    Hiya all,

    What's the difference between installing Yosemite from a bootable USB and downloading from apple servers

    If you plan to install Yosemite over your existing OS then no material difference other than the installer gets deleted from the applications folder when you download from the MAS and then run the installer.

    If you plan to do a clean install then download Yosemite from the MAS and quit the installer when it auto-runs. You can then create a bootable USB drive which can be used to install the OS.

    It's also a useful backup so you don't have to do another 5GB download if you need to reinstall the OS at a later date.

    In either case you should run a time machine backup before installing the new OS.

    Thanks for the explanation, I have a time machine backup and a bootable usb but when doing a clean install every time it finishes installing Yosemite it starts all over again, I've reinstalled about 3 times already so I thought of trying with downloading via internet recovery, don't mind downloading 5 or 6 gigs again.

    I down loaded the installer to an empty drive then used it to do a fresh install. You get to choose the drive it gets loaded on. Went very well, easiest fresh install in a long time. Other than a lot of apps that still don't have Yosemite capable versions. Small stuff that doesn't bother me but I'm running perhaps 15 fewer apps than I was on 10.8.

    Might help in your case.
