Solved: Edit Scheme -> Build -> Overide Architecture -> "Universal" or "Use Target Settings".

Builds Settings -> All -> Architectures: “Standard Architectures (Apple Silicon, Intel) - $(ARCHS_STANDARD) for both Debug and Release Builds Settings -> All -> Build Active Architecture Only: “No” for both Debug and Release Reinstall MacOS 26.1, Xcode 26.2. Same result: no Universal, only one platform (Silicon or Intel, never both)

Typo error in title: Mac App not Map App No Universal for Mac App project with Tahoe

With NSOpenPanel opendir() work correctly but the user don't want to select files and folders each time the application is launched. So I save the files and folders URLs for the next time. But then opendir(the_saved_URL) fail. What is the way to make opendir(the_saved_URL) work correctly ?

Thank a lot for all precious reply.

No one except the: "No error handler for XPC error: Connection invalid" that happen when the application quit.

If you disable Visible At Launch, you get this log message. Yes This log message is bad. Surely Thus you need a different way to make your window not visible at launch. Yes

Thank you for the link. With os_log_error(OS_LOG_DEFAULT, ""); I was able to see that disable "Visible At Launch" in MainMenu.nib cause the "CGSWindowShmemCreateWithPort failed on port 0" log error. What can I do to make the window not visible at launch (other than close the window in awakeFromNib)? How to fix the second issue: "No error handler for XPC error: Connection invalid" The code don't use any communications (etnernet, wifi or bluetooth) call.

How to use: b libsystem_trace.dylib``_os_log_error_impl ?

Yes! The correct syntax is: and v8.8b, v8.8b, v10.8b On other hand do you know (I am just curious) why ARM does "and immediate" so restricted ? By example the assembler accept add x2,x1,#32 but reject and x2,x1,#22 Thank you very much.

So things have changed from previously? No except now I distribute within Xcode (I no longer use Transporter): To create a distribution-signed app using the Xcode app: [from "Export an app from Xcode" in your link "Creating distribution-signed code for macOS" ] 1- Select your app’s scheme. 2- Choose Product > Archive. 3- In the Archives organizer, select the archive created in step 2. 4- Click Distribute App. 5- Choose the appropriate distribution method. For example, to create a notarized app that you send directly to your customers, choose Direct Distribution. 6- Click Distribute. No issues no errors. Because earlier you were reporting an “App sandbox not enabled” error? No longer see this error. Is "App Store Version Release" must be set "Automatically release this version" ? What is the next step ? Thank you.
