When you try to install an application on a Mac, you may get a message saying "Your security preferences allow installation of only apps from the Mac App Store and identified developers." A security setting is preventing the installation. Here's how to adjust the setting so you can run the installer:

  1. Open your System Preferences.
  2. Open Security & Privacy.
  3. From the General tab, click the padlock icon to make changes, then enter password as directed.
  4. Change the Allow apps downloaded from: setting to Anywhere.
  5. Click the Allow From Anywhere button.
  6. Click the padlock icon.
