Motivation

The macOS system utility Console.app is pretty limited and confusing when it comes to browsing crash reports.

Minimum OS requirement is macOS 10.13 at this time.

Development Environment

  • macOS 10.14 or later
  • Xcode 10.1 or later
  • Objective-C 2.x

Potentially Interesting Implementations In The Code

  • Code to access the segments and sections of a Mach-O file is available in the app_unexpectedly project/app_unexpectedly project/Mach-o directory.

  • Code to analyze DWARF files is available in the app_unexpectedly project/app_unexpectedly project/DWARF directory. Unexpectedly does not rely on LLVM.

  • A solution to deal with a NSTextView when it comes to vertical scrolling when a vertical ruleview is visible is available in the CUICrashLogTextView class.

  • How the project uses - forwardingTargetForSelector: , - respondsToSelector: to go downward in the responders chain might be interesting.

  • Code to implement a thick NSSplitView divider with subviews as in Xcode can be found in the CUICrashLogPresentationOutlineViewController class.
