How to run external QT program from PyQT5 on MacOS
-
What if you use the QProcess::startDetached method ?

What exactly are you packaging ?

Here is my project folder. Here is the actual run dolphin function. Hope that helps.

Did you try to use Popen with
shell=True? -

@SGaist It gave the same error
LSOpenURLsWithRole() failed with error -10810 for the file /Users/benjamin/Desktop/Dolphin.app.Oh and I tried starting the .app not executable in
/Contents/MacOS/ -
Which version of Qt are your application and Dolphin using ?

@SGaist I am using PyQt5 (I think version 5.12.2) And I have been informed that Dolphin uses 5.15.0 (C++). Although it seems that Dolphin uses this custom version ...maybe???
-
You should try with both using the same version of Qt.

My bad I was using PyQt5 version 5.15.5, but I will still try using Dolphins version.

@SGaist Ok so I update PyQt5 and I used
['open', '/Users/benjamin/Desktop/Dolphin.app/Contents/MacOS/Dolphin'],shell=Falseand it worked!
But then when I went to use['open', '/Users/benjamin/Desktop/Dolphin.app/Contents/MacOS/Dolphin', '--args', '-e', gamePath],shell=Falseto try to load a game, it gave me theopencommand usage dialog. Is there something wrong with using--args?
Also I tried things like opening with just/Users/benjamin/Desktop/Dolphin.appor usingshell=Truebut they also didn't work...I wonder if the arguments for Dolphin only work when running from the Dolphin.app and not the /Contents.... one.
Took a look and yep, the /Contents one doesn't support arguments... -

I don't know.
What exactly does "command usage dialog" tell you? You're probably using --args wrongly. -

open.Also, when launching the .app from Python, Dolphin starts then immediately crashes with this error message using Apples Crash Message Screen Thing: https://pastebin.com/NqBK0YvQ (It also shows

Try to pass it -h parameter to get more information.
