I can't download Microsoft Remote Desktop because I don't have the right macOS

If you cannot download Microsoft Remote Desktop because you are getting a warning that your Mac needs to run a newer version of macOS, you have the following options:

• See if Microsoft still provides a version of Remote Desktop that runs on your macOS version.
• Upgrade macOS on your MacBook Air.
• Use an alternative remote desktop app that is supported with the version of macOS your notebook is running.

• What is the version of your macOS?
• Upgrade if any macOS Software Updates are available.
• reinstall the Microsoft Remote Desktop.

Drag the app from the Applications folder into the Dock. It'll remain there for easy access and launching.
