Convert OS X Update CD to Install CD
Dominik Gwosdek: Panther Update CD Hack
If you, like me, were frustrated with the $19.95 Jaguar upgrade disc because it would not work as a full installer (it requires that a version of OS X is already installed, will only upgrade – no clean installs), well, worry no more. Now you can get a clean install of Jaguar.
Here is how to make this “upgrade-only�? disc a full installer. The only difference between the “upgrade�? disc and the $129 retail version is that the upgrade disc contains a little file that checks for a previously installed version of OS X. With the following method, you get rid of this check file. All you need is a blank CD-R.
(This only applies to Jaguar disc one. Disc two does NOT check for a previously installed OS.)
1. Insert the Mac OS 10.2 Update CD (disc one)
2. Open Disk Copy (found in the Utilities folder)
3. Select “File – Image – New Image from Device�?
4. Select your CD-ROM drive from the dialog
5. Image as “DVD/CD Master�?
Now modify the contents:
1. Control-click on the resulting disc image
2. Make certain that the disc image is mounted
3. Navigate with the Finder to “System – Installation – Package Contents�?
4. Select the “Essentials.pkg�? file
5. Control-click on the “Essentials.pkg�? file and select “Show Package Contents�?
6. In the pop-up Finder window, navigate to “Contents – Resources�?
7. Here is where we find the culprit! Drag the file titled “Check for OSX�? to the Trash; close all finder windows.
To burn your fully functional Jaguar disc:
1. Return to Disk Copy and select “File – Image – New Image from Device�?
2. Select the mounted volume you opened above and create another “DVD/CD Master�? image
3. Now select “Image – Burn Image�?
4. Select the newly modified .dmg file
5. Burn to CD … that’s it!
