Often I download tools and applications from the internet.
Since Mountain Lion, Apple has integrated a new security feature. This feature divides applications in two groups:
- verified applications
- unverified applications
When you try to start a new downloaded application (unverified) the operating system open a dialog window saying: "[Application]" can't be opened because it is from an unidentified developer.
and you cannot run the application.
If you want to run your application, and if you have downloaded it I think you want also run it
Before closing the dialog window:
- open System Preferences
click on the "security & privacy" item
- you should see something like the following
- click on the "open anyway button"
- then launch again your application
You may want to apply this setting to all the applications you will download from the internet:
in the "security & privacy" panel
- click on the lock icon to make changes
- insert your password
- click on the Anywhere item
- and click again on the lock icon
Now your operating system will open all application without asking you. Remeber that, in this way, your Mac will be just a little bit insecure.
