This article applies to: JIRA Client 3.5.1 running on OS X 10.9 Mavericks operating system
Problem
Trying to launch the application for the first time, you get a message from OS X that reads "This app is damaged and can't be opened".
Solution
OS X Gatekeeper shows this message because the application bundle is not digitally signed. To run the application for the first time, you will need to disable Gatekeeper as follows:
- Go to System Preferences... | Security & Privacy | General tab.
- Click the Lock icon in the lower left corner and enter your password to make changes.
- Select Allow apps downloaded from: Anywhere.
You can enable Gatekeeper again after the first successful launch of the application.
