Cctools - 65

If you are looking for a deep dive into cctools 65, you are likely referring to the Apple open-source toolchain (like nm, otool, and ld64) or perhaps its relationship with the cc65 compiler suite for 6502-based systems.

• Understanding Mach-O internals
• Maintaining legacy macOS/iOS build systems
• Porting Apple tooling to non-Apple platforms (via cctools-port)

What’s New

• ld64 improvements: Faster link times for large projects with -dead_strip and -no_deduplicate.
• ARM64e support: Fixed pointer authentication (PAC) stability in static archives.
• strip: Resolved symbol table corruption when stripping debug info from bitcode‑enabled objects.
• otool: Now correctly displays LC_FILESET_ENTRY load commands.
• install_name_tool: Added -delete_rpath for safer removal of runpaths.

For those working on OpenStep or early versions of Mac OS X, CCTools 65 is often the necessary bridge to compile modern utilities for older hardware. How to Access and Build CCTools 65 cctools 65
