Bit Slicer is a free, open-source macOS game trainer and memory inspection utility that modifies values inside running applications. It allows users to search process memory for variables such as scores, health, ammunition, and other numerical data. Its scanner supports integers, floating-point values, strings, byte arrays, and pointers. Users can modify or freeze memory values, inspect memory regions, and save process memory dumps. An integrated debugger provides instruction disassembly, breakpoints, register inspection, and assembly code modification. Script automation simplifies repetitive memory manipulation and debugging tasks. Bit Slicer also supports document saving, undo and redo, and native macOS window management. It operates using Cocoa and Mach kernel APIs without requiring root privileges.
