Unexpectedly is a tool for macOS developers (or users) who need to look at crash reports for macOS applications.

Find the reports

Unexpectedly lists all the reports for the current user (and the system reports if you are a user with administer privileges). You can also list reports from other sources and group reports according to custom criteria.

To read more on this topic, see chapter 3, "Using the sources and reports lists".

Let there be colors

Unexpectedly analyzes the contents of reports and presents you text reports enriched with syntax highlighting and hyperlinks (fig. 1).

Alternatively, you can also opt to focus on the backtraces of reports by using the outline views (fig. 2).

To read more on this topic, see chapter 5, "Text reports" and chapter 6, "Outline reports".

Register for free

Unexpectedly can display the registers state at the time of the crash in a secondary window. You can cast the values of registers to a selection of types.

To read more on this topic, see chapter 8, "Inspector and Registers window".

Make it your own

It is very easy to personalize the appearance and contents of reports using the preferences of Unexpectedly. It's up to you to create your own themes and define what should be visible or not.

To read more on this topic, see chapter 9, "Preferences" .
