CursorTint — A Small macOS App That Makes Terminal Input Less Frustrating

Description and use

CursorTint is a lightweight macOS app that changes the Terminal cursor color to indicate the active input method, helping users avoid typing commands in the wrong mode.

Problem

The author frequently typed commands in macOS Terminal while the Japanese input method was active, causing accidental command execution and frustration.

Outcome

CursorTint provides a lightweight, zero‑configuration solution that reduces input‑mode errors in Terminal by visually indicating the active input source through cursor color changes.

Workflow

• Launch CursorTint from the menu bar.
• Use existing keyboard shortcuts to switch input methods as usual.
• Observe the cursor color change in Terminal: gray for English, red for Japanese or other non‑U.S. sources.
• Continue typing commands knowing the current input mode.
• Quit CursorTint from the menu bar to restore the original cursor color.

Evidence

I built CursorTint, a small, free, open-source macOS app that helps you avoid typing commands in the wrong input mode.

When the input source is anything other than U.S., ABC, or ABC Extended, the cursor turns red (#EB5F5F).

There's no configuration required. Just launch the app, and it works with your existing input-switching shortcuts.
