# List all installed casks
brew list --cask⚠️ Why direct download is not recommended (Click to expand)
This app is not signed with an Apple Developer ID (costs $99/year). When you download directly from GitHub:
- ❌ macOS will block the app with "app is damaged" error
⚠️ You must manually remove quarantine attribute⚠️ Extra terminal commands required⚠️ More steps and potential security warnings
We strongly recommend using Homebrew instead, which handles all of this automatically.
If you still want to download directly, visit the Releases page:
Download palet-ai-macOS-arm64.zip
- Unzip the downloaded file
⚠️ REQUIRED - Run this command in Terminal:xattr -cr ~/Downloads/Palet\ AI.app
- Drag
Palet AI.appto your Applications folder - Double-click to open
Why is this needed? Without Apple Developer code signing, macOS marks downloaded apps as "quarantined". The
xattrcommand removes this flag. Homebrew does this automatically.
