A few months ago, I did a clean install of mountain lion on my macbook pro (2.66 Ghz Intel Core 2 Duo), and went through all the efforts of installing apps, tools, etc.. Customized my computer exactly how I want it...  Now today, I just got the new 2.9ghz i7 macbook pro, and was bummed when I realized since the new disk space is done via flash chips, I can't just take the SSD out of my old macbook pro and put it in the new one...  So I started the (extemely painful) process of reinstalling everything on the new machine.


Suddenly I thought to myself-- what about Carbon Copy Cloner?  And I wondered, has anyone had experience cloning their actual boot drive and used it as their drive image on the new generation hardware?


Any suggestions / advice?

    Carbon Copy Cloner is the best app to clone disks. If you're using Mountain Lion in the old computer, you won't have problems cloning it into the new Mac.


    To clone the disk, make the clone with Carbon Copy Cloner, connect the external disk to the new MacBook, press Option key in boot, start from the external disk and open Disk Utility to restore the clone

    Your other option could jave been to simply use

    Migration Assistant.  It will copy apps, data. and settings.

    For the most part it works quite well.  There may be a few apps

    that may need a reinstall because of how they may scatter

    stuff across the system (most don't).  Before doing, make sure

    all apps are up to date to work with the version of OSX being

    copied to.

    DO NOT CLONE OS X from a older machine to a newer or different one.


    Clones can only be booted/cloned onto the same model of machine.


    You can run Migration or Setup Assistant against a clone from a older machine no problem as it thinks it's another Mac.


    What Setup/Migration Assistant will do is ignore OS X and copy everything else to the new machine.


    Each machine has special hardware drivers that won't work on other models, also newer machines have newer features that are not included in the older machines operating systems software.


    Actually with new machine I prefer setting up all new copies of programs, for instance your older machine might have 32 bit software, a fresh install of the program can install the 64bit version instead, which can address more RAM.


    The only thing I return to a new machine is cherry picked files from a storage drive into the same named accounts, this way I know what's on the machine is good.



    With SSD's now, they can't be securely erased like hard drives can.


    How do I securely delete data from the machine?

    Not entirely true!  I have a 2009 iMac Clone of Lion on a Firewire

    drive that boots and works quite well on my 2011 Macbook Pro

    and my 2011 Mini server, both of which have Mountain Lion installed

    on them.  I also have a Mountain Lion "emergency" USB stick that

    I have various utililties installed on for troubleshooting.  I created it

    on my 2011 Mini Server and it boots on my Macbook Pro and also

    my 2010 Mini.


    Now, it is true if it is an OS on the clone that is not supported by

    a newer machine, i.e. Snow Leopard on a 2012 Mac.  Also, the 2012

    are a special case as the 10.8.2 that is loaded on them is not the

    same as that downloaded and installed on other machines.  Once

    10.8.3 syncs these differences into the mainstream updates to all

    makes then the issue will be gone.
