Open Settings: Windows vs Mac
On Windows, the Windows key + I opens the Settings app directly. macOS has no single key for System Settings, but Cmd+comma (⌘,) opens the settings/preferences of whatever app you are in — the most-used settings shortcut on a Mac.
| Action | Mac | Windows | |
|---|---|---|---|
| Open system settings | menu › System Settings (no default key) | ⊞+I | |
| Open the current app's settings | ⌘+, (comma) | varies (often Ctrl+, or via menu) | |
| Search settings | ⌘+Space, type the setting | ⊞+I, then search box |
The direct answer
On Windows, ⊞ Win + I opens the Settings app instantly from anywhere.
Mac: Cmd+comma, not a global key
macOS has no built-in keystroke for System Settings — you open it from the Apple menu. But every Mac app uses ⌘ + , (comma) to open that app's settings, which is the shortcut Mac users reach for daily.
Jumping to a specific setting
Fastest route on either platform: search. On Windows press ⊞+I and type in the Settings search box; on a Mac press ⌘+Space (Spotlight) and type the setting name to jump straight to the right System Settings pane.
