Tired of macOS constantly changing your input method? InputLock locks your preferred input source and automatically restores it whenever it changes.

Top comment

Hey everyone! 👋 I’m the maker of InputLock. Many of us prefer third-party input methods on macOS — like better Chinese or Japanese IMEs — but macOS keeps switching them back without asking. I got tired of constantly switching back manually, so I built InputLock. It automatically keeps your favorite input method active, no matter what app you’re using or how often macOS tries to change it. It’s lightweight, invisible, and I use it every day myself. I’d love to hear what input methods you use and whether InputLock helps make your workflow smoother. 🙏

Comment highlights

is it just a replacement for the native macOS setting “Automatically switch to a document’s input source”? if this setting is disabled, macOS will not switch the input source. Never.

(Settings → Keyboard → Text Input • Edit → Toggle «Automatically switch to a document’s input source»)

InputLock is a really practical tool—constant input switching on macOS can be surprisingly disruptive. Do you plan to bring this functionality to Windows or Linux as well?

This is awesome! I wish there would be something similar for other parts of MacOS as well to "lock in place". For example microphone. Every time I put on headphones, AirPods randomly decide to take over.

Such a simple yet genius macOS utility. Solves a real annoyance instantly.

Finally! That’s been a quiet pain for years. A simple fix like this will save countless moments of frustration. Does it support per-app input preferences too?
