Hacking Marzipan
summary
A full‑blown PDF app (million+ lines, C/C++/Obj‑C/Swift) actually runs on macOS Mojave after hacking Marzipan: using marzipan-platter and marzipan-afire, disabling SIP with csrutil disabled, adding the private iOSMac entitlement, editing the system Swift whitelist, mangling headers, weak‑linking and injecting missing UI classes (e.g. UIWindowToolbarController), and automating packaging with a script. Expect frequent crashes, GPU requirements that break VMs, and fixes for missing frameworks like SafariVC, Photos, and print stacks.
