Indeed, this is how things typically work.
#MAX OS X UPGRADE COMBO MAC OS X#
Ideally, assuming that all goes well with the installation, there should be no differences between how a newly installed version of Mac OS X works, whether you upgraded (or, in some cases, even did an Archive and Install) from an older version of Mac OS X or you erased your drive and started over with an entirely new installation. Unexpected Differences Between Updates and New Installs In general, if an installer causes a serious mistake, you will need to reinstall Mac OS X to fix it-and then restore any lost files from your backups. Even worse, when attempting to remove an older version of iTunes, the installer sometimes also removed much of the data on your drive! This horrendous bug was fixed the same day via another iTunes update-but not before hundreds of users lost files.
#MAX OS X UPGRADE COMBO INSTALL#
pkg file contained a nasty quirk: Due to an error in how it was set up to work, the installation sometimes failed to install iTunes at all. Here's one example: When Apple initially released iTunes 2.0 as a free upgrade on the Web, it was supposed to delete any older version of iTunes found on your drive before installing the new version.

Although the risk rises slightly with software that does not come from Apple, even Apple can make a mistake here. And usually your trust is well placed-such mistakes are rare. These script files, typically located in the Resources folder inside the package file, have names like "preflight," "postflight," and "postinstall." If these scripts contain errors that cause permission changes or file deletions that should not occur, you can wind up with serious problems.īasically, you just have to trust that the software developer has not made such an error. pkg that are run as part of the installation can contain instructions to modify permissions of files and folders-or even to delete certain files. In addition, script files within an Install. How can this happen simply as a result of running the Installer utility? The answer is two-pronged: When installing software, you're typically asked to enter your administrative password, which gives the Installer temporary root access. In extreme cases, the system may even become unusable. How and why things can go wrongĪfter installing software, it's possible to start getting permissions errors when trying to launch various applications, including applications unrelated to the one(s) you just installed. And always make backups of critical files before installing an update. Use this time to check the Web (for example, the MacFixIt site) to make sure the software doesn't contain any significant bugs that weren't discovered until after its release.
#MAX OS X UPGRADE COMBO UPDATE#
"Take Note: About This Mac," in Chapter 2, for more on Mac OS X version and build numbers.Īlthough I generally recommend installing updates-Apple provides them to fix bugs and to add new features-I also recommend waiting a few days after an update has been released to do so.

For example, you may see a QuickTime update, an iPhoto update, or a Pages update. Separate updates to specific components of Mac OS X as well as to software not included as part of Mac OS X.These updates, with names like Security Update 2005-05, modify the OS to plug various security leaks, but do not alter the version number of the OS. For this, you need a Mac OS X Install disc.
#MAX OS X UPGRADE COMBO PATCH#
These are the Combo, Delta, and Patch updates, as described previously in "Cautions regarding extracting files from update packages."Note: In no case do these updates contain the complete set of software you need to run Mac OS X.
#MAX OS X UPGRADE COMBO HOW TO#
I gave a brief overview of how to use Software Update in Chapter 2 the following provides some additional details.Īpple releases three categories of updates, almost all of which are available via Software Update: Because Software Update is the simplest and fastest way to stay current, I recommend using it. Apple regularly releases software updates (as opposed to upgrades, as covered in the previous section) and makes them available via both the Software Update System Preferences pane and the Apple Web site.

Once you have installed and (if necessary) initially updated to the latest version of Mac OS X, you will want to keep it up to date.
