Hi,

On macOS 26 beta (up to beta 6 actually), our app icon did not show up in menu bar anymore. We actually have a bundle structure that contain 2 executable:

myApp.app
  Contents
    MacOS
      myApp
      myApp_client 

Executable `myApp_client` was in charge of the generation of the tray icon (using QSystemTrayIcon), but this did not work anymore in macOS beta from 1 to 5. However, moving the generation of the tray icon into the main executable worked.

Since then, Apple released macOS 26 beta 6 and everything seems to work again as usual. But in the meantime, I was in chat with Apple support, and they pointed out the root cause of the issue might be Qt bypassing call to `NSApplicationMain`. You can find the discussion with Apple support engineers here: https://developer.apple.com/forums/thread/794920.

Not sure if it's a bug or if this is even useful, but I just wanted to let you guys know about it.

Regards
