You will not find exact Notepad that you get on Microsoft Windows OS. But you will get TextEdit.app on Mac OS. It is somewhat like Notepad on Windows OS but somewhat different. To open TextEdit on Mac, go to Finder Button, click on Applications, and then click on TextEdit.app. You left click one and drag to Desktop to keep it on Desktop for shortcut. You can bold, italic, underline, align text to the left, right, centre, you can colour text also. You can use TextEdit like MS Word. You can choose the font family as well.
