ipsw

Use this skill when reverse-engineering Apple platforms with the ipsw CLI — analyzing iOS/macOS Mach-O binaries, disassembling functions inside dyld_shared_cache (DSC), dumping Objective-C/Swift headers from private frameworks, extracting kernelcaches, KEXTs, SEP, iBoot, or DeviceTree from IPSWs/OTAs, decompiling/querying sandbox profiles (SBPL), querying entitlements, symbolicating crashes/panics, diffing two firmware versions, mounting IPSW DMGs, or downloading Apple firmware. Triggers on iOS/macOS internals, kernel research, dyld_shared_cache, KEXT diffing, sandbox/Seatbelt profile analysis (SBPL/SBASM/sandboxd), capability/IOKit queries, entitlement lookup, class-dump, IMG4/AEA handling, or vulnerability research on Apple platforms.
