What is symbol rebasing and binding in Mach-O loading?
Updated May 17, 2026
Short answer
Rebasing adjusts pointers; binding resolves external symbols during loading.
Deep explanation
Rebasing fixes internal pointer addresses when ASLR shifts memory. Binding resolves references to external dylibs. Both happen during dyld loading phase.
