⚡ Mega SDXL v1.6 Update — New Installer, Mac Support, Fixes

Edit (Aug 17): Big installer refresh. It’s now more robust, cleaner, and cross-platform.

• Updated the installer to my new standards. It’s now better in every way.

• Fixed Reactor nodes being persistently missing.

  • InsightFace now installs correctly (no more missing reactor nodes).

• Added Mac support with simple terminal steps.

👉 If you ran any earlier version, run this one too. It won’t redownload files you already have.

Previous Updates (May 24)

• Added two models for Face Swap and Face Restore to installer

• Fixed missing note nodes in the workflow

• Various tweaks and fixes

🖥️ Step 1: Download ComfyUI (Desktop Version)

👉 ComfyUI Desktop

🧰 Step 2: Load the Mega Workflow

Download the Mega Workflow json file (bottom of this post).

• Drag and drop into ComfyUI

• It will give a popup if you are missing nodes

  • Click Open Manager → Install missing custom nodes

  • My nodes will remain missing, the installer will handle that

If the workflow looks empty, hit period key on your numpad to frame all nodes into view

🚀 Step 3: Run the Auto Installer

Download the Launch_Mega_SDXL_Installer.bat and mega_sdxl_installer.py at the bottom of this post. (If you are on mac or linux, see below)

💻 Mac Installation

• Download only mega_sdxl_installer.py and place it in your ComfyUI directory.

  Then:

  1. Open Terminal

  2. Type cd (with a space), then drag and drop the ComfyUI folder into the Terminal window, and press Enter

  3. Run the installer:

.venv/bin/python mega_sdxl_installer.py

✅ It’ll ask a few setup questions and handle the rest.

⚠️ If you get a permission error, run:

chmod +x mega_sdxl_installer.py

Then try again.

🔨 Improvements & Fixes in v1.5

• Face swap, face restore, and image blending groups are included (Mega version only)

• Workflows now use the new v1.5 layout with no hidden nodes, exposed wiring, and cheat sheet notes

• Inpainting has been improved

• Various custom node fixes and improvements

💡 Heads Up

Windows Defender might freak out. That’s normal for unsigned apps.
Just click "More info" → "Run anyway"
(You just saved me over $100 🫡)

🧠 Why learn ComfyUI?

That's what v1.5 tries to make easier. What's the point?

• Learning ComfyUI gives you:

  • Full control over your workflow layout and style

  • The power to chain things together (e.g. text to image → adetailer → upscale)

  • Mix and match techniques that typically aren't

  • Actually understand how ComfyUI is working

A lot of people hate ComfyUI because they misunderstand it and give up. This workflow is built so that doesn’t happen to you and puts you a mile ahead of the ones who bailed. 🫡

🌐 Get Extra Models

These aren't in the installer, why?

The installer has my own model (Hyper3D) and another for realism from the v1 installer.
This time, I wanted to set you up to start grabbing your own models because that's a core part of using ComfyUI long-term.

Here are a couple worth trying:

• Pony Diffusion v6 – Anime

• CyberRealistic XL – Realism

💾 To install them manually:

• Place the safetensors files into ComfyUI/models/checkpoints/

I recommend checking out Civitai as that is where you will find great models and loras.

Random side note: absolutely remove "score_9, score_8_up... etc) from prompts if you aren't using Hyper3D. They can heavily affect the resulting image if the model wasn't trained on them.
