A common way to distribute malware is to take an innocent app and insert harmful code into it, and then redistribute the infected app. How to share files between mac pc. The safest approach is to look for a later version of the app from the Mac App Store or look for an alternative app. Basically, I used the native Safari.app web browser to download a third party application and I want to run / open it from the comfort of my bash shell / Terminal.app CLI; despite the following error. Opening an app from unidentified developer with a right or control-click overrides Gatekeeper for that specific app. From now on, you'll always be able to open it without having to go through the process again.

I am used to Windows but recently started using a restricted(can't run apps from unidentified developers) OS X machine and want to make it full featured without having to reformat, reset/recreate admin, etc.
I have MagicPrefs installed by just putting the file in a Programs folder under my user account and it just runs but gedit has a unidentified developer error and even a right click open requires admin privileges (I can not turn off gatekeeper from System Preferences)
Portable versions of OS X applications might be a solution for major apps.

Take an application you normally run, like one from the app store or the internet. Make sure you have permission to change it. For this, I recommend downloading a simple internet application like Keka, and dragging it to your desktop.
Duplicate the application by right clicking on it and selecting Open Package Contents. Drag out the contents of the application and fill the empty app shell with the content of the application from a unidentified developer.
The system reads it as an application created by a identified developer, and you can run it normally.

The only way to 'self sign' an app for Gatekeeper is to enroll in the Apple Developer Program (currently $100/annually), sign up for a code-signing certificate, and install XCode to create 'your' app.
You could then create an App in XCode and just include the contents of the other app you really are wanting to run in your app bundle, then sign it with your certificate. This app would able to launch anywhere (though you would possibly be violating the license of the original software).
What is the best slideshow program. Obviously this is not very practical. The method suggested in another answer here to copy the contents to another app's bundle will not, in itself, circumvent Gatekeeper. The 'Known Developer' check requires the the app bundle to contain a
_CodeSignature
subfolder, and an app ID which corresponds to the signed developer in the bundle's Info.plist
file. Both of these will be destroyed if you replace all the contents, and selectively replacing the contents will result in an app which has a code signature that does not match that of the app it is claiming to be.If this 'transplant' method does work, it is not because it tricks Gatekeeper; rather because it prevents Gatekeeper from ever being invoked. Regardless of whether an app bundle is signed, the Gatekeeper system will only check apps that are 'quarantined'. This means an extended attribute flag has been added to the file which indicates it was downloaded from the internet or else-wise from an unknown source. Safari and Mail will add this flag to downloaded files, but there is no requirement that all apps must behave this way. You can see this flag by running the command
ls -l@
on the directory containing your app bundle:If you copy the contents of an app into another app's bundle, the newly-created app has whatever extended attributes the bundle did beforehand. So if it did not have a
quarantine
flag, neither will your new app and you will be able to launch it. But if it did have a quarantine
Navigation programs for pc. flag, it still will, and Gatekeeper will be in effect.Transplanting the app contents is just a roundabout way of removing this flag. You can accomplish the same thing by simply removing the
quarantine
flag from the app directly, like so:How To Run Unidentified Developer On Mac For One Program Tv
or you could indirectly remove the
quarantine
flag by launching/allowing the app on another Mac (which does not have Gatekeeper restrictions in effect, or where you have an admin account which allows you to override it), then copying it to the restricted machine via a method that does not recreate the flag (apps copied from a SMB share, for example, will not be quarantined).Long story short: the right-click 'Open' (or 'Open Anyway' from Security screen of System Preferences) adds an exception to Gatekeeper for the app in question, which requires admin privileges. Removing the
quarantine
flag from an app only requires write permissions to the app bundle, and prevents Gatekeeper from ever getting involved.How To Run Unidentified Developer On Mac For One Program Xfinity
