Googling for ftp mac finds http://www.creativemac.com/2002/09_sep/tutorials/ftposx020924.htm telling it's built into OS X 10.2
Since you only say "Mac" and nothing about the OS version (and they change much more frequently than the versions of Windows, I'm afraid) I can't tell if this is a good way to go for you.
Why not try our Mac OS or Mac Applications forum? We've a very good mod there and rather specialized visitors.
I am new to uploading sites. I have a domain name and created my website with Dreamweaver . But dreamweaver suxs it doesnt download my website so i was told that it is easier and more secure to download and FTP server. Does anyone recommend one for the MAC that is FREE?
