When a new version of OX comes out i do a clean installation and never upgrade the installed one.

 

How can i do this since Apple will sell it only via App Store?

 

Thank you,

Paulo.

    Right now, the only option Apple has officially announced for installing Lion is via a download from the App Store.  There are many instances where someone might want/need to do a fresh install.  Until Lion is actually released, or Apple indicates otherwise, we don't know of any other installation options.

    Erase and install Snow Leopard.
    If your machine came with 10.6.5 or earlier, apply the 10.6.6 combo update.
    Install Lion.
    That should work nearly as good as an erase and install of Lion if Apple ever provided such an option.
    The only time you would want to erase and install an operating system is to identify issues with hardware quickly, and when you have at least two separate backups from your machine.  Of course if you are replacing a hard drive, you erase and install then too.

    Personally, I look at your procedure to upgrade OS X as a total waste of time.

     

    In all of the years, I have been using OS X, I have yet to do an erase & install.

     

    Generally immediately after doing the erase & install, the next step is to restore all of your files from the backup. Most of the corruption is usually there so that you are basically in the same condition as it you would have done a simple upgrade.

    Your reply wasn't clear. Will i have the option to do a Fresh & Clean installation?

    "Erase and install Snow Leopard and then Lion" is not what i look. Thanks.

    Great if you have that much time to waste.

     

    Then you are going to have to wait for Lion to be released to see what the alternative are.

     

    With what has been released so far it appears that it will be much more convoluted that anything in the past seeing as how it will only be released on the App Store.

     

    Way back when OS X was first released, there may have been some justification for the Erase & Install. Any more, Apple has improved the install process to the point where the Erase & Install has lost the vast majority of its usefulness. In fact the latest install procedure with in fact replace the complete OS on a reinstall now.

    "Erase and install" is Apple's terminology for totally wiping the hard drive, then installing the operating system as is.  The last time "clean install" was used by Apple was in Mac OS 9.  Then it referred to renaming the System Folder, and creating a new one in its place.  Between 10.2 and 10.5 Apple created a similar process known as Archive and Install, as well having an "Erase and install" and install option on the installer disc, as well as an Upgrade and install which just updated the operating system from what it was without changing the System folder.

     

    Snow Leopard condensed it all to two different install options.  The one on the installer simply replaced the System folder, with one functional for the operating system chosen.  When downgrading this left behind applications too new for the operating system.  An erase and install was documented in the support notes, as erasing from Disk Utility, then installing from the DVD the operating system.

     

    Lion just has one option that we are aware of, and that's updating a 10.6.6 or 10.6.7 installed system. Until it is released it is unknown if imaging, or cloning to another hard drive will work as expected, or if it will work within licensing restrictions.

    Its only a waste of time if the user deems it as such. I enjoy going on motorcycle rides, but some people I know think it's a waste of time...

    "...Erase and install is Apple's terminology for totally wiping the hard drive, then installing the operating system as is..."

     

    It is exactly what i am looking for "totally wiping the hard drive, then installing the operating system". Will this be available in Lion?

     

    Thank You.

    Yes, it will be available in Lion.

  • a brody Level 9 Level 9 (63,895 points)

    Lynsix, How do you know?  Based on prevailing information, it looks like:

     

    1. You can Erase and install Snow Leopard, install the 10.6.6 or 10.6.7 combo update (this combo update only would be necessary if your Mac is older than 10.6.6), and then upgrade to Lion

     

    2. You can buy a Mac with Lion after its release, and erase and install Lion from the prebundled DVD, but that install will only work on the Mac it shipped with or similar vintaged/model Mac.

     

    This may change, but Apple has not announced any other possibilities.

     

    There is no indication a retail DVD of Lion will be available.  But that doesn't mean it couldn't become available if enough people asked for it here:
