    I'm following this guide here:

    How long does it take roughly to erase the disk and reinstall OSX?

    This will bring the computer back to its original purchase state?

    Also, is a wired connection okay or does it have to be wireless?

    Thanks! :)

    Depends on what kind of Mac you have and method of install. Typically, if you have a stock 5400 rpm drive, it takes about 30 - 45 minutes using a USB installer. If you are using the internet recovery route, it can take over an hour, depending on speed of internet etc. If you have a SSD using a USB installer, it typically takes 15 minutes or so. It takes about 45 minutes or so via internet recovery.

    The length of time it takes depends on many factors, such as your internet and hard drive speeds.

    Yes, a clean install will put it into a similar state as when it was new.

    Wired will work fine.
