Big Sur Problem?: "You do not have permission to open the application"

I have tried EVERY single work around for this issue, and still have the same "You do not have permission to open the application"
if I move the application to any mac not running Big Sur it works fine. move it back to Big Sur, doesn't work.

Code Block 
codesign --force --deep --sign - /Applications/AppName.app

This worked for me on macOS Big Sur. Arqtistic posted a link to Stackoverflow. ajmas mentioned that some of you may have problems opening apps because of a signature error. This signs the app again. Make sure to replace "/Applications/AppName.app" with your app by removing this line and drag and drop you app into the terminal, so the path gets automatically copied.

This may not be the solution for everyone. You may have to use "sudo spctl –master-disable" before. Don't forget to enable it again even if nothing worked.

the below info worked for me.

open terminal. 
enter sudo chmod -R 755
then drag and drop the application you are trying to open.
click enter 
then enter your password

I experienced also a problem with the permission to open an application. Nothing solved the issue, whatever I tried.

I was using Archiver.app, and could not imagine that this App might be the reason of the problem. But, then I tried Archive Utility.app, and all worked fine.

In case you have a problem with permissions of opening an App, just try to use another decompressing App.

i found something that worked, at least for me. go to finder, then applications, find the application you are trying to open, and then right click it. in the options that come up, click "new terminal at folder". once the terminal is open, copy and paste " chmod -R 777 . " (with the dot!) then click enter. now try to open the application again. it should give you an error saying that the app is not trusted or something like that, but you can override this by just going to finder, applications, then right clicking the app and clicking open. this will manually let you open the app. hope this helps or wasn't too confusing, i'm not very good with the script stuff :)

tried everything, but only resign helped:

error was (via terminal $open /App):

Code Block 
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=0x7fa5f3806a50 {Error Domain=RBSRequestErrorDomain Code=5 "Launch failed."

I had it working, I tried first:

Code Block 
xattr -r -d com.apple.quarantine app.app

Then:

Code Block 
sudo xattr -r -d com.apple.quarantine app.app

And then:

Code Block 
sudo chmod -R 755 app.app

go to terminal and type

chmod -R 755 (file path)

Instead of manyually typing it you can drag and drop it. then press enter/return and right click the app, they click open.

It has something to do with the enclosing folder permissions. Try "sudo chmod -R 755" on the enclosing folder... I just had this problem with new Opera Installer and this old trick ("sudo chmod -R 755 OperaSetup") has worked like a charm, whereas the other proposed solutions failed.

Yeah unfortunately nothing has worked for me. I have tried literally everything that is on this form and others on the Internet. The only way I can temporarily circumvent the issue, is to reinstall the app from its original source. But then after 24 hours, it always will pop up this message again.

You do not have permission to open the application Contact your computer or network admin for assistance.

But I am the only admin on this computer, what's going on Apple?

@K714 same thing here nothing works so frustrating this Gatekeeper thing is really anoying. Even I setup a separate account as Admin same issue.

This got it working for me.

sudo chmod -R 755 Application.app

I too have tried all methods on this page and others but still cannot get any apps off the internet working.

This problem have several solution. They differ according to the type of the application you want to open. You can find all the possible solutions in this article https://www.itech4mac.net/apps-troubleshooting

I have an answer (sorry for a little late): If you go into the app's contents (right/control click, Show Package Contents, Contents, MacOS), a file with the same name will come up. Open terminal, and type in chmod +x then drag & drop that file and press enter. The application should now work!
