If you’re a web developer who’s using a Mac, then chances are you’ve come across at least one the popular development tools for a Mac. There’s nothing wrong with preferring a Mac for web development or everyday needs, especially since you’re right in the middle of a world open to countless quality applications that simplify a web developers life, and many are Mac exclusive. This is not to say that you can’t develop stunning graphics and websites using another Operating System, but with Mac applications, you can reap the benefits of their amazing user interfaces.

Below we’ve compiled a list of 18 Essential Apps for Web Development on a Mac. Hope you enjoy! Please remember to subscribe to our feed and leave us a comment with your thoughts!

BBEdit

BBEdit is another full-featured text editor that is very similar to Textmate in terms of features. The BBEdit product page even has a section for web developers to see the benefits of BBEdit. For those Mac users who think BBEdit is better than Textmate, it’s usually because BBEdit is a Cocoa application, and TextMate is a Unix application. Without getting into the nitty-gritty between the two editors, the main differences between the two applications are 1) look-and-feel and 2) price. BBEdit is a steep $125, more than double the price of TextMate.

MAMP

MAMP is a quick and painless way to set up Macintosh, Apache, MySQL and PHP in the same environment. What used to be a tedious process now literally takes just a few seconds between downloading MAMP and installing the software. Instantly you’ve got a fully-functional web testing environment for your PHP applications. It also comes locked and loaded with PHP extensions like Zend, and you can specify different cacheing types like APC, eAccelerator or XCache.

You can apparently use MAMP to run a Rails environment as well.

Apanta

Aptana to the list. Aptana is a programming environment for languages like PHP, Rails, Java, Ajax, Javascript and others. The software also comes with optional plugins like Adobe AIR and an iPhone environment. Apanta is free to use for everyone.

Cyberduck

Cyberduck is an incredibly user friendly FTP client that’s provided for free and licensed under GPL. It can be used in many different settings, like FTP, SFTP, WebDAV and Amazon S3 straight out of the box. Cyberduck also integrates seamlessly with essential Mac functionality, like Bonjour, iDisk, Growl, AppleScript, Spotlight and even Quick Look to instantly see the guts of the file with a tap of the spacebar.

My favorite aspect of Cyberduck (aside from the free-ness), is the fact that it integrates easily with many text editors like Textmate. As an added bonus, Cyberduck also allows you to use Quicksilver to access your FTP bookmarks. Very handy.

Transmit

If Cyberduck is a cadillac of FTP clients, than Panic’s Transmit is a Rolls-Royce. It offers almost all of the same functionality as Cyberduck, but adds a little more robustness for advanced user. For example, you can edit any remote file (even a picture or graphic) in any software using Transmit.

The only downside to Transmit is that it costs $29.95, whereas Cyberduck is free.

cssedit

cssedit is a CSS editor with a fantastic user interface. It has the look and feel of a Mac application, which makes the experience of editing CSS much more enjoyable. It has nice built in features like being able to extract stylesheets and learn from other other websites, an inline visual editor, and you can even edit css inside of ajax.

cssedit will cost you almost $43, but if you’re a sucker for beautiful interfaces, this software might be exactly what you’re looking for.

Coda

If you’re building a site from scratch, it’s nice to have a program like Coda where you can manage all the files and FTP functionality from within one program. Built by Panic, the same guys who develop Transmit, Coda is a one-stop solution for web developer. Within code you can manage files, ftp to a server, preview the code, use a css editor (like cssedit), and even use Terminal all from within Coda. And if that weren’t enough, they’ve thrown in a copy of The Programmer’s Desk Reference from within the software.

Changes

Changes is a nifty application that lets you visually browse changes to your code base. Instead of having to use a subversion to manage your code base (though Changes works with svn and other repository software), you can use Changes. This is great for sites that have multiple developers working on them and want to make sure their code is up to date. You can use your favorite text editor like Textmate or BBEdit to edit files.

Colloquy

IRC is an old skool method of chatting online, and has been the method of choice for programmers and developers to communicate. Many major projects like Wordpress use IRC to provide support for their open source projects.

Colloquy is an extremely helpful IRC client for the Mac. It’s open source, allows for plugins and styles, and even has an iphone interface. Robust, elegant and powerful.

SubEthaEdit

SubEthaEdit is a collaborative text editor for the Mac. You can use the software as a text editor, note-taker and for co-writing text. It integrates with Bonjour, iChat and Mail, but isn’t limited to those integrations. SubEthaEdit also has a fairly robust editing syntax for many different languages. So really, this is a swiss-army tool for developers that work in a collaborative environment that share code often. It’s not free (around $54), but SubEthaEdit could be well worth the price given its usefulness.

Terminal

The built-in Terminal is a great place to start when working with the command line. There’s a great guide to learning Terminal, but essentially Terminal is a bare-bones tool that allows you to do just about… anything. I’d recommend you read the tutorial for a better explanation (as it’s outside the scope of this article). I’d also recommend snagging the Quicksilver plugin for Terminal to help speed your usage.

iTerm

If you’re looking for a way to ease the pain of using the command line and Terminal, try iTerm. iTerm is a “Terminal emulation program” that adds a bit more functionality and user friendliness to Terminal. It offers features like multiple tabs, bonjour support, bookmarks, and much more.

phpMyAdmin

phpMyAdmin is the kindly old grandfather of database management scripts. Not necessarily hip to an attractive user interface, phpMyAdmin still has the skills to pay the bills. You can manage your databases locally using this stable script. It ships with MAMP, so installation is a breeze. If you’re not MAMP, then you’ll have to configure PHP to run on your Mac, which is a much more involved process. Still, phpMyAdmin is a tried and tested solution for managing databases with a UI.

CocoaMySQL

CocalMySQL is a database tool developed specifically for Mac with Cocoa. It has the elegant look and feel of a true Mac application, and is laden with features. CocoaMySQL is much easier than phpMyAdmin on almost all fronts; it’s easier to setup, has a much more intuitive interface, and runs more like a Mac program. The software is also licensed under the free GPL license.

Quicksilver

Quicksilver is a launcher tool that does so much more for developers. If you’re wanting to save time and keyboard strokes, consider giving Quicksilver reign over your computer. For more information as to what Quicksilver is, check out Lifehacker’s introduction to the Mac launcher.

The real beauty of Quicksilver lies in the countless plugins with software that many web developers already use.

Xcode

Xcode is Apple’s development package. This gi-normous 900mb download adds tons upon tons of system mojo that you’ll probably have to eventually install to your system that you’ll probably use down the line. Many serious development software like SVN and the like use dependancies that Xcode takes care of. Xcode is free for the taking.

Isolator

While Isolator isn’t a crucial application for developers, it’s quite handy for blocking out distractions while you’re getting work done. Isolator is a free program that blocks out everything but the single application you’re working on. This gives a distraction-free environment for writing, programming, or whatever else needs your attention. Just tap the keyboard command cmd + shift + I (or use the toolbar menu) to start/stop Isolator.

Spaces

Spaces is a handy built-in application for Leopard users. It allows you to set up virtual “spaces” for different screens on your computer. This is helpful for developers because you can separate your work flow into different panes. For example, you could have ftp and terminal open in one space, Textmate in another, Firefox in the third and Gimp or Photoshop in the fourth. It’s easy to toggle between the spaces using the command ctrl + arrow, or you can use ctrl + the number of the space you want to switch to.
