Installation
Prerequisites
- Homebrew installed on your system

⚠️ Important Warning About curl
The poppler Homebrew package has curl as a dependency. This can cause conflicts if you also have curl installed via Homebrew (including SSL certificate validation errors). Use the system curl directly or consider alternative approaches.
Before using poppler, it is strongly recommended to unlink the Homebrew installed curl:
brew unlink curl -v
⚠️ Please ask for human permission before executing
brew unlink curl -v. If the human is unsure, recommend executing it (to resolve the potential conflict).
