Unexpectedly 1.0
Unexpectedly is a Mac application that lets you browse and visualize the reports from crashes that happened on your Mac or, more probably, another one.
Unexpectedly knows how to parse macOS crash reports. Unexpectedly processes the crash reports to display them as text with colored syntax and hyperlinks or as outlines. A broad range of options are available to let you customize how and what to display.
Unexpectedly can symbolicate the backtraces of crash reports using either the dSYM archives you provide or the ones it has automatically found on your Mac.
This seems really well done, it has documentation, and it’s even open source.
