Mac can't update to Big Sur. Is my computer too old?
I own an iMac (21.5-inch, Late 2012) (my mothers computer), and I attempted to update it from Catalina 10.15.7 to Big Sur, but it said update not available. I know my computer is kind of old, so is my computer outdated? Thanks for helping.
iMac 21.5″, macOS 10.15
