Updating Clover Failed

I am currently on El Capitan (10.11.6) and I am trying to update to Sierra. The first step is to update Clover. I have downloaded the latest version (2.4 r4380) but I get an error "This package is incompatible with this version of OS X and may fail to install." Any help? I have already tried install older version and they all have the same error. Thanks
