psn_0_23787182 when running bundle

[circular]

I've asked someone to compile LazPaint on MacOS, but there was the following error when running the bundle (not when using the play button in Lazarus) :

Unknown command : psn_0_23787182

What can we do about it ?

ignore it, it's a random launch ParamStr, i got this -psn_0_1020153 now on my app, and this -psn_0_1032444 and so on.

Mac OS X sends it, I don't know what for.

Ok, got it. Thanks !

If you're using ParamStr to detect files passed to the app, that won't work with OS X. Here's how to do that:

Thanks.

[Yes - I know - ancient history, but I ran into the issue today and as I have more info...]

ProcessSerialNumber
Defines the unique identifier for an open process.

struct ProcessSerialNumber {
   unsigned long highLongOfPSN;
      unsigned long lowLongOfPSN;
      };
      typedef struct ProcessSerialNumber ProcessSerialNumber;
      typedef ProcessSerialNumber * ProcessSerialNumberPtr;
      Field Descriptions
      highLongOfPSN
      The high-order long integer of the process serial number.

      lowLongOfPSN
      The low-order long integer of the process serial number.

      Discussion
      You should not make any assumptions about the meaning of the bits in a process serial number. To compare two process serial numbers, you should use the function SameProcess.

      You can obtain a process serial number in one of the following ways:

      Process serial numbers are returned by the functions LaunchApplication, GetCurrentProcess, and GetFrontProcess.

      Some high-level events return process serial numbers.

I was trying to open a test text file (text.xyz) with my SimpleEditor application by double-clicking on the file which I'd uploaded to a web server and then downloaded again. The original would open, but the downloaded copy returned the infamous "Cannot open file: -psm_0_xxxxxx" message. This was resolved with:

 xattr -d com.apple.quarantine test.xyz

So, that what psm stands for and what caused it in this instance.
