    I am waiting for my new iMac to arrive and while reading some of the threads here on the forum, I see a lot of people recommending to do a clean install of OSX when getting a brand new machine.

    The reason is that it should "cure" some problems that can be with and make it faster.

    How do I do that?
    Should I use the recovery partition or something else?

    Yes... you can command-r to recovery and erase the disk then reinstall. But just confirm, this is a new machine that you will not be importing any data to? If so a clean install is a complete waste of time.

    The idea of a clean install is to get rid of old, leftover files that may have accumulated over time. But if your machine is new, there will be no old files or old incompatible utilities or anything to get rid of, so there is no need to do a clean install.
