miniclone is a project to create a bootable, useful system on 16 GB of external storage that can open up Microsoft Office documents, open VMware virtual machines, and fix most disk issues.
  • Mac OS X's installation media includes a number of very useful tools for resetting passwords, diagnosing hardware issues, cloning drives, copying data, checking and repairing filesystems, managing disks, and even conducting forensics if you're so inclined. However, there are a number more...

The following notes are based on running the *nix 'diff' command on ver. 1.2 vs. ver. 1.3:

ver. 1.3 allows syncing instead of overwriting if the executable is named something other than miniclone.csh (the comments say 'clonesync' is the alternate name, but the code only checks whether the script's own name is 'miniclone.csh' to decide on sync vs. overwrite)***.

The other changes are to fix a bug where the option to name the target volume something other than /Volumes/miniclone wasn't correctly handled in ver. 1.2 (and earlier?).

*** *nix has "hard-links", which allow a file to have multiple names (this is different from OS X aliases AND from symlinks). Thus an executable can check its own name and behave differently depending on the name by which it was invoked.

Disclaimer: I am not affiliated with the developer of this script nor the developer of any similar application or tool.

I commend the developer for sharing the results of the efforts put into his own personal work - and for free. In a time where we see others publishing almost identical right down to the user interface knock offs of previously published freeware (not necessarily open-source) and then having the gall to charge even just $20/pop, this kind of generosity is notable and unique.

This script or some customized derivative of it - which the dev explains how to do on his website - will be very useful to more advanced users of OS X. The name is a little bit of a misnomer - 16gb is awfully big when the base system of Leopard is an install of ~8gb and SL 6gb - but the dev

If you're new to OS X or any flavor of UNIX, especially if you are a Windows convert and are intrigued by the mention of being able to open MS Office files as being one of the goals of the dev's work here, use this script with absolute caution - not because of anything having to do with the script or the developer, but because of the potentially destructive consequences of some of the actions it performs - especially because once you hit return, invoking the script, that's it, there is no friendly Mac escape hatch at that last minute asking "Are you sure?" and giving you a chance to cancel the operation.

If you've never used the command line or the Terminal utility, if this is your first attempt at trying to clone a drive for a bootable copy, and/or you have no idea what "sudo" is, like you've heard probably time & time again, BACK UP everything important to you before beginning.

If you've never used sudo, there is a good write up here


about it (disclaimer: I am not, nor am I affiliated with, the author of the material at the preceding link). If you find yourself reading it and becoming totally lost or not having a clue what the author is talking about, either do a little more homework before you use the command (some search engine: "os x" "sudo" "command line" should provide plenty of info) or prepare (just prepare - I'm not saying "expect" because who knows what the probability of anything "bad" happening is, varies from one user to the next) for the worst - which just means BACK UP! And if not your entire system, be sure to have your system install discs on hand.

Version 1.2

argh - sorry, I meant to add but somehow got caught off - regarding the install sizes of Leopard and SL and the 16gb size of the resulting "miniclone," the dev explains the size could be smaller and explains how to trim away unnecessary elements to do just that with his script.

The reason his miniclone is 16gb is because that was his preference, it includes all of the things he needs, at a minimum, on a bootable clone.
