Can anyone hint me? I tried to run the cross-compiled app in MacOS x. x86_64 / widget - Cocoa. Do I understand correctly that the problem seems to be because of TrayIcon or Main menu? Everything is fine on other platforms
Code: [Select]

apparently the private API _setMenuOwner was removed from macOS.

What's your version?

ok, so the problem is with Handles used (within LCL internally).
LCLCocoa is acting pretty carelessly in this case, yet I'd anticipate that the issue might be with the code itself.

The question: how do you assign PopupMenu property for TTrayIcon control?

Renat.Su, just a heads up.

 I found TrayIcon leaked memory on both Carbon and Cocoa when I tried to use it some months ago. Might be a bit hard to detect if you are running a cross compiled binary so be careful.

So, standard method for assigning... But I found But I found one questionable code part in FormShow event
Code: [Select]
  if FOnCreate then
  begin
.......
    TryIcn.Icon:=Application.Icon; // Can be in this line mistake?
.......
    FOnCreate:=False;
  end;
I will try to compile with the commented line

Thank you for valuable nuance!

So, the problem was in that line in the implementation of the OnShow event of the main form.
Code: Pascal  [Select]
  1.  //   TryIcn.Icon:=Application.Icon;
  2. // Caused an error in Mac OS
Thank you all for advice!

The line shouldn't cause an error on macOS.

Could you please update cocoa widgetset to the latest revision and try again?

I'm using the latest stable version Lazarus/FPC. Do you mean to download and install the trunk Lazarus/FPC?

I will add that the icon did not exist. It was supposed to come from the source folder, but it wasn't there. However in Linux it did not cause the failure.

Unfortunately, the term "stable" might not apply to Cocoa widgetset. Using trunk version for Cocoa is preferred

I will add that the icon did not exist. It was supposed to come from the source folder, but it wasn't there. However in Linux it did not cause the failure.
on Cocoa (and macOS) in general, the executable is not located in the source code. Instead it's located within a bundle (a special directory structure).
The image should be placed within the same bundle into a resource directory.
Thus the code that loads an image
Code: [Select]
  Icon.LoadFromFile('icon.png')
would not work for OSX (unless you change current directory to the resource directory of the bundle) .

Yet again,
Code: [Select]
TrayIcon.Icon := Application.Icon;
should work just fine. (and it does work fine for Cocoa trunk)

Renat.Su, I can confirm what skalogryz says, cocoa in the Trunk is heaps better than in 1.8 release. (And quite a bit of the improvement is due to skalogryz I suspect).

This thread has a simple recipe for downloading and starting up a trunk version on a system that already has a working 1.8 and it won't, in any way, interfere with your 1.8 install.
https://forum.lazarus.freepascal.org/index.php/topic,40883.30.html

If you read the whole thread, you will see it has become about an IDE problem in Trunk at present so you will need to build your app and then run it outside the IDE. Don't forget to make an application bundle.

Thanks! I'll try to check it out. Now it seems to have earned the tester when I removed the specified line. The problem is simply that I do not have MacOS, but there is a tester that sometimes checks the ability of the MacOS build
