ProMod

What ProMod is

ProMod manages memory modifications for individual processes on macOS and iOS, with its macOS app optimized for ARM. It can write four-byte ARM instructions into a target process and automatically use code caving for larger patches. Special mods can follow an address in a CPU register and monitor or rewrite float or int32 values according to thresholds. One-instruction mods can use hardware breakpoints without writing to the target app’s memory; the FAQ says a Mac processor allows six at a time. Users can assign mods to keyboard shortcuts with audible cues, including shortcuts that trigger several mods. Portable .pro profiles can be shared with built-in or password encryption. Memory tools include Bytes Diff for scanning changes and Memory Locator for searching hex patterns. Users can enter raw hex or ARM64 assembly, which ProMod assembles, and disassemble surrounding instructions. The macOS app requires an Apple Silicon Mac running macOS 12.0 or later; Intel Macs are unsupported. ProMod Mobile works on non-jailbroken iOS devices but requires injecting libProModMobile.dylib with Sideloadly or a similar tool. The maker describes it for debugging, learning, single-player, and offline use.
