High Sierra to Big Sur upgrade
Trying to upgrade my MacBook Pro from High Sierra to Big Sur. Have an early 2015 MacBook Pro (Retina) 10.13.6 which Apple says is eligible. About this Mac shows I have 40.98 GB available and only needs 35GB for the upgrade. Yet, when I go to upgrade it says not enough memory. Any thoughts on why?
