.osascript returned non-JSON response: start | iOS #164772
Description
I have been facing this issue for months. I had reinstalled macos multiple times, it works properly for sometime after reinstall then again same issue.
Fixes I have tried:
- Reinstall mac, xcode, flutter
- Upgrade to latest flutter
I have attached flutter run --verbose file.
Steps to reproduce:
- flutter run to an iOS device - Doesn't matter wireless or wired.
Alternate step to develop:
- flutter run (it'll fail, but open xcode and xcode will continue and install the app)
- flutter attach -d device-id
flutter doctor -v

@Quelaan1
If you create a new Flutter project and then try to run it, does it work properly or still give you same error ?
Did you also try this to see if it helps further ?
Quelaan1 commentedon Mar 7, 2025
Yes, that'll just run the app from xcode. No hot reload nothing.
If I do these steps, then I can use hot reload etc because of attaching
I'll try this now and let you know
Quelaan1 commentedon Mar 7, 2025
Nope, same thing:
darshankawar commentedon Mar 10, 2025
Thanks for the update @Quelaan1
It seems it could be due to combination of latest macOS version and iOS version you are trying to run. Is it only occuring while trying to run on iOS device ? If you select iOS simulator, does it work ?
Quelaan1 commentedon Mar 25, 2025
@darshankawar Yes, it works with iOS simulator
darshankawar commentedon Mar 26, 2025
@Quelaan1
I see that the device is wirelessly connected and then you are trying to select it to run your app. If you wired it and then run on it, does it give you same error ? Just trying to see and narrow down the use case.
I did try with my iphone device connected wirelessly and with wired, but didn't face any issue.
Quelaan1 commentedon Mar 26, 2025
It's the same as I have mentioned. @darshankawar
darshankawar commentedon Mar 26, 2025
ah I see, sorry I missed it. I am unable to replicate this reported behavior, but based on the report and error shown, I'll keep the issue open for team's tracking.
