In recent updates to the Mac OS, Apple added features to their desktop OS that were previously available only on iOS devices. These new features delivered a more unified user experience across all Apple platforms and have been generally well received by users.
However, a few of these newly added features are less than ideal and have been causing some users headaches. For example, you may have noticed that when you type an email or text message a period (.) is automatically appended to the end of the line you just wrote. This happens whenever you press the space bar twice. It’s supposed to offer convenience, but instead caused confusion and frustration for some users.
In this post I will show you how to disable this feature, i.e., how to stop your Mac from annoyingly adding an unwanted period to your text.
To disable this feature, go to System Preferences -> Keyboard -> Text, and de-select “Add period with double-space”, as shown below.

Happy hacking 🙂
