Hi,

Just to be clear, when performing a re-installation of MacOS, does this process re-install the same OS, in my case OS Catalina, or will it install the new version MacOS Monterey? I'm looking only to make fresh installation of OS Catalina, i assume then I would be needing to perform a factory reset as opposed to a new installation, or have I got that wrong?

Thanks.

What Mac do you have?
What year was it made?
What was the original OS that came with it?
