Can't run app because of permission in Big Sur
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:
Answer
Open Terminal or iTerm and type sudo chmod -R 755, then drag the .app into the window, which will bring the full path into Terminal or iTerm. This worked for me, moving the -R option directly after chmod.
It will look like this:
sudo chmod -R 755 Path\ to\ app\ file.app
Press return.
