Bit Slicer review
A deep, open-source macOS memory editor for debugging, modding, and testing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Bit Slicer is an open-source macOS application for searching, inspecting, and modifying live process memory. It is aimed at game modders, reverse-engineering hobbyists, and software testers who need more than basic value scanning. Searches cover integers, floating-point values, strings, byte arrays, and pointers, while variable freezing, process pausing, memory dumps, and saved search documents support repeated investigation.
Its strongest distinction is the depth of its memory and debugger workflow. Multi-level pointer searching and pointer-path manipulation help trace changing addresses, while a hex-editor-style window provides live viewing and editing. The debugger adds instruction disassembly, assembly, breakpoints, stepping, register access, backtraces, code injection, and the ability to watch instructions that access variables. Memory protection attributes can also be modified. These capabilities make Bit Slicer suitable for users who need to understand how a process behaves, not just change a visible value.
Python scripting extends the tool into repeatable automation for virtual-memory and debugger operations, and undo or redo support helps manage edits. The published release information supports both ARM and Intel debugger modes, with the current release requiring macOS 11.5 or newer. Bit Slicer is a strong choice for Mac users who want an open-source tool combining scanning, editing, pointer work, debugging, and scripting. Users needing Windows or Linux support, or a simpler trainer focused only on quick value changes, should choose a different tool.
