In the early days on the Microsoft Windows OS I used Adobe Dreamweaver to do my coding and web developing. Cyberduck or FileZilla to FTP to my shared hosting. When I moved to the Apple Macintosh OS in 2006 I needed to look for other alternatives. I quickly found that Panic Inc. (est. 2004) offers beautiful and streamlined software. I use Coda for all my coding and file accessing needs. Transmit if I only need to access files. To get access to my servers on the go I use Prompt for iPhone and Diet Coda for iPad.
Shockingly good software.
