Ok, I've been working on macs for years. What is a 'clean install' vs. the download from Apple?
Clean install - completely wipe and reformat hard drive and
install OS from scratch. Then reinstall apps
and import data.
The download can be used as an upgrade on top of a current installation.
Within the downloaded package (right click see package contents) is the
actual disk image that contains the OS installation. This can be used
to create a stand alone installer (USB memory stick or DVD). This
can then be used to do a clean install.
Why a clean install instead uf upgrade? If you have been upgrading OS's
over the years and also been accumulating apps that aren't being used
and associated drivers perhaps, sometimes doing a clean install is a good
way to start fresh and eliminate the fluff that one can accumulate over
the years. Is this necessary? if a system is well maintained and kept
up to date, it usually isn't necessary.
However, some people just like to have a fresh start with a new OS
to elimate any possible issues with "old stuff".
