Big Sur Won’t Install

MacBook Pro (13”, 2018, 4 Thunderbolt 3 Ports) using High Sierra 10.13.6


Downloaded macOS Big Sur with plenty of space remaining.


When selecting the disk where I want to install it, I get a pop-up, “The volume is not compatible with this update” even though my model is on Apple’s published compatible list for Big Sur.


What am I missing? Thanks in advance!

Verify from About the Mac the model/date of this machine?

Did you try booting to SafeBoot Mode, log-in and then launch your macOS installer...
