFileSettings.count) } DispatchQueue.main.async { self.voices = checkedVoices } } } That looks simple enough, and does work to identify which voices have no data in their .audioFileSettings. But we have to run it asynchronously because on a real iPhone device, it takes more than 9 seconds and produces a tremendous amount of error spew to the console. 2023-06-02 10:56:59.805910-0700 A.I.[17186:910118] [catalog] Query for com.apple.MobileAsset.VoiceServices.VoiceResources failed: 2 2023-06-02 10:56:59.971435-0700 A.I.[17186:910118] [catalog] Query for com.apple.MobileAsset.VoiceServices.VoiceResources failed: 2 2023-06-02 10:57:00.122976-0700 A.I.[17186:910118] [catalog] Query for com.apple.MobileAsset.VoiceServices.VoiceResources failed: 2 2023-06-02 10:57:00.144430-0700 A.I.[17186:910116] [AXTTSCommon] MauiVocalizer: 11006 (Can't compile rule): regularExpression=\Oviedo(?=, (\x1b\\pause=\d+\\)?Florida)\b, message=unrecognized character follows \, characterPosition=1 2023-06-02 10:57:00.147993-0700 A.I.[17186:910116] [AXTTSCommon] MauiVocalizer: 16038 (Resource load failed): component=ttt/re, uri=, contentType=application/x-vocalizer-rettt+text, lhError=88602000 2023-06-02 10:57:00.148036-0700 A.I.[17186:910116] [AXTTSCommon] Error loading rules: 2147483648 ...

I've been working on an iOS project for the iPhone and would like to support running it on macOS computers with Apple Silicon. In the Targets / Supported Destinations we added "Mac (Designed for iPhone)" but experienced Thread 1: EXC_BAD_ACCESS crashes immediately when we tried to run it. We've isolated it down to Stepper UI elements in our view. Starting a new project and just trying to present a single Stepper in the ContentView, we get the same crash. Here is code that presents the issue: // ContentView.swift import SwiftUI struct ContentView: View { @State var someValue = 5 var body: some View { VStack { Stepper("Stepper", value: $someValue, in: 0...10) } } } When run from Xcode on an iOS device or the simulator, it runs fine. Trying to run it on the Mac, it crashes here: // Stepper_01App.swift import SwiftUI @main // <-- Thread 1: EXC_BAD_ACCESS (code=2, address=0x16a643f70) struct Stepper_01App: App { var body: some Scene { WindowGroup { ContentView() } } } Xcode 14.3 (14E222b), MacOS Ventura 13.3.1 (a), Mac mini M2. Target: Mac (Designed for iPhone) We have verified that the same code crashes on all the Apple Silicon Macs we have access to. Searching the Internet and Apple Developer forums I dont find other reports, so I kind of feel there must be some level of either user error or system/project misconfiguration going on? If any iOS app that used Steppers was just crashing when trying to run on a Mac, it seems like this would be a big deal. If anyone has input or can point out what we need to do differently, it would be appreciated!

For all my iOS projects only simulators running iOS 16.4 are listed as Run Destinations ... although I've installed the iOS 13 simulator and corresponding entries are listed under "Devices & Simulators". I've toggled "Show run destination" from "Automatic" to "Always" with no avail. Deployment target is e.g. iOS 13, and I'm running Xcode Version 14.3 (14E222b) on a 14" MBP with Apple Silicon. As a current bypass I'm booting up the simulator manually and install apps by "xcrun simctl install booted APP.app" to allow some basic testing, but that's no sustainable solution. Any help is much appreciated! Mattes

Users can run our apps on Macs with Apple Silicon via the "iPad Apps on Mac" feature. The apps use PHPhotoLibrary.requestAuthorization(for: .addOnly, handler: callback) to request write-only access to the user's Photo Library during image export. This works as intended on macOS, but a huge problem arises when the user denies access (by accident or intentionally) and later decides that they want us to add their image to Photos: There is no way to grant this permission again. In System Preferences → Privacy &amp;amp; Security → Photos, the app is just not listed – in fact, none of the "iPad Apps on Mac" apps appear here. Not even tccutil reset all my.bundle.id works. It just reports tccutil: Failed to reset all approval status for my.bundle.id. Uninstalling, restarting the Mac, and reinstalling the app also doesn't work. The system seems to remember the initial decision. Is this an oversight in the integration of those apps with macOS, or are we missing something fundamental here? Is there maybe a way to prompt the user again?

Hi. Sorry if this question has been answered in another post, if it has I can't find it. My device is MacBook Pro 16-inch, M1, 2021. So I tried to create a VM using this guide from Apple I followed the guide and used an image of debian. Everything worked fine until the machine appeared stuck at some point of the installation. I chose my languages then I had some other prompt asking me to install something but I can't remember precisely the step at which I thought it was freezed (I think it was the GNOME install) So because the machine was not responding for several minutes (I might have been too hurried) I quitted the process by simply clicking on the Quit button in the VM window. The problem is that from that point onward, I can't load any VM anymore. The build is successful in Xcode, the machine starts but immediately quits with this response from Xcode logs : Virtual machine successfully started. Guest did stop virtual machine. 2023-02-02 22:22:45.413600+0100 GUILinux[22984:380971] [client] No error handler for XPC error: Connection invalid I just can't understand why, I tried to delete and download the guide again but it doesn't work. I will add that it's my first time using Xcode and I might have missed something obivous.

Hi, I have an iPad app that has menus, like:  CommandGroup(replacing: .help) {                 Button("Help") { showHelp = true }                     .keyboardShortcut("/")  } They works fine in iPad and also if compiled to Mac Catalyst, but will crash on Apple Silicon Mac when selected the menu items with errors like: [General] -[_UIEditMenuInteractionMenuController propertyList]: unrecognized selector sent to instance 0x600000190540 I did not use storyboard and only use SwiftUI. Any suggestions? Note: of course the best solution is to compile to Mac Catalyst, but the app has some other issues when run in Mac Catalyst. So I can only release it as iPad app.

Hi All, I would like to know if there are any C APIs to control the Floating-Point Control Register (FPCR) on Apple Silicon? The ARM documentation does not show any C APIs for doing this. The only example code looks like VHDL, so I was wondering if any developers here knew of any. Thanks

I maintain a cross-platform client side network library for persistent TCP connections targeting Win32, Darwin and FreeBSD platforms. I recently upgraded to a Mac Studio w/ M1 Max (Ventura 13.1) from a late 2015 Intel Macbook Pro (Monterey 12.6.2) and I've encountered a discrepancy between the two. For secure TCP connections my lib uses WolfSSL across all platforms but also supports use of system provided Security libraries. On Darwin platforms this is SecureTransport. Yes I am aware SecureTransport is deprecated in favor of Network. I intend to attempt to integrate with Network later but for now my architecture dictates that I use similar C-style callbacks akin to WolfSSL, OpenSSL, MBedTLS etc. On the first call to SSLHandshake the SecureTransport write callback generates 151 bytes for my TLS 1.2 connection to example.com:443 on both platforms. However, while on Intel MBP I am able to continue with the full handshake I immediately receive 0 bytes with EOF. In Wireshark on the Intel MBP the 151 bytes are observed as a TLS 1.2 client hello while on M1 it is observed as an SSL continuation message and that is the last message observed.

My device is MacBook Pro 13-inch, M1, 2020 Use source code provided by article https://developer.apple.com/documentation/virtualization/running_gui_linux_in_a_virtual_machine_on_a_mac When installing Debian, Fedora or Ubuntu, installation process can stuck at any point and cause the installation failed. Even if it is lucky enough to pass the installation phase, stuck could still happen at any time when the virtual machine is started. It seems that there is some low level error that cause the Linux kernel panic, while during this process error seems to be accumulated--it starts with some user level application in Linux starts to behave weirdly, such as sudo does not authenticate a valid user, apt can not run properly, then Linux kernel panic. Sometimes it behaves like the VM get stuck where it is not sure what happened inside it. I can't provide more detail as it happens randomly and the phenomenon differs each time. While generally it appears to be an accumulated error and eventually the VM get stuck.

MacOS M1 machines can run iOS applications. We have an iOS application that runs a fullscreen metal game. The game can also run across all desktop platforms via Steam. In additional to Steam, we would like to make it available through the AppStore on MacOS. We'd like to utilise our iOS builds for this so that the Apple payment (micro-transactions) and sign-in processes can be reused. While the app runs on MacOS, it runs in a small iPad shaped window that cannot be resized. We do not want to add iPad multitasking support (portrait orientation is not viable), but would like the window on MacOS to be expandable to full screen. Currently there is an option to make it full screen, but the metal view (MTKView) delegate does not receive a drawableSizeWillChange event for this, meaning the new resolution of the window cannot be received. Is there another method of retrieving a window size change event in this context? What is the recommended way of enabling window resizing on MacOS but not iPad for a single iOS app?

I know as of macOS 11.1 it is now possible to run your iOS/iPadOS apps in fullscreen on silicon Macs. Though I couldn't find anything online of how to do this. How would I go about making my app compatible?
