Weird indeed. I'm puzzled to see some flutter reference here (process_run is for the dart vm - not tested on flutter - and I'm not sure how Process behaves on Flutter (I guess desktop here)). Since process_run relied on https://api.dart.dev/stable/2.5.1/dart-io/Process/run.html can you try the raw implementation first?

[Danopie]

@putraxor Have you figured it out? The raw implementation yields the same result.

[putraxor]

@Danopie I use the default Process.start on Flutter Desktop (macOS) and disable sandbox mode on xcode

[Danopie]

Thank you @putraxor, in my case only turning off the sandbox mode does the trick

[Timmmm]

For future googlers, to disable sandbox mode comment this out in macos/Runner/*.entitlements:

<key>com.apple.security.app-sandbox</key>
<true/>

[janoschp]

Well this is not a solution because I don't want to disable sandbox mode. How can I run a process without disabling sandbox mode?

[hongfeiyang]

I don't want to disable the sandbox mode either. It messes up with user's documents folder.

It’s been three years, brother. Have you found a solution yet?​ @janoschp

[janoschp]

@LittleHans8 bruh, what do you think? I don't even work with Flutter anymore, I don't even remember why I asked this question.
