    When installing Yosemite I'd like to wipe my mac completely clean and have a fresh install of Yosmite?

    How would I achieve this?

    MacRumors and other sites will provide instructions on how to create a USB install drive to do a clean install once Yosemite is released Thursday after Apple's event.

    Essentially, you'll download Yosemite via the App Store, create a USB install drive by running a script via Terminal, reboot holding the Option key and boot to the USB install drive, delete the partition, rename to whatever you want (stick with Macintosh HD) and install from there.

    I want to do a clean install also. I have time machine backups, can I just do a clean install and then restore my "User" folder? How do I keep my safari favorites and iCloud keychain? (I'm assuming the keychain is actuality stored in iCloud, I just want to be sure.)

    If you have Safari (and calendar, etc.) enabled in iCloud under Settings, then the links are stored in iCloud.

    You can restore your data and stuff from a Time Machine backup. Some app's won't restore correctly from a Time Machine backup (i.e. Photoshop, etc.), so you should re-download them to install them correctly.

    Restoring from backup kind of defeats the purpose of a clean install. You can restore your personal files but don't restore your user Library folder found at {home folder}/Library.

    Is there any tangible benefit to doing a clean install if Mavericks shipped with your machine?

    I'm trying to decide if it's worth my time and the hassle to do a clean install. My computer works fine, except for Flash... and the CPU randomly spikes from time to time due to some kernal operation.

    Depends on your HDD capacity. I have a MBA with 128GB SSD so I'll do a clean install to make sure no junk is left behind taking up room. If you have hundreds of gigs or 1+ TB then you may not care as much.
