Quick Reference - Both Platforms
Two platforms, one launch script
Same ./webui.sh on both sides. The flags and the package managers differ.
| Item | macOS Apple Silicon | Linux (Ubuntu) |
|---|---|---|
| Python version | 3.10 (via Homebrew) | 3.10 (native or PPA) |
| Package manager | Homebrew | apt |
| Key dependencies | cmake, protobuf, rust | libgl1, libglib2.0-0 |
| Launch script | ./webui.sh |
./webui.sh |
| Essential flags | --skip-torch-cuda-test, --no-half-vae |
--xformers (NVIDIA) |
| Access URL | http://127.0.0.1:7860 | http://127.0.0.1:7860 |
| First run time | 10-30 minutes | 10-40 minutes |
Flags you will actually use
| Flag | What it does |
|---|---|
--autolaunch |
Opens a browser when ready |
--medvram |
Cuts VRAM usage if you are running tight |
--lowvram |
Even more aggressive. Slower, but it works |
--listen |
LAN access. Binds to 0.0.0.0 |
--port XXXX |
Use a different port than 7860 |
--api |
REST API for scripting |
--xformers |
Memory-efficient attention. NVIDIA only |
--no-half |
Full precision. Slower, more compatible |
--no-half-vae |
Fixes black or corrupted images |
First run
First launch pulls down about 9 GB of stuff. Go grab a coffee. It will take 10 to 40 minutes depending on your connection.
Models go in models/Stable-diffusion/.
You do not need the brkirch Mac fork anymore. Those optimizations got merged into the main repo.
PNG files remember the recipe
Every image you generate contains the metadata needed to recreate it. The PNG stores the full prompt and negative prompt, the seed number, sampler and steps, CFG scale, model name, and image dimensions.
To reuse settings from any image: go to the PNG Info tab in the WebUI, drag and drop your image (or click to upload), click "Send to txt2img" (or img2img). All parameters auto-populate.
That means you can share images and others can reproduce your exact results. The workflow is self-documenting. No need to keep notes about what settings worked.
Some image editors strip metadata when saving. If you edit in Photoshop or similar, export as PNG and check "preserve metadata" or the equivalent option.
