macOS 10.16 Monterey launched on October 25, 2021. Should I install yet?
The general rule is to give a new release at least a month before using. This gives Apple some time to fix any possible bugs.
More importantly, why do you need to upgrade (unless you are running Mojave or earlier)
Be careful, make a full time-machine backup and make sure your computer is compatible, has enough free disk space and is NOT running a conventional HDD (Hard-disk-drive) …as an update such as this will likely kill the HDD.
