Can’t run app because of permission in Big Sur

  • 0

I installed Mac OS Big Sur yesterday and since then I am not able to run some old application. This is the message I get:

"You do not have permission to open the application"

I think this application is from an unknown developer. I tried different methods that were working in Catalina like:

spctl --master-disable

or I tried also to disable SIP and AMFI.

I’ve also tried

sudo xattr -rd com.apple.quarantine /Applications/my_app.app

If I run the app from the terminal this is the text version of the error I get:

The application cannot be opened for an unexpected reason, error=Error Domain=NSOSStatusErrorDomain Code=-10826 "kLSNoLaunchPermissionErr: User doesn't have permission to launch the app (managed networks)" UserInfo={_LSFunction=_LSLaunchWithRunningboard, _LSLine=2508, NSUnderlyingError=0x7fcb24c13ec0 {Error Domain=RBSRequestErrorDomain Code=5 "Launched process exited during launch." UserInfo={NSLocalizedFailureReason=Launched process exited during launch.}}}

Also tried to disable encryption and run:

csrutil authenticated-root disable

This is the error window:

      This solved my issue:

      Install upx with brew:

      brew install upx

      now run this command:

      sudo upx -d /Applications/my_app.app/Contents/MacOS/my_app

      you should put the path of your executable instead of “/Applications/my_app.app/Contents/MacOS/my_app”

      Then run the application normally.
