Section 2: Preparing for Installation
To ensure a smooth installation, it’s important to prepare your PC. Taking a few simple steps beforehand can save time and prevent headaches later.
- Back Up Important Data: While installing ComfyUI should not affect your files, it’s always wise to back up important data. You can use built-in backup tools like Windows Backup, Time Machine on macOS, or third-party solutions like Acronis or Backblaze.

This can help prevent compatibility issues during installation. On Windows, go to Settings > Update & Security > Windows Update. For macOS, go to System Preferences > Software Update. On Linux, use your package manager (e.g., sudo apt update && sudo apt upgrade).
- Disable Antivirus Software Temporarily: Some antivirus programs can mistakenly flag new installers as malicious. Temporarily disable real-time protection or create an exception for the ComfyUI installer file to prevent interference.
