Apple Software Install
Custom Installation
Use this option to add or remove individual Apple software components.
See "
Miscellaneous Manuals". Select the Troubleshooting Handbook - Reinstalling Your Computer's Software.
Clean Installation
A clean installation disables the existing System Folder, leaving all files in place, and directs the installer to create a new System Folder. The old System Folder will be renamed "Previous System Folder," and from there you can drag any fonts, preferences, or other necessary files to the new System Folder. It is recommended that you drag as few items as possible because some items in the previous System Folder may be the source of the difficulty.
See the following documents for additional information:
Install
An installation with no options selected checks the current system files and replaces only the system files that are an older version than those on the disk image.
Apple Software Restore
There are two versions of Apple Software Restore. The first version is for computers that came only with Mac OS 9.1 and earlier. The second version is for computer that came with both Mac OS 9.1 and Mac OS X. If your computer came with both Mac OS 9.1 and Mac OS X installed on the hard disk, you should follow the restore procedure outlined in "
Apple Software Restore: How to Perform a Multiple Disc Restoration" because the features listed here are not included with the multiple disc restoration.
Restore in Place
A restore in place replaces all the software that came installed on the computer without version checking. Extensions conflicts caused by third-party software may persist, because third-party software is unaffected by this type of install. See "
Apple Software Restore: Some Preferences May Be Lost"
Important: Performing this action removes most updated system software components installed after the initial use of the system and replace them with what was originally installed upon first use. It is necessary to reinstall updates after the "Restore in Place" procedure has completed. It is not necessary, however, to reinstall firmware updates after this action is performed. On computers running Mac OS 9 or later, using the Software Update feature should ease any confusion about which updates are necessary and should automate the process of installing the updates. For more information about using the Software Update feature, see "
Mac OS 9: How To Use The Software Update Control Panel".
Erase and Restore
An erase and restore erases the entire contents of the hard disk and restore it with the original disk image. See "
iMac: System Software Reinstall Options".
Restore
