- Initiate Software Update:
- From the Apple menu located in the corner of your screen, select System Settings. In the ensuing window, click on General in the sidebar, followed by Software Update on the right. (For earlier versions of macOS, select Apple menu > System Preferences, and then click Software Update.)
- Alternatively, you may utilize Spotlight to search for “Software Update,” and subsequently click to open it from the search results.
- If your Mac does not feature Software Update, please refer to other methods for downloading and installing macOS.
- Upon the opening of Software Update, it will automatically check for any available new software. If new software is present for your Mac, click the Update or Upgrade button to download and install it.
- In the absence of new software for your Mac, Software Update will indicate that your Mac is current. Should you wish to conduct another check, click Check for Update (if available), press Command-R on your keyboard, or close and reopen Software Update.
- Prior to the commencement of installation, you will be prompted to enter your administrator password, which is the password you utilize to log in to your Mac. Have you forgotten your password?
- Please allow the installation to complete without putting your Mac to sleep or closing its lid. During the installation process, your Mac may restart and display a progress bar or a blank screen multiple times.
