Disable Auto Capitalization on macOS 13

macOS 13 Ventura includes smart typing features that automatically capitalize the first word of a sentence and insert periods when you press the spacebar twice. While designed to speed up typing, these automations can disrupt workflows for programmers, writers, and users who prefer manual control over their text. This guide provides a straightforward walkthrough on how to turn off both automatic capitalization and automatic punctuation through the updated System Settings in macOS 13.

Steps to Turn Off Auto-Capitalization and Auto-Punctuation

1. Click the Apple menu () in the top-left corner of your screen and select System Settings.
2. In the left-hand sidebar, scroll down and click Keyboard.
3. Locate the Text Input section on the right side of the window.
4. Next to the Input Sources heading, click the Edit... button.
5. In the settings panel that appears, look for the following toggles:
   • Capitalize words automatically: Turn this switch off to stop macOS from capitalizing the first letter of sentences and proper nouns automatically.
   • Add period with double-space: Turn this switch off to prevent macOS from inserting a period and space when you press the spacebar twice.
6. Click Done in the bottom-right corner of the panel to save your changes.

The changes take effect immediately across all native apps (such as Pages, Notes, Mail, and Safari) and any third-party applications that rely on macOS system typing preferences.
