The tilde symbol (~) is a small wavy like that appears over some consonants and vowels. You’re likely to find the tilde above letters in the Spanish and Portuguese languages. Modern keyboards only contain a limited number of symbols and the tide symbol isn’t part of your keyboard.
If you want to type the tilde symbol over a word on your mac, then you can use code. The tilde marks are commonly used over uppercase and lowercase constants and vowels such as Ã, ã, Ñ, ñ, Õ, and õ.
Typing Tilde Over Letter on Mac
If you want to type tilde over a letter on Mac, hold the Option key and press the letter N, then release both keys. A tilde will then appear above an underscored blank space. Type the letter you want to tilde over, e.g. A, N or O to create lowercase letters. For uppercase letters with the tilde over, press Shift and type the letter you want the tilde over.

If you want to type the tilde alone without typing a letter underneath, you can use the Character map on your Mac.
