Tools used to alter or measure the segment sizes of Mach-O binaries. Why Developers Use CCTools 65 Today

While cc65 is a dominant tool for 6502 development, it's worth knowing how it fits into the broader "cctools" landscape: cctools 65

While modern macOS systems lean heavily on LLVM/Clang and updated iterations of the ld64 linker, older software baselines, reverse-engineering suites, and cross-compilation toolchains for retro-computing frequently target older explicit builds like cctools-65 variants. Developers maintaining vintage open-source repositories or working on absolute cross-compiler compatibility for legacy systems use these targeted builds to prevent modern compiler optimizations from breaking outdated software architectures.

Apple uses the Mach-O (Mach Object) file format for executables, libraries, and object code. cctools 65 provides pure, unbloated implementations of tools like otool and ld optimized for classic 32-bit architectures (like ARMv6 used in the iPhone 2G/3G) and PowerPC/Intel x86 binaries.

The most widespread meaning of cctools in modern computing refers to Apple's collection of low-level binary tools for the Darwin operating system (the core of macOS, iOS, watchOS, and tvOS). Think of them as the macOS equivalent of the GNU binutils (like ld , as , ar ) found on Linux.
