Mac 用户终于有救了！这可能是今年最让我相见恨晚的 Mac 工具。

有没有被输入法逼疯过？

明明切到英文准备敲代码，下一秒又莫名变回中文； 打开 ChatGPT 是英文，切到微信要中文，来回切几十次； 更离谱的是，有些软件还会偷偷帮你切输入法…… 今天发现一个免费开源神器：LockIME。 它能直接「锁死」你的输入法！

全局锁定输入法 不同 App 自动使用不同输入法 浏览器不同网站自动切换输入法 24 小时切换记录可查 快捷键一键控制 体积不到 3MB

简单说： 微信永远中文， Cursor 永远英文， 浏览器某些网站自动英文， 再也不用手动切换输入法。 最关键的是： 完全免费！ 完全开源！ Mac 用户必装级神器！ 用过之后最大的感受： 不是效率提升了多少，而是每天少生无数次气…… GitHub： https://github.com/oomol-lab/LockIME…

LockIME

English · 简体中文 · 繁體中文 · 日本語 · Français · Deutsch · Español · Português · Русский

A macOS menu-bar app that locks your keyboard input source. Whenever you (or another app) switch input methods, LockIME immediately switches back to the locked one — globally, or per-frontmost-app, or (with the optional enhanced mode) per browser URL.

macOS 14+ · Apple silicon & Intel — separate apps, download the -arm64 or -x86_64 file matching your Mac · built with SwiftUI, Liquid Glass on macOS 26 (Tahoe).

Install

Install with Homebrew (the cask picks the build matching your Mac’s architecture):

brew install --cask oomol-lab/tap/lockime

Or download the .dmg matching your Mac (-arm64 for Apple silicon, -x86_64 for Intel) from the latest release. Either way, the app keeps itself up to date via Sparkle.

Features

• Instant re-lock — switches the active input source back the moment you (or another app) change it, globally or per-app.
• Lock or switch — per-app and per-URL rules can lock an input source (re-applied whenever it drifts) or just switch to it once when you focus the app or page, then step out of the way and let you change it freely.
• Flexible URL matching — per-URL rules (enhanced mode) match by a domain and its subdomains, an exact domain, a domain keyword, or a regular expression over the full URL, and apply in a priority order you drag to arrange — first match wins.
• Menu-bar control — activate/deactivate, switch the locked input source, view the current source, and track the activation count from the menu bar.
• Keyboard shortcuts — configurable global shortcuts to toggle locking and cycle the locked input source, plus per-app shortcuts to cycle or unbind the rule for whichever app is frontmost.
• Launch at login — starts automatically when you log in (off by default).
• Light & dark mode — a unified, system-native design language that adapts to light and dark appearance, plus a bespoke app icon. See docs/DESIGN.md.
• Live language switching — switch between 9 languages instantly, no restart: English, 简体中文, 繁體中文, 日本語, Français, Deutsch, Español, Português, Русский.
• 24-hour activation log — review what was switched, why, and for how long.
• Config backup — export your per-app and per-URL rules to a .lockime file and import them back, with a review step that previews additions, conflicts, and removals before anything is applied.
• Auto-update — stable and beta channels via Sparkle, with a custom update window.
• Tiny download — the whole app ships in a .dmg under 3 MB.
• No system permissions for core locking — an optional Accessibility-gated enhanced mode unlocks finer-grained per-URL and focused-field rules.
• Automation — a lockime:// URL scheme lets other apps, scripts, and Shortcuts drive LockIME (see below).

Automation

LockIME exposes a lockime:// URL scheme so other apps, scripts, Shortcuts, and launchers can drive it — toggle locking, retarget the input source, manage rules, and read state back with x-callback-url callbacks. It is off by default — turn it on in Settings ▸ General ▸ Automation.

open "lockime://lock"
open "lockime://lock-to-source?id=com.apple.keylayout.ABC"
open "lockime://set-app-rule?bundle=com.apple.Terminal&mode=lock&source=com.apple.keylayout.ABC"

Full reference: URL Scheme API.

Design

LockIME follows a single design system (Sources/LockIME/UI/DesignSystem.swift): semantic colors, system materials, and SF Symbols drive light/dark adaptation; Liquid Glass is reserved for the floating/navigation layer only. The brand “Lock Indigo” accent ships as an AccentColor asset. The full spec lives in docs/DESIGN.md.

The app icon is generated programmatically (no design tool) — regenerate it with:

./scripts/make-appicon.sh   # renders the master via SwiftUI and rebuilds the appiconset

Development

Requires Xcode 26+ (the app itself targets macOS 14+), and XcodeGen

• xcbeautify (brew install xcodegen xcbeautify).

make gen     # generate LockIME.xcodeproj from project.yml
make build   # build (Debug)
make run     # build & launch
make test    # run unit tests
make archive # Release archive (Developer ID)

The Xcode project is generated from project.yml and is not checked in.

Hardware-touching integration tests (real TIS switching) are excluded from make test; run them with make test-hw (briefly changes the input source).

Releasing

Dispatch-driven, notarized Developer ID releases with Sparkle auto-update over stable and beta channels: run the Release workflow (Actions → Release) and it computes the version from git tags, builds, and creates the tag and GitHub Release automatically — never push a tag by hand. The beta channel is the nightly build. Every release ships separate Apple-silicon and Intel apps, each on its own update feed (no universal binary, no cross-arch updates). See docs/RELEASING.md.

Architecture

• LockIMEKit (static library) — pure, fully unit-tested logic using only system frameworks: lock engine, app monitor, rules, enhanced (Accessibility) observer, logging model, localization.
• LockIME (app) — @main, SwiftUI UI, the design system, and the thin integration shims for Sparkle, KeyboardShortcuts, and PermissionFlow.
