Introduction

    With Mountain Lion, Apple has introduced a new security feature that is intended to prevent users from installing malicious software on their Macs, or at least encourage them to think more about what they install.

As per default, Mountain Lion will reject software that

1. Has not been downloaded through Mac App store, or
2. Does not come from an "Identified Developer", or, in other words, software that has not been signed.

To work around the rejection, simply hold down the control key while clicking the installer package. Mountain Lion will then warn you, and when you proceed, the software will be installed as normal.

How to allow for the Installation

1. open System Preferences >> Security & Privacy:

 

 

2. Click the lock symbol to allow changing the settings. In the section Allow applications downloaded from, select Anywhere.

3. A warning message will pop up. Click the button Allow From Anywhere to confirm the new configuration.

 

Try to Install and launch Star Watermark. It should work now.
