 ## macOS
 
+Install LLVM 12 and homebrew dependencies:
+
+```bash
+brew install llvm@12 coreutils libtool cmake libiconv automake openssl@1.1
+```
+
+You will also need esbuild (used for bundling internal library code until Bun has better support for bundling libraries):
+
+```bash
+npm install -g esbuild
+```

 Compile Zig:
 
 ```bash
 git clone https://github.com/jarred-sumner/zig
 cd zig
 git checkout jarred/zig-sloppy-with-small-structs
-cmake . -DCMAKE_PREFIX_PATH=$(brew --prefix llvm) -DZIG_STATIC_LLVM=ON -DCMAKE_BUILD_TYPE=Release && make -j 16
+cmake . -DCMAKE_PREFIX_PATH=$(brew --prefix llvm@12) -DZIG_STATIC_LLVM=ON -DCMAKE_BUILD_TYPE=Release && make -j 16
 ```
