 - ```CMake Error at tools/xcode-toolchain/CMakeLists.txt:80 (message): Could not identify toolchain dir```
  Make sure you have Xcode installed and ``xcode-select -p`` points to ``/Applications/Xcode.app/Contents/Developer`` instead of the standalone macOS Toolchain

 ## Compilation Issues
 ``fatal error: error in backend: Section too large, can't encode r_address (0x100006a) into 24 bits of scattered relocation entry.`` The obfuscated LLVM IR is way too complicated for proper relocation encoding in MachO, try adjust the obfuscation arguments a bit.

 Or alternatively, you could try using [HikariObfuscator/NatsukoiHanabi](https://github.com/HikariObfuscator/NatsukoiHanabi) which injects the obfuscation code into Apple Clang, this is the least stable implementation but it at least works straight out of the box
