Mac OS X Not Supported by JIRA
Mac OS bundles a separate version of JAVA within the OS, as result unknown issues can occur when running JIRA in that environment.
java.vendor : Apple Inc. java.vendor.url : http://www.apple.com/ os.name : Mac OS X
Mac OS X is not one of JIRA's Supported Platforms.
JIRA is a pure Java-based application and should run on any supported operating system, provided that the JDK / JRE requirements are satisfied. That being said, the Mac OS is not officially a supported platform and therefore we can provide minimal support if the issue is an OS related issue running the JDK / JRE.
Migrate the JIRA instance to Windows or Linux, as listed on the Supported Platforms page.
