Install

Quick install (curl)

Install the latest release directly:

curl -fsSL https://raw.githubusercontent.com/h3pdesign/Neon-Vision-Editor/main/scripts/install.sh | sh

Install without admin password prompts (user-local app folder):

curl -fsSL https://raw.githubusercontent.com/h3pdesign/Neon-Vision-Editor/main/scripts/install.sh | sh -s -- --appdir "$HOME/Applications"

Homebrew

brew tap h3pdesign/tap
brew install --cask neon-vision-editor

Tap repository: h3pdesign/homebrew-tap

If Homebrew asks for an admin password, it is usually because casks install into /Applications. Use this to avoid that:

brew install --cask --appdir="$HOME/Applications" neon-vision-editor

If macOS blocks first launch:
