Manually changing a whole paragraph of text from lowercase to uppercase letters is hardly productive use of anyone's time. Mac computers include a feature that can do this automatically for you without the need to download additional software. You can change any text to uppercase or lowercase, as well as capitalize the first letter of every word if needed. Because this feature is part of the Mac OS X operating system, it works on most Apple programs like TextEdit, Notepad and even Stickies. If you need to change the text where this feature isn't supported, like the text field in a Web browser, just copy the text, paste it into TextEdit to transform it and then paste it back where you need it.

Highlight the text you want to change in an application like TextEdit or Notes by dragging the cursor over the text.

Hold down the "Control" key on the keyboard and click the highlighted text. If you have a two-button mouse, you can right-click instead. Select "Transformations" from the drop-down menu.

Select "Make Upper Case" to change the text to all upper case letters. Select "Capitalize" to capitalize the first letter of each word. You can also choose "Make Lower Case" to change all letters to lower case.
