Please send bug reports via email.

A great bug report always contains the following essential parts:

1. SUMMARY
2. SETUP
3. STEPS TO REPRODUCE
4. EXPECTED RESULT

5. ACTUAL RESULT

   If you’re feeling especially helpful, one additional part is always appreciated:

6. ADDITIONAL NOTES (OPTIONAL)

Let’s break these down.

1. SUMMARY

   A one (or maybe two) sentence, high-level description of the problem. This is almost like the subject line of an email.

2. SETUP

   This is where you tell the developer about your setup. Three things are vital:

   1. The hardware device you’re using. (like iPhone 5S, or 2013 MacBookPro Retina)
   2. The OS version you’re using. (like iOS 7.2, or OS X 10.9.4)
   3. The specific version of the app you’re using. Include build numbers if possible. (like Mail.app Version 7.3 (1878.6), or TextMate version 2.0-alpha.9551)

   If you’re reporting a bug on a website, substitute the name and version of the web browser you are using for the app name and version.

3. STEPS TO REPRODUCE

   This is the most important part. Break the issue down into a specific numbered list of steps that always (or at least sometimes) reproduces the problem.

   Seriously, break it down into a numbered list of steps. Here’s an example:

   1. Visit example.com in any browser listed in SETUP above. See normal "Home" page appear.
   2. Click blue "compose" button. See "compose" text area appear
   3. Type "hello world" in compose text area
   etc…
   

4. EXPECTED RESULT

   Sometimes the desired outcome you expect is not obvious to the developer. Just to be safe, spell it out here in one short sentence or phrase.

5. ACTUAL RESULT

   This is what you’ve been waiting for. Here’s your chance to describe what is actually going wrong. Make this section as long and detailed as you like. In fact, rant away! Since you’ve already provided a numbered list of steps to reproduce the problem (you did provide a numbered list of steps, didn’t you?), you’re now free to complain all you like about what’s going wrong.

   If the app crashes, describe that here, and include the entire crash log, please.

   And finally, the optional part:

6. ADDITIONAL NOTES (OPTIONAL)

   If you’re feeling especially helpful, fee free to provide additional info here. For example, if you know what version of the app or the OS this issue first appeared in, please mention that here.

   If you’re reporting a bug in a website, did you try to reproduce it in multiple browsers? (That’s always a great idea, BTW.) Great! Tell us about it here.

   If you’re reporting a bug in a Mac app, did you simultaneously run Console.app and capture some suspicious-looking console logs? (That’s always a great idea, BTW.) Great! Tell us about it here.

Below is a template to get you started. Please copy and paste this into an email or your bug reporting sofware of choice and start from there. That’s it! Thanks for reading, and happy bug reporting. :)
