![]() ![]() Similarly, if you didn’t install Rosetta or QuickTime 7, and you later try to open a program or media file that requires that software, OS X will offer to download and install it on the fly (assuming you have an Internet connection, of course). For example, if you didn’t chose the All Available Printers option and you later try to use a printer that’s not supported by your original installation of drivers, OS X will connect to the Internet and download drivers as needed. If your Mac has an active license for QuickTime Pro 7, this option will be enabled by default.Įven though you have all these options to consider, don’t spend too much time worrying about what to install: unlike Leopard and earlier OS versions, Snow Leopard can automatically download and install some software on demand. Check this option to install QuickTime 7 for backward compatibility. This Apple support document for details). However, the new version may not support some older media formats that QuickTime 7 handled with aplomb (see If there’s a chance you have older Mac software that never made the jump to Intel code, you should install Rosetta-although, as with printer drivers, Snow Leopard is forgiving here (see below).Ī new version of QuickTime that claims to offer many improvements over QuickTime 7. Rosetta Disabled by default, Rosetta is the behind-the-scenes program that lets you run many PowerPC applications on Intel Macs. On the other hand, at approximately 64MB, it’s worth installing just in case you ever come across an app that needs it. If you use X11, chances are you’ll know it.

You can also opt out of specific language translations click the disclosure triangle to reveal the individual languages, and then check only the languages you think you’ll actually use. Though enabled by default, you can disable it to save a few hundred megabytes. Language Translations This option installs support files that let you use Mac OS X-in other words, view menus, dialog boxes, and other OS-related text-in other languages. In fact, by doing so, you gain a number of specialty fonts that could be useful even if you don’t speak any of these languages. While you can’t choose a subset of these fonts, the whole package is small enough-somewhere between 40MB and 120MB, depending on which fonts you already have on your drive-that there’s little downside to installing them all. For more on why you might want to choose this route, see “Why Erase and Install?” below.)Īdditional Fonts This option installs fonts for Chinese, Korean, Arabic, Hebrew, Thai, Cyrillic, Devanagari, Gujarati, Punjabi, Tibetan, Armenian, Cherokee, and Inuktitut.

(The exception to the steps just mentioned is if you want to check, repair, or erase your hard drive, or use other utilities, while booted from the Install DVD. Instead, you get to choose your install options immediately: just click Continue, accept the license agreement, and you’re taken to the options screen. When you insert the Snow Leopard DVD in your Mac and double-click the Install Mac OS X icon, you aren’t immediately prompted to restart as you have been with previous installers. (Don’t forget to check for new versions of preference panes and other add-ons that run in the background.) Finally, as with any major software update or upgrade, you should be sure to back up before installing Snow Leopard. Let me also suggest that a major OS upgrade is the perfect chance toĬheck your drives for problems, clean house, and check for updates for your frequently used software. Similarly, if you’ve installed an aftermarket video card in your Mac, be sure to check with the card’s vendor to see if there are new Snow Leopard-compatible drivers you need to download and install. Before you begin installing, it’s also worth checking to see if your Mac requires any firmware updates Apple offers a While these are the official requirements, I recommend 2GB RAM and at least 10GB of free hard-drive space for a much better experience (both during installation and afterward). ![]() 5GB free hard-drive space (7GB if you plan to install the Snow Leopard developer tools).A built-in display or a display connected to your Mac’s stock video card. ![]()
