First , you need to share your files in MacOS
Do the following things in redhat
yum install samba-client cifs-utils
edit this file : /etc/fstab
ad this line
//192.168.1.6/Documents /data cifs user=user,password=password 0 0
then run: mount -a
if you receive the error
mount error(95): Operation not supported
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
then change the line to (vers=3.0)
//192.168.1.6/Documents /data cifs user=user,password=password,vers=3.0 0 0
