Unable to Install Package

I got the error below when trying to install the pkg but got the error below

“FiveDesktop-x86-2.1.pkg” can’t be opened because Apple cannot check it for malicious software.

Hi femi,

The reason this is happening is because we are still in the process of signing the Five Installer and executable with Apple, this will make Apple see us as non-malicious. To get around this please follow these simple instructions using the below link.
