on your mac in prefs you have sharing , in there is a tick box for windows share
once enabled you will need to set up a user name and pass
it will give you an ip address like \\10.10.10.10\macrumorsmember
try it by typing this into the address bar in windows , a box will pop up with username and password - type in and you just made it work!
to save this network drive go to tools and map network drive - selct drive letter and pop address in - put user name and password in and your done
all done from memory not that good so might have forgot something there🙂
