I want to get MacOS Version from Objective-C build for iOS Apps to run on Apple Silicon Mac. Because AppStore In-App Purchase on Apple Silicon Mac had issues on MacOS version 13.0 and was fixed at version 13.3.1. I need to know the exact version of the MacOS to prevent users from buying In-App Purchases. I found that I can get iOS version that the app is emulating on and assume MacOS version from iOS version. But I think it's not 100% guaranteed way, because no documentation says anything about it. Is there a way to get MacOS Version in iOS Apps running on Apple Silicon Mac?

Helpppp. I installed Krita from the Appstore, it works. Then install ai_diffusion and I got : xcrun: error: cannot be used within an App Sandbox. Can anybody help me? Thanks.

Hello, I have an iPad app that users are running on their M1 / M2 MacBooks thanks to the "Designed for iPad" feature. Some of them reported to me that the pressed keyboard keys were not recognized. According to my source code, it seems that my custom views (that are set as firstResponder) do not get pressesBegan events. While I could not reproduce this specific problem on my M1 Macbook, I found a strange problem that may be related. My view also supports interaction with game controllers. I found that the emulated controller (which is using the keyboard, when the controller emulation feature of the Designed for iPad app is set to On) has some problems. The valueChangedHandler of the GCExtendedGamepad from the GCGameController is only fired if the app is compiled with the "Requires full screen" option set to On. If Requires full screen is unchecked in XCode, the Emulated Controller is still present in the list of game controllers, but no button callbacks are triggered. Note that a real game controller connected via USB will work correctly no matter how Requires full screen is set. Could there be a focus bug of the keyboard not sending events when the app is not a full screen app (resizable on mac, and multitask on iPad)? Or is there something I can change to avoid this problem? I'm lost.

Our apps can currently be installed on Apple Silicon Macs via the iPad app on Mac feature (“Designed for iPad”). Now we are working on “proper” (universal) Catalyst-based Mac apps that will be available on the Mac App Store. How does the transition work for users that currently have the iPad version installed? Will they automatically update to the Mac Catalyst app once it’s available, or do they need to re-install the app from the Mac App Store?

Hello all, I am wondering if anyone can help me with writing a script that fully uninstalls an app with one click or can point me to a script already written please? So that when I click the script it uninstalls the app and leaves nothing behind. So when I click finder and use the search function with the name of the app, then click add and then name matches (input name of app) then click add and select system files are included, nothing comes up as the script has completely removed it from my system. I am Using Mac Mini M2 Pro 16gb ram and macOS Sonoma. Thank you

Hi, Reading the copyFromBuffer documentation states that on macOS, sourceOffset, destinationOffset, and size "needs to be a multiple of 4, but can be any value in iOS and tvOS". However, I have noticed that, at least on my M2 Max, this limitation does not seem to exist as there are no warnings and the copy works correctly regardless of the offset value. I'm curious to know if this is something that should still be avoided. Is the multiple of 4 limitation reserved for non Apple Silicon devices and that note can be ignored for Apple Silicon? I ask because I am a contributor to Metal.jl, and recently noticed that our tests pass even when copying using copyWithBuffer with offsets and sizes that are not multiples of 4. If that coul cause issues/correctness problems, we would need to fix that. Thank you. Christian

I use to testing iOS app directly on my M1 Mac mini, without needing to plug in an iPhone. After updated to XCode 15.4, this option is gone.

Recently I started getting emails from AppStoreConnect when I submit new builds The email states: ITMS-90863: Macs with Apple silicon support issue - The app links with libraries that aren’t present in macOS: /usr/lib/swift/libswiftCloudKit.dylib I can run this app on apple silicon from TestFlight or directly from Xcode and it runs just fine including all iCloud functions. This app has been using iCloud for several years now. So my question is: Should I just ignore the email or do I need to change something to bring this app into compliance?

Hi All, Finder is caching the old application name and not showing the new application. I am deploying my iPad app to M1 Mac by generating a package file. In the newer version of this application, I have changed my application name and deployed the application from backend to user machines. Eventhough application is deployed successfully, the application name still remains the old. I went through the forum and tried the reset the finder cache and launcher service caches, but still the new application name is not coming. But when I uninstall and reinstall the application it is showing the new application name. Can someone suggest a way to reset this using script, as we are deploying the application from backend, we dont have direct access to the client machines Thanks Ranga

When rendering gradient of luma values you can clearly see that the monitor output from Apple Silicon GPU has lifted/curved blacks (values 0-31 out of 1024 in 10-bit output). Any idea what is going on and how to remediate? It looks like some kind of compensation/calibration for the screen panel response, but it is baked into output regardless of what kind of monitor (or non-monitor) is connected. The same rendering on Intel architecture produces correct linear gradation. We have tried M1, M2, M3 and they all seem to be affected.

Hello, I have an iOS app that is recording audio that is working fine on iPads/iPhones. It asks for microphone permission and after that recording works. I installed the same app on my M3 MacBook via TestFlight since iPad apps are supposed to work without a change that way. The app starts fine and everything, but it never asks for Microphone permission, so I can't record. Do I need to do something to make this happen (this is not macCatalyst, its running the arm64 iPhone binary on macOS) thanks

I am using XCode on my Mac Book Pro M1 and trying to run the iOS app being developed on my iPad (5th generation, 12.9 inch) The devices are connected through USB-C cable. I have enabled developer mode on my iPad, trusted the M1 device, the developer, and the app. However the following appears on the iPad when trying to launch the app: Unable to Verify App An internet connection is required to verify trust of developer "Apple Development: ...". This app will not be available until verified This seems to be an issue with M1 specifically, as other people seem to have this problem, and the application successfully runs on other iOS devices

Before Apple Silicon was a thing, I published a separate version of my iOS app for macOS. I'm no longer able to maintain this version, so I would like users to be able to use the iPadOS version of my app on Apple Silicon. Unfortunately I can't make it available through Prices & Availablity, because it says: "Once your macOS version has been approved, your iOS app will no longer be available to Mac users." (translated from the German user interface) How do I remove the previous version and publish the iPadOS version to the mac app store?

Hello, When I build an XCode project with the Apple Silicon chip, I have some issues. The project contains Pods and Swift Packages. I could not run the application at all and always got the following error: Could not find module '***' for target 'x86_64-apple-ios-simulator'; found: arm64, arm64-apple-ios-simulator, at: *** I try to resolve this issue. Always embed swift standard libraries = YES Build Active Architure Only = YES UIRequiredDeviceCapabilities = armv7 Excluded Architectures > Debug > Any iOS Simulator SDK arm64 add Open Using Rosetta Excluded Architectures > Debug > Any iOS Simulator SDK arm64 remove However, issue always come to me. :( Do you have any solution for this problem ? Thank you by advance !

Ventura 13.2.1 M1 Sonoma 14.2.1 M2 In my app I have a signal handler. When testing it with null-dereference I see that in previous MacOs versions like Monterey 12.0 x86 the signal handler is called. However, on my Silicon Ventura/Sonoma machines its not called. Tried with SIP enabled and disabled So I created a binary with code: #include <iostream> int main() { int *ptr = nullptr; std::cout << *ptr; // Dereference null pointer return 0; } Compiled it with: g++ null.cpp -o null.bin And executed it with and without sudo. The app indeed crashes because of the null dereference (and core dump is created when SIP disabled). However, no signal is recived. I am able to prove it with DTrace . DTrace script: #pragma D option quiet proc:::signal-send { @[execname, stringof(args[1]->pr_fname), args[2]] = count(); } END { printf("%20s %20s %12s %s\n", "SENDER", "RECIPIENT", "SIG", "COUNT"); printa("%20s %20s %12d %@d\n", @); } Here is the output. In the left terminal I executed the binary. In the right terminal the script output. On top of DTrace I created and MacOS endpoint-security app and subscribed to ES_EVENT_TYPE_NOTIFY_SIGNAL. Same there, no signal. Did anything change with signals on M1/M2 MacOS 13.0 ?

After enabling the signal alternative stack using sigaltstack, the thread stack region size comes to be 128 MB. The stack region size is only 8 MB without enabling the signal alternative stack. (get by calling the mach_vm_region_recurse function) It only happens on macOS 14 or later, and M series silicon. The growth of the stack region size results in a too-large minidump file when we generate a crash report using Google's crashpad library. Could anybody tell me why the size has increased so much? And is there a way to work around it?

I am using UDP communication in a app. Here is what i do, Initialises a UDP broadcast connection object. Bind it with a port to listen Receives the IP &amp; Port from the UDP connection to connect further with TCP connection. After updating Xcode 15.3, It works until the iPad is connected with mac in debug mode. When i create build to test remotely, it stops receiving IP &amp; Port from UDP connection. Here is how i concluded this is Xcode issue, I tried to debug this issue with Xcode 15.2 and it works as expected with debug and after creating build also. Any help / suggestion would be appreciated.
