To create a Skype account on a Mac, download the Skype program from skype.com using a web browser like Safari. Once the download is complete, open the file and copy the Skype icon to the Applications folder. Launch Skype and enter your contact number, email address, and a password to set up an account. Provide verification of your identity and choose a theme to personalize your window. Skype will then give you a tutorial to learn about its features and menus before you can start using your new account.
