About two years ago, I wrote a very popular piece for The Simple Dollar called. In it, I talked about how I had a new Dell laptop and that I didn’t want to spend a lot of money on additional software for it, so I went hunting. I sought out open source software so that I knew it would be not only free, but the code would be peer-reviewed and it wouldn’t have any bugs or malicious elements in it. And, eventually, I that really met my needs. Eventually, though, I switched to using a Mac. And, just as with my PC, I wanted to find a lot of open source software to meet my basic computing needs.

I didn’t want to shell out the big bucks for Office or other such expensive pieces of software – I’d already spent enough. So I went hunting.

What follows is a list of twenty five pieces of software that are the cream of the crop of open source software for Macs. Not only is every piece of it free, many of them directly replace expensive software packages. Firefox Replaces Internet Explorer and Safari Safari is a very solid web browser out of the box, but it’s not nearly as or useful as Firefox. With add-ons like, and, plus the speed and reliability I’ve come to expect, Firefox is the only web browser for me. Quicksilver Unique but useful (productivity) Quicksilver lets you set almost anything you can imagine in Mac OS as a keyboard shortcut. This allows me to do things like start iTunes and have it auto-play a specific podcast with a specific keyboard shortcut (I have one that auto-plays This American Life, for example).

It’s a bit complicated at first, but once you get used to it, it makes you feel massively productive and it becomes almost an essential part of the OS. Thunderbird Replaces Mail For most purposes, the default Mac OS Mail does the trick, but I find Thunderbird essential because it allows me features like auto-replying to certain kinds of messages and far better IMAP support, and it’s faster, too. Even better – it works identically both on my PC and on my Mac. Sunbird Replaces iCal I like iCal, but Mozilla Sunbird does one thing that iCal doesn’t – two-way syncing with Google Calendar. When I’m traveling, I’ll use Google Calendar at any terminal I’m at to print out tomorrow’s schedule, make little changes, and so on. When I get home, it’s just a click of a button and it all syncs up with Sunbird.

That’s an amazing feature for me and it makes Sunbird far superior to iCal. AbiWord Replaces Microsoft Word This is, by far, the best open source word processor for Macs. It functionally replaces Microsoft Word for almost every purpose I’ve come across and has a fast and slick interface to boot. This is the word processing program I used to write my book with, in fact.

OpenOffice Replaces Microsoft Excel and PowerPoint Need to make spreadsheets or presentations on your Mac? OpenOffice provides the tools you need for that (as well as word processing, but I prefer AbiWord for that). I often use OpenOffice Spreadsheet for the number calculations you see on The Simple Dollar, as well as using it for tracking my net worth (as ).

Seashore Replaces (for most uses) Adobe Photoshop This is a fairly simple image editor that takes care of most of the basic uses of Photoshop and is simple enough for most users to pick up. This is a great solution for those who want to do simple image manipulation but don’t want to shell out the big bucks for Photoshop. Scribus Replaces Adobe Pagemaker (desktop publishing) I’m actually elbow-deep in Scribus right now as I work on a special side project. It’s a very powerful desktop publishing program, giving you tons of freedom to lay out pages however you like. Another use: I’m thinking about making a family newsletter to ship out in the Christmas cards this year. Adium Replaces iChat iChat is pretty slick, allowing me to chat in AIM and GTalk at the same time, but what about all of the other chatting protocols out there. Adium allows you to be on YahooIM, Windows Messenger, AIM, ICQ, and several other messaging services at the same time with the same program.

OneButton FTP Replaces “command line” FTP On occasion, I need to FTP some files from one place to another (usually from one computer to another within our home network, when I’m too lazy to use a memory stick). OneButton FTP does the job in the simplest and easiest way possible – much easier than the default “command line” FTP. Audacity Replaces/supplements GarageBand Need to make audio recordings of your own?


All you need is a microphone of some sort and Audacity – and you can create podcasts, record music, or pretty much anything else you can imagine. I’ve actually considered using it to read aloud some bedtime stories for my kids in advance of any traveling I might do.

Cashbox Replaces Quicken This is a very nice personal finance data manager for Mac OS. It doesn’t have quite all the bells and whistles of Quicken, but it provides a strong feature set and a huge number of different views of your personal finance state. If you’re a Quicken fan but don’t want to drop the cash for a Mac version, look into this one. Vidalia Unique but useful (privacy) Many people are concerned about online privacy and don’t want their IP address shared with web sites that they visit or file servers that they access.

Vidalia easily allows you to use proxy servers for your accessing needs, enabling you to disguise your computer on the internet. Books Unique but useful (book cataloguing) This one’s just for fun, but I’ve found it very useful. It allows you to catalogue all of your books, create reports, and so forth. I’ve been using it heavily in conjunction with to help me as I read through a pretty big pile of classic literature. Bean Replaces TextEdit I use this software for the editing of virtually every post that appears on The Simple Dollar. It’s a slick little editor with features like automatic word counting that really help when you’re trying to keep some semblance of control on the length of your articles.

GanttProject Replaces Microsoft Project This is an excellent tool if you’re involved in the management of large projects with many staff members, particularly if budgeting is tight (as Project can be expensive). One of my closest friends uses this for mission-critical projects in the workplace.

Nvu/BlueGriffon Now: Soon: Replaces Dreamweaver (HTML editing) I prefer coding my HTML by hand, but many people prefer the aid of a tool to help them with layout, and that’s what these provide. Nvu is a bit outdated but is still very useful – the creator has moved on to a new project, called BlueGriffon, which should be available soon. Blender Unique but useful (3D graphics creation) Blender is a magnificent tool if you like tinkering with 3-D graphics creation. It’s perhaps overkill for most people, but if you’re involved in graphic design at all, using and knowing Blender can be invaluable.

Open Source Software For Mac Os X

Colloquy Unique but useful (IRC) If you chat on IRC, Colloquy is essential software. For the uninitiated, IRC is a very large network of chatrooms on various specific topics, often developing their own culture. Colloquy is a wonderful solution for IRC chatters on Macs. FreeMind Unique but useful (brainstorming) Whenever I’m struggling to organize my thoughts and ideas, I open up FreeMind.

Basically, it’s a tool that lets you toss out your thoughts in an unorganized structure, then build connections between them however you like. I often use it for posts where I have a collection of thoughts and research notes, but I haven’t really decided how to order them or tie them all together. It’s brilliant in any brainstorming setting. Celestia Unique but useful (planetarium) If you’re a space buff (like I am), Celestia is incredible software. It’s a great way to create star charts, help you identify good nights for viewing constellations and other stellar objects, and simply stumble around different views of the sky. I simply love looking at the night sky, and Celestia is a wonderful free companion for this hobby. Transmission Unique but useful (file sharing) Many people like to upload and swap their own files with other users, such as live recordings of concerts, recordings of their own performances, free application software, and so on.

BitTorrent is one of the most popular protocols for doing this, and Transmission is easily the best of the open source Mac clients for swapping them. MacLibre Supplements Software Update Many of these software packages are updated fairly regularly by their authors. MacLibre serves as something of a “Software Update” tool for these things, fetching updates for you and helping you to easily install them with just a click or two.

Mac Open Source Software For Machine Vision

It’s a great way of keeping up to date on software updates for open software on a Mac. Aleph One Gaming Like games like Quake and Half-Life? Aleph One is an excellent open source game in this vein, available for the Mac. The graphics are a bit on the simple side, but online play is quite slick and one can’t argue with the cost. Battle for Wesnoth Gaming The final choice on this list is a turn-based strategy game with a fantasy theme. Battle for Wesnoth presents you with a wide array of scenarios that require you to take turns moving pieces around the landscape, thinking about your moves, and engaging in skirmishes.
