This Mac error indicates that installer data may either be corrupted or a permissions conflict is preventing the installer from reading the data. This error may be caused by an unstable internet connection, security applications interfering with the download, invalid permissions for OS X, or hard drive corruption.
- If you're using a wireless connection, optimize your internet connection to rule out a connection issue.
