Good news! You can upgrade to macOS Big Sur! Big Sur will be a huge upgrade for your Mac that will include the latest features and built-in apps compatible with your Mac.

Choose Big Sur 11 from this Apple Support page: How to download macOS - Apple Support.

Before installing, it’s a good idea to back up your Mac. While installing, avoid putting your Mac to sleep or closing its lid. Your Mac will restart, and it might show a progress bar or blank screen several times.
