MachOView

Hungry Apple icons by Nicholas Boyd (http://loafninja.deviantart.com)

Install with Homebrew

brew tap bplaat/machoview https://github.com/bplaat/MachOView.git
brew install --cask bplaat/machoview/machoview

MachOView requires macOS 26 or later.

todo:

  • code sections parsing on demand
  • string table

ver 3.0.10000

  • Added current Mach-O load commands, chained fixups, filesets, modern thread states, and relative Objective-C method lists
  • Hardened parsing of malformed and truncated binaries
  • Added native Apple silicon support and deterministic runtime validation
  • Refreshed the interface, application icon, credits, and release packaging

ver 2.4.9200

  • Lots of leaks fixed
  • Updated disassembler from cctools-855
  • Updated llvm disassembler from libLTO OSX10.9
  • ARM64 relocations in detail (need to review)
  • Added new load commands

ver 2.4.9000

  • ARM64
  • LC_ENCRYPTION_INFO_64,LC_LINKER_OPTION
  • data in code and entries (DICES)
  • updated disassembler (cctools-845 and LLVM with enhanced symbol table)
  • SDK 10.8 / deploy 10.8
  • fix for multithreaded usage of CoreAnimation

ver 2.3.8505

  • updated disassembler (LLVM included for testing)
  • some GUI improvements (PreferencePanel)

    • do not reopen unclosed binaries
    • some new Load Commands
    • bugfixes

ver 2.3.8345

  • Transition to ARC (but targeting OS X 10.6 for compatibility)
  • FAT binary layout in details
  • LC_ENCRYPTION_INFO,LC_PREBIND_CKSUM,LC_RPATH,LC_FUNCTION_STARTS
  • twolevel swapping for smaller memory usage and better GUI response
  • Better ObjectiveC 2 section parsing

ver 2.2.6500

  • objC sections
  • crash fix for concurrent treeView update
  • crash fix for disassembler (could read beyond file data)
  • relocs/bindings stored in a shadow NSData for faster access
  • improved exception records parser

ver 2.1.5290

  • mainly bugfixes (relocInfoInfo, static libraries)
  • stop button for cancelling background tasks
  • exception safe symbol/section namelookup
  • disassembler updated to cctools-806

ver 2.0.5000

  • ARM support
  • symbolic disassembling of text sections (based on otool)

  • two-level namespaces in details
  • export dylibs (e.g.: libSystem.B.dylib)
  • safer symbol/section table access

ver 1.2.2632

  • some command binary representation (dyld info, routines, two-level namespace)

  • 64bit exception data and relocation fixes
  • more stable name unmangling in tooltips

ver 1.2.2200

  • coloured background for special items:
    • local/absolute indirect symbol
    • scattered relocation
  • edit and save function
  • RVA/RWA offset uses segments' properties for calculation
