Copy & Newline Not Working in macOS Default Terminal #12003
Description
Description
When running OpenCode in macOS Default Terminal.app, I’m unable to:
- Copy selected text
- Insert a new line while typing prompts
This makes OpenCode nearly unusable in interactive mode.
Environment
- OS: macOS (Sonoma / Ventura – reproducible on default Terminal.app)
- Terminal: macOS Terminal.app (default)
- Shell: zsh
- OpenCode Version: latest
- Node Version:
node -v - Installation: CLI (
opencode)
Steps to Reproduce
- Open Terminal.app
- Run
opencode - Try selecting text and copying (Cmd + C or right-click)
- Try inserting a new line while typing a prompt (Enter / Cmd+Enter)
Expected Behavior
- Text selection should be copyable using Cmd + C
- Enter should create a new line in the editor (or documented keybinding)
Actual Behavior
- Copy does not work
- Enter submits instead of inserting a new line
- No way to insert multi-line prompts in Terminal.app
Additional Notes
-
This appears to be a terminal input handling issue
-
Likely related to:
- raw mode / TTY handling
- readline / ink / blessed-style input
-
Works better (or differently) in iTerm2 (needs confirmation)
Impact
High — makes OpenCode difficult to use on macOS without switching terminals.

Enter is meant to submit the prompt, shift+enter usually does newline. Terminal.app does not support shift+enter detection though. Option+enter might work. Selected text is automatically copied, there is no shortcut for it, unless you use native terminal selection.
Opencode has nothing to do with node, it uses Bun.

For what it's worth, if for whatever reason copy on select isn't working in OpenCode, try holding shift while you select text.
(Most terminals support this, holding shift will make it so you have "normal" terminal selection instead of it being controlled by the TUI)

The "Copy to Clipboard" functionality isn't working on Ghostty either. This just started with the latest version. It says "Copied to clipboard" toward the top-right, but nothing gets copied to the clipboard.

Clipboard issue seems to be fixed in 1.1.51, using Ghostty + tmux w/macOS 26.
