Bit Slicer is a universal game trainer for macOS, written using Cocoa and Mach kernel APIs.

It allows you to cheat in video games by searching and modifying values such as your score, lives, ammunition, and much more.


  • Memory Scanner
    • Search & narrow down values of several types: integers, floating-points, strings, byte arrays, and pointers
    • Add, delete, and modify variables with ease
    • Freeze variable's values
    • Store a process' entire virtual memory space and search for values based on incremental changes
    • Manipulate pointers by dereferencing variable addresses
  • Memory Inspection
    • View and edit memory live in a hex editor style window
    • Dump memory to files on disk for manual inspection
    • Modify memory protection attributes
  • Debugger
    • Watch for what instructions access a variable in a document
    • View live disassembly of instructions
    • Modify instruction's bytes directly, or by assembling instructions (including nopping)
    • Set breakpoints, resume from them when they're hit, view backtraces, manipulate thread registers, and step into/out/over instructions
    • Inject new assembly code on the fly
  • Save slice documents so that you can send cheats to your friends
  • Write Scripts to automate tasks that involve using virtual memory and debugger methods
  • Pause and un-pause current process
  • Undo & Redo many kinds of changes, including searches
  • Evaluate mathematical expressions automatically (eg: in a flash game, search for 58 * 8)
  • Run as a normal user, not as the superuser (root)!
  • Enjoy OS level features such as auto-saving, document versioning, window restoration, notification center, app nap, dark mode, etc.
