Understanding PwnDFU on Mac: A Technical Overview is a "hacked" version of the standard Apple Device Firmware Update (DFU) mode. While standard DFU mode is used for restores and troubleshooting, PwnDFU leverages low-level vulnerabilities—most notably the checkm8 bootrom exploit—to bypass signature checks. This allows security researchers and enthusiasts to load custom ramdisks, downgrade firmware without SHSH blobs, and perform deep system modifications on older iOS devices. Core Tools for Mac Users
