How to do it:
- Use Disk Utility to make a read/write DMG of a 10.6.7 install disk for a MacBook Pro or iMac. Version 10.6.6 might work, but I haven't tried it.
- Set the Finder to reveal hidden files:
- open Terminal and type or copy and paste the following line:
defaults write com.apple.finder AppleShowAllFiles TRUE
- Press the Enter key.
- Then type:
- Press the Enter key again.
- To reverse this, rerun with FALSE instead of TRUE and killall Finder again
- Insert a 10.6.0 or 10.6.3 OSX retail installation disk in your DVD drive and use the Finder to open the disk to system/Installation/Packages/
- One of these package files is OSInstall.mpkg which is the set of instructions for the Installer. This file in the 10.6.7 Installer is where the checking is done to see if it's installing to the 'correct' computer.
- Open another Finder window, and navigate to the same place in the 10.6.7 Installer. Replace the existing OSInstall.mpkg file with the one from the retail disk plus copy over all the printer related Installer packages. We do this because the retail installation script won't install the 10.6.7 printer packages. Check the 'copy all' box when the Finder warns you that the files already exist.
- Open Disk Utility and plug in an 8 gig thumb drive. Find the drive on the left side of the Disk Utility window and click on it. Now click Partition, chose 1 Partition, give it a name and click the Options button. Choose the GUID partition choice and close the window. Click the Partition button. When the Disk Utility is done, use SuperDuper or Carbon Copy Cloner to clone the modified 10.6.7 Installer to the 8 gig keychain drive. I had problems getting the Backup utility in Disk Utility to do this. You can boot any ready for Snow Leopard Mac with this Installer.
[crarko adds: I know we've published hints like this in the past, but I just want to point out that the intent here is not to rip off Apple, but to handle what can be a very messy systems management issue in environments with many different models of Macs, using the tools that are available.]
