downloaded MacOS Big Sur but the installation seems to be taking forever is this normal?
MacBook Pro 13″, macOS 10.13
It may take an hour (or longer if your drive is failing, or is a slow rotational drive). Patience, up to a point, is a virtue with these large multi-GB installations.
Varies.
Had one upgrade to a then-new macOS release some years back require three days.
Apple was interested, but couldn’t reproduce it.
An hour or two for Catalina or Big Sur is fairly typical for a terabyte-scale upgrade on SSD.
An iMac 21.5” with the 8 GB and a HDD config will be slow. Very slow. Did I mention slow?
how long does it take to install
