For New Upgrade To AIn some cases, you may also want to use the Restore Software CDs/DVD that came with your computer. Mac OS X is installed on your drive, but you want to upgrade to a major new version (such as when going from Mac OS X 10.3 Panther to Mac OS X 10.4 Tiger), or you want to reinstall a version already installed (perhaps in hopes of eliminating suspected problems with the currently installed copy).The primary way to install or reinstall Mac OS X is via the Mac OS X Install CDs (or DVD)—which either came with your computer or you purchased separately. You erased a drive on which Mac OS X was installed (perhaps because it contained corrupted data you could not fix), and you now want to reinstall Mac OS X. Presumably, you purchased a retail version of Mac OS X, and you now want to install it. Mac OS X has never been installed on your Mac.For Mac OS X 10.4 Tiger, the retail version is sold only as a DVD. The Mac OS X Install disc(s)The Mac OS X Install software is provided on either CD or DVD. I discuss all of these variations in the sections that follow.Disc 3 contains the X11 software, Additional Speech Voices, more printer drivers, and a few other components. Pkg files in its Packages folder—including those that contain the software for iCal, iMovie, Microsoft Internet Explorer, iPhoto, iSync, iTunes, and StuffIt Expander—as well as files for additional printer drivers and for foreign language support. Disc 2 includes numerous additional. The main installation of Mac OS X software takes place from Disc 1. On newer Macs—which come with optical drives that can read DVDs—Apple ships a bootable DVD that contains both a Mac OS X installer and a more comprehensive installer that will restore all the original software (including the OS and third-party applications) that came with your Mac.Older Macs—especially those that didn't include an optical drive that can read DVDs—include similar Install content on three or four CDs: Install Disc 1, Install Disc 2, Install Disc 3, and possibly Install Disc 4. However, that was an extension of a previous deadline of July 9, 2005, so it's possible that Apple may end up further extending the deadline. Do so, and your Mac will restart, booting from the Install disc.Alternatively, you can start up from the DVD by accessing the Startup Disk System Preferences pane, selecting the DVD, and clicking the Restart button. Next, assuming you're running Mac OS X already, you will be prompted to give your administrator password. (Note: On Restore discs, it's in the Welcome to Mac OS X folder that's visible in this window.) In the window that appears, click the Restart button. Next, double-click the Install Mac OS X icon, which should be visible in the window that opens by default when the disc mounts. To do so, insert the DVD and wait for it to mount. If you choose Restart, your Mac will simply restart without any changes being made to your hard drive. Choosing Startup Disk launches the same pane that appears when you choose the Change Startup Disk command from the Utilities menu (below). Your choices are Restart, Startup Disk, and Don't Quit. The Installer menuOnly one command is important in this menu: Quit InstallerIf you select this command before you install Mac OS X, a window will appear, asking if you are sure you want to quit the Installer. The safest bet is to start up from the disc. You should now be able to install the software.Note, however, that you do this at your own risk: I've seen cases where it hasn't worked. Download game ppsspp ultraman fighting evolution 3The included utilities are the following: Startup DiskThis utility, which functions much like the Startup Disk pane of System Preferences, comes in handy if you can't get your Mac to start up from a particular hard drive or get it to shift to an alternative bootable hard drive as its default choice. Choosing an item from this menu launches one of the separate utilities located on the disc to exit any utility and return to the main Install pane, choose the Quit command from the application menu. The Utilities menuThe Utilities menu that appears when using current Mac OS X Install discs combines a number of utilities found in the Installer menu of older discs, as well as a few new items of particular interest to troubleshooters. Although this information is not critical for the initial installation, it will become of more interest when you update the OS and want to see what files the updater installed.Figure 3.5 A Show Files listing in an Installer. You can save this list as a text document. The command is likely to be active by the time the Select a Destination pane appears and certainly no later than after the installation has completed (and before you restart).If you choose this command, you will get a list of every file that gets installed by the current Installer setup and the exact folder locations in which each file will be placed. Click Save to save your changes.This arrangement also represents an obvious security weakness, since it means that anyone with a Mac OS X Install disc can change your password to gain access to your system (although you can set an Open Firmware password to prevent this, as described in Chapter 5). Reset PasswordIf you've already installed Mac OS X, you can use this command to enter a new password for any Mac OS X user on any mounted Mac OS X volume—an important back door of last resort in case you cannot recall your own password. Once you've done this, click Restart to reboot the Mac using that drive. The only times it will be apparent that just one hard drive is at work are when the hard drive fails or if you need to reformat it.All drives ship from Apple with just one partition. In most respects, the volumes behave just as if you had two (assuming you made two partitions) separate hard drives (rather than just one). Each volume in turn mounts separately when you launch your Mac. In addition, you cannot launch the Reset Password utility directly and use it—it can be used only if your computer is booted from the Install disc.Partitioning a hard drive means dividing it into two or more separate volumes.
