$ sudo rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

$ sudo yum install kmod-hfsplus

$ sudo yum install kmod-hfs 
$ sudo yum install hfsplus-tools

after install, you might need reboot

use force option to activate read-write mode

$ sudo mount -t hfsplus -o force -o rw /dev/sdc2 /media/disk1/
