I need to FTP some files and I was wondering if you had a recommendation for a cheap program to use on the Mac (or maybe there is something already on here?). I used to use Cute FTP, but the version I have is for Windows.
Pardon a longer response, but there's some more general info below that may help in your mastery of the Mac:
Whenever I need software for the Mac, I go straight to Versiontracker or Macupdate, and search for the thing I need, in this case "FTP." Then I sort the results by "Product Rating." The user reviews are so helpful. Then I might sort by "License" to see if any of it's freeware, or at least cheap.
Even though I had a recommendation for you already, I just tried that search at Versiontracker, and found I needed to narrow it down a little further to "ftp client." (In software terms, "client" is one side of a "client/server" relationship, where a server provides services, such as FTP, web, email, what-have-you, to clients. The terms could refer to the application itself or to the computer it's running on. Examples: "We have a file server in our office." or "The FTP server software needs to be updated.")
Anyhoo, here's a link to the search.
You'll see that only four of the top 10 packages fit the bill precisely by having "FTP" and "client" in their description and are "freeware" or "shareware," and only Cyberduck is free. (Plus, its icon is a frickin' cute rubber duck, and you just want to squeeze it. One of my other oft-used Mac apps is a chicken. Y'know, you can't call many Windows programs adorable.)
I also found that Yummy FTP got good reviews, and I also know Transmit is very very popular. You'll see both of those list "advanced features," which you may not need, but if for whatever reason you find Cyberduck lacking, you may find those features, or just their interface or organization, worth the $25 or $30, respectively.
So, all you have to do is click on the link to one of those programs, and click "Download Now" over on the right. Your web browser will download and extract the installer. (Since you're in Leopard, you'll find the file in your Downloads folder, which is in your home folder and shortcutted in the Dock.) You want to make sure you install the app properly, which may mean just dragging its icon to the Applications folder, or double-clicking an instaler. After that you can throw out the installer file if there's one left in Downloads.
