Hello there Vupakot,
It sounds like you are trying to install Mac OS X 10.6 but are getting this error message that some files cold not copy. I want to recommend these troubleshooting steps from the article named:
Troubleshooting Mac OS X installation and software updates (Mac OS X v10.6 and earlier)
Restart and try again
Restart your Mac, then try the installation again.
Use Disk Utility
If the issue persists, use Disk Utility to check your Mac OS X volume. You can verify a disk while started from it. If repairs are needed, start from your Mac OS X install disc and use Disk Utility to repair.
If installation stops during "optimization"
If the installation stops during "optimization," all of the software was installed. There is no risk of an "incomplete installation." The optimization phase of an installation only affects performance and not stability or features. You may force optimization to be repeated by reinstalling the software. If you were using the Software Update pane of System Preferences on the first attempt, you will need to download the standalone installer of the same software from Apple Downloads in order to reinstall the software.
If you cannot install from a disc
- Make sure you are using a compatible disc. See About restoring the correct version of Mac OS X.
- If you have trouble using an installation disc, see Troubleshooting Mac OS X installation.
Try a different software update source or disc if possibleSoftware Updates for Mac OS X and Apple applications for Mac OS X are often available in different ways:
- Software Update preferences
- Standalone installer from Apple Downloads.
Try getting the software from a different source, or download it again.
Try a new administrator account
Creating a new administrator account and using it to install the update may lead to success. If you don't know how to do this, see the "If the issue occurs in Mac OS X or in various applications" section of this document: Mac OS X: How to troubleshoot a software issue.
If this works, log out and back in as your normal user. You may delete the new administrator user, if desired.
Disconnect devices not used during installation
If the issue persists, disconnect any other drives you may have connected to your computer and retry your installation. Other devices could potentially affect your installation. Disconnect or remove anything that did not come with your computer.
Remove non-Apple RAM
For installations from a disc, marginal-quality memory can contribute to installation issues; issues that may not otherwise be apparent in day-to-day computer tasks. If you have added third-party RAM, remove some of the RAM from your computer, but not so much that you are below the minimum required to install the software.
Erase install as a last resort
Erase installs may succeed where other installations do not. You should make sure you have a working backup of your important data before erasing the volume. Due to the extreme nature of this solution, you may wish to try all other steps first.
Important: Erasing a volume deletes all data on the targeted volume. Back up any data you wish to keep before performing this step.
Thank you for using Apple Support Communities.
