Even with the right tools, things go wrong. Here are the most frequent problems and solutions.

Step 1: Extracting the RAR File (Mac & Windows)

To get the files out of the RAR container, you need an extraction tool. Do not use the built-in macOS Archive Utility (it fails on multi-part RARs).

Recommended Tools:

The Unarchiver (Free, Best for Mac) – Handles RAR, 7z, and virtually everything else.
Keka (Free/Open Source) – Modern Mac interface.
WinRAR (Windows) – The original.
7-Zip (Windows/Linux) – Command-line friendly.

How to extract (Mac - The Unarchiver):

Download and install The Unarchiver from the Mac App Store.
Locate all the .rar files (e.g., game.part1.rar, game.part2.rar).
Right-click on game.part1.rar → Open With → The Unarchiver.
The app will automatically locate the other parts and extract the full contents into a new folder.

How to extract (Command Line - Terminal): If you have Homebrew installed, you can use unar:

brew install unar
unar myfile.rar

Error 4: Permissions issues after PKG installation

Cause: When you used pkgbuild, you forgot to set proper permissions on the extracted files before building.
Fix: In Terminal, run chmod -R 755 /path/to/extracted/folder to ensure executables run correctly, then build the PKG.

Error 2: “Unsupported compression method” in RAR extractor

Cause: The RAR file uses RAR5 compression (newer standard), and your extractor is ancient.
Fix: Update to The Unarchiver (v4.0+) or Keka. WinRAR 5.0+ also handles this.
