Update of OS Yosemite to latest OS mac Big Sur 11.1
I have a macbook pro retina 13 inch, late 2013 model, OS X Yosemite version 10.10.5 currently the system does not show any updates, so how do I update it to the newer version or latest macOS Big Sur 11.1 because the update is not showing in the software update notifications and not even in app store.
