> Every way to switch keyboard layouts on macOS

Most wrong-layout typos happen right after switching apps or windows, when you forget which input source is active. Picking a switching method that fits your hands reduces them. These are the options built into macOS Sonoma and later.

> 1. Add both input sources

Open System Settings → Keyboard → Text Input → Input Sources → Edit. Click “+”, choose Russian and pick either “Russian” (Mac) or “Russian – PC”. The letters are identical; punctuation keys differ. Russian – PC matches Windows keyboards, which helps if you use both systems.

> 2. Control-Space

The default shortcut. Control-Space switches to the previously used source; Control-Option-Space cycles through all of them. You can change these in System Settings → Keyboard → Keyboard Shortcuts → Input Sources.

> 3. The Globe (fn) key

On Apple keyboards with a Globe key, set System Settings → Keyboard → “Press 🌐 key to” → Change Input Source. One press switches layouts.

> 4. Caps Lock

In the Input Sources editor, enable “Use the Caps Lock key to switch to and from ABC” (the label may name U.S. instead of ABC). A short press switches layout; holding it still toggles caps. Many bilingual typists find this the fastest option.

> 5. The menu bar

Enable “Show Input menu in menu bar” to see the active source as a flag or letters. It is a good visual check, but it is easy to miss while typing.

> When switching is not enough

macOS can remember the input source per document (“Automatically switch to a document's input source”), which helps in some workflows and confuses in others. Whatever you choose, some typos will still happen — that is the gap TextSwitcher fills by correcting the finished word automatically.
