    I doubt you will recover enough HD space from removing those unwanted programs to make any of this worth while.

    If you really don't want the programs, just drag them to the trash can - no need to reinstall the entire OS.

    Back in the day, I used to do that with OSX (but mostly Windows) but now its not needed.

    The recovery partition is a useful feature of OSX, its needed if you ever want to use FileVault and if you have to recover or reinstall OSX its there to be used, otherwise you'll have to locate the USB thumb drive that will probably get lost.

    Personally for new Macs, turn it on, enjoy the computer and don't worry about reinstalling or removing the recovery partition - just my $.02

    Just do a simple erase of the Macintosh HD partition if you decide to reinstall the OS. But before you do that, make sure you boot the system as shipped so you can register the software licenses in case you ever do decide to use those application.

    Unless something has changed, this doesn't clean up the loops and such for Garage Band and that's a few GBs. The reason to not have programs installed that you don't use is so the system waste time and bandwidth updating them. This of course only applies to applications that are not part of the OS X install.

    It's because 10.9 and 10.9.1 have special builds for the late 2013 macbook pros

    They are not the same builds you get from the mac app store. And this is why your usb isn't working.

    That's why I told you to wait till 10.9.2 is released before making the bootable usb.

    It is likely that when 10.9.2 is released, a usb made for that will boot up your mbp.

    It's not a problem for older compatible computers, just new ones.

    Same thing happened to me in 2011 when I got a 2011 mba with 10.7.

    The 10.7 and 10.7.1 bootable usbs would not boot up the mba because at that time it was too new and the builds for the mba for those were different to the builds on the mac app store.

    Not till 10.7.2 could I make a bootable usb to boot up the mba.

    So provided apple don't make a special build of 10.9.2 for the late 2013 mbp (and we all hope they don't) then a bootable usb made for 10.9.2 will boot up your mbp.

    So I say again, just wait till 10.9.2 is released before making the bootable usb.

    tywebb13 is correct. But you can just command-r boot to recovery and erase Macintosh HD, then click reinstall OS and that will give you a clean install with nothing but Mavericks on there. This will DL the OS from Apple's servers and install it. No need to mess with the USB key.

    oh!! I got it now, thank you, well I wait.

    ----------

    yes I see that "recovery" and I clic and looks like a start for a clean install, my question is, if I reinstall from that he erase my actual sysmtem and install a new one? or install a new one with my files and apps that I previous install? and install iphoto, imovie and all that things that I DONT want? my goal is get a clean install with just the system and "normal" apps.

    If you erase first, then reinstall this way all you will have is the core OS X apps like Safari etc. You will not have iPhoto or iMovie unless you reinstall them from the App Store.

    ok let me see if I understand (sorry for the confusion)

    1. Restart + Option Key
    2. Choose Recovery
    3. Disk Utility for ERASE
    4. Choose in Recovery Reinstall the OS
    5. He start downaloding the system... 5.x gb so take time... later he start installing like always do.

    result: I got my system clean with NO iphoto, imovie etc...

    that is?

    Yes, exactly. Or you can skip 1 + 2 by holding command-r at boot and that will take you straight to recovery.

    thanks! OR! let me see if I can do this too:

    1. I go to Recovery
    2. Disk Utility > Erase
    3. I boot from the USB KEY (that I already had with the mavericks boot downladed from app store) and install the system.

    so I skip download the system again!

    is possible?

    my question is if this usb key maverciks that I download from app store content iphoto and that things, I think NO that is clean, but I just ask...

    That won't work because the App Store version you made the USB key with is not the same build number as the one recovery will download from Apple's servers. You will need to download from recovery like I described.

    The recovery method installs the original system that came on your computer, which is a different build than the one from the mac app store.

    I think it would still be worth making a bootable usb of 10.9.2 when it is released though.

    The recovery method will not let you keep the installer.

    You can intercept the recovery installer using this convoluted process if you are intent on getting it. I have read forum posts from others saying this still works with Mavs.

    Yeah. But that has to be modified for mavericks because the InstallESD.dmg isn't bootable for mavericks.

    alek2407 figured out a way to do it for mavericks here:

    It's very tricky and so I'd be more inclined to wait for 10.9.2 to be released before making the bootable usb.

    It looks like Alek is grabbing the DMG exactly the same way. All that is different that I can see is how to make the USB key afterwards.

    I agree it is a pain, and I would not even bother either. But it can be done.
