Technical information

Installing a customized system: The Install Mac OS program installs the software recommended for
your model of computer. You can use the Customize option to be more specific about which software
to install. For instructions, see “Performing a Custom Installation,” later in this chapter.
12 Click Start to install the software you selected.
The Install Mac OS program checks your destination disk for any problems and repairs them, if
necessary.
After your disk is tested, the software you selected is installed.
13 When the installation is complete, restart your computer.
If your computer does not start up properly, see “If the Installation Was Not Successful,” next.
14 If necessary, install or reinstall other software that may be missing from your startup disk.
If you erased your hard disk prior to installing system software, certain system extensions or
application programs that were originally on your hard disk may need to be reinstalled. Some
additional extensions and programs are on the CD-ROM disc that contains system software. System
extensions or application programs from other vendors can be reinstalled from their installation disks.
If the installation was not successful
If a message reports that installation was not successful, try installing again. (Follow the instructions on
the screen.)
If, after reinstalling system software by doing a normal installation, you still experience problems with
your computer, follow the steps in the section for performing a “clean” installation of system software,
later in this chapter.
