TOPIC
There is some confusion between the different types of installation options available with "Apple Software Install" and the different types of installation options available with the "Apple Software Restore" operation. This article explains the different types and references the Knowledge Base articles that explain them in more detail. (Depending on the model and the version of the Apple software you are using, you may not have all the options listed below).
DISCUSSION Apple Software Install: Custom Installation: Use this option to add or remove individual Apple software components. See article 43033: " 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 Knowledge Base articles for additional information: article 30691: " Mac OS: When and Why to Perform a Clean Install " article 43034: " Troubleshooting Handbook: Performing a Clean Installation " article 58176: " Mac OS 8.5/8.6: Performing a Clean Install " 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: 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 article 31063: " Apple Software Restore: Some Preferences May Be Lost " Important Note: 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 the following article: Article 60504: " 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 article 58023: " iMac: System Software Reinstall Options " Restore: A restore with no options selected places the contents of the Macintosh HD into a folder named Original Items. The hard disk is restored with the disk image. See article 58023: " iMac: System Software Reinstall Options " |
