Many developers these days are moving towards Macs for primary development machines. Unfortunately, some legacy bug tracking software does not work well on Macs. FogBugz is web-based bug tracking software, which you access through your browser. It will work wonderfully on Safari (as well as other modern browsers), and since there is nothing to install, you don't have to worry about compatibility issues or administering your own server. Try FogBugz free for 45 days.
FogBugz includes revolutionary Evidence-Based Scheduling, which lets your team estimate how long particular tasks will take them and, over time, learns who produces accurate estimates, allowing the system to predict with confidence when milestones will be met. It even lets that prediction get a little fuzzy: with 90% confidence you'll ship in May, with 95% confidence by the second week of June, etc. So if you're worried about getting the project done in time to enjoy the new iPad release, EBS will let you sleep easy at night.
FogBugz is the flagship product of Fog Creek. If you haven't already heard of us, we're basically a feisty, independent company that does nothing but make great software for great developers. You can think of us like Panic from a parallel universe where they use Windows. FogBugz oozes all of the little touches that suggest it was made by developers, for developers: we obsessively polish every interaction to focus on your productivity, for example. Mac developers in particular will appreciate our new design, which models a problem that isn't necessarily the sexiest but still manages to look decent.
As a small company, we take pride that our software works wonderfully for our customers. Your problems with it are our problems -- probably literally, since we run our entire business off of FogBugz running on the very same machines your account will be running from. So if something isn't working right or if you just want to ask how FogBugz can better support your team in writing great software, we want to talk to you. Phone and email support are free for customers of hosted FogBugz, even during the free trial.
Mac users know that good software doesn't force users to figure out how to use it. It guides you to success, with a definite point of view on the right way to use it and sensible defaults. FogBugz is optimized for the development practices that we think are essential for good software development. However, if it doesn't quite match how your shop operates, there is a rich Plugin system to allow you to customize the workflows to match your existing practices. You can even interact directly with the FogBugz API if you would like to integrate with systems we do not already support.
The best feedback is feedback direct from your users, so FogBugz doesn't force you to put a human between your users and the bug database. If you want, you can have users email a special FogBugz address directly (or forward email there), and we'll parse the emails and create issues in your tracker automatically. No configuration is required and we set attributes like Title intelligently. We also use Bayesian filtering, just like Mail.app, so that your bug tracker doesn't get overwhelmed with Viagra spam.
Mac development shops don't hesitate to splurge if it will increase developer productivity. After all, those Macbooks don't come cheap. (Sorry, perhaps that was a low blow.) FogBugz is easily affordable on your team's budget, at only $25 per named user per month. Save the money you would have spent on more expensive bug tracking systems and spend it on other independent software instead... or maybe iPad2s for everybody. (Did we mention that FogBugz works on iPhones, iPads, and many other leading mobile systems?)
