Upgrade through Recovery Mode:


Two Steps: Backup - then Upgrade...


Important:

Create a Time Machine Backup, then Upgrade:

Prior to the upgrade of your macOS, be certain to backup your Mac using a Time Machine Backup. That way, you can have something to restore your Mac from, should anything go wrong with the upgrade. Use an external hard drive that is at least 1.5 the total storage capacity.


Then...


Upgrade through Recovery Mode: (Hold Down: [Option--R] upon boot) This way, you can upgrade to the latest macOS that is compatible with your Mac. .Go Here: How to Reinstall macOS from macOS Recovery - Apple Support
