A.4. The Upgrade InstallationA.4. The Upgrade InstallationIf Mac OS X version 10.0 through 10.4-point-anything is on your hard drive, the Leopardinstaller can neatly nip and tuck its software code, turning it into version 10.5.Every thingremains just as you had it: your accounts, folders, files, email, network settings,everything-else settings, and so on.This sophisticated surgery occasionally leaves behind a minor gremlin here and there:peculiar cosmetic glitches, a checkbox that doesnt seem to work, and so on. If thatpossibility concerns you, a clean install is a safer way to go. (A clean install does,however, require a little more post-installation fiddling to reinstate your settings, notablyyour Internet and network preferences.)If youre still game to perform the upgrade installation, follow the previously outlinedsteps 1 through 3. On the Select Destination screen, however, click Options.Now youre offered several variations of the basic installation. The one you want isUpgrade Mac OS X. Click it, and then click OK. Proceed with the previous step 4. (Thebutton described there now says Upgrade, though, instead of Install.)
