Updating Mac OS X offline
Thursday, May 10th, 2007Tired of leeching tons of megabytes on updates after re-installing your system? Here is the solution!

Who does not know this problem. After re-installing your system there are a huge amount of updates to download and install. Even for those having a fast Internet access it takes a while. And what to do if you have to keep more than one system up-2-date.
The German computer magazine c’t came up with a neat solution (Artikel aus c’t 10/07, S. 192). They created a little application based on AppleScript that does the work for you.
It is called OliU (OfflineUpdates). You can download it here. The archive contains three files
- OliU.zip The application OliU, which you have to copy to your hard disk
- ctOliU.src.zip The XCode-project, to customize it
- wget-1.10.2.tar.gz The source code of wget, that was used to create wget, whis is part of OliU.
The application will do the download for you and create a disk image. You can store that then either on DVD-R(W) or on an external drive like your Apple iPod. Or you can put it in your “Web-Sites”-folder and distribute it over the local network.
The OliU works for both Intel- and PowerPC-based Macs. Even the application updates are included. The only restriction is, that Mac OS X earlier than 10.4 are, due to update mechanism, unsopperted.
A little legal information: The application is copyright protected and not Public Domain. It is not meant to be used as commercial.
You are encouraged to copy and distribute the tool or parts of it as long as
- you do not charge money for it and
- keep the user informed about the origin of it.
