Does mac 10. 15.7 have no negative screen?

Mac 10. 15.7 has no negative screen. After installing 10. 15.7 system, the MAC lost a negative screen. In the past, the negative screen could be composed of post-it notes, calendars and other pendants, but now pendants are not supported. NegativeOneScreen, also known as assistant screen, is a function that Apple added to the iOS system. Its function is to display some commonly used applications, shortcut functions, reminders and other contents at the bottom of the mobile phone's main screen, which is convenient for users to access quickly. The negative screen is usually located at the far left of the home screen of the mobile phone. You can enter it by sliding the home screen to the left or clicking the "negative screen" button on the home screen. On the negative screen, users can see different types of cards, such as to-do list, shopping list, travel reminder, weather forecast and so on. These cards can be classified according to users' needs and interests. For example, shopping lists can be classified according to different categories of goods. In addition, the negative screen can also be intelligently reminded according to the user's usage. For example, if the user does not use the mobile phone for a long time, the negative screen will automatically remind the user to close the application running in the background and remind the user to check the local weather when preparing to travel. Corresponding to the negative screen is the home screen, which is the most frequently accessed interface for mobile phone users, including the main applications, contacts, photos, videos and other contents of the mobile phone. Users can enter by sliding the home screen up or clicking the Home button on the home screen. In a word, the negative screen and the home screen are two important functions provided by Apple, which enable users to use their mobile phones more conveniently and quickly, and at the same time provide more abundant channels for mobile phone users to obtain information.
