Bit Slicer

What it is
Bit Slicer is a free, open-source game trainer for macOS that searches for and changes values such as scores, lives and ammunition. Its scanner handles integers, floating-point values, strings, byte arrays and pointers, and can narrow search results. Users can inspect and edit live memory in a hex-editor-style window, dump memory to disk and alter memory-protection attributes. Debugging tools include instruction-access watches, live disassembly, breakpoints, backtraces, register manipulation and stepping, as well as byte or assembled-instruction changes. The app can inject assembly code into a running process, and scripts can automate virtual-memory and debugger methods. Saved Slice documents can be shared. The project says it can run as a normal user rather than root. Version 1.9.2 is listed as the latest release. The current release requires macOS 11.5 or newer, although the freeware plan lists macOS 10.8 or later. Support is directed to the wiki and Discord, and is not available 24/7.
