This section provides current information about Mac OS 9.1. Starting up from the Mac OS 9.1 CD If you start up from the Mac OS 9.1 CD, some features (such as the ability to play QuickTime movies in Mac OS Help) are not available. Use of all features is restored when you restart from your hard disk. Using Acrobat PDF documents Some documents included with Mac OS 9.1 were created using Adobe Acrobat (these files have "pdf" at the end of their names). To view or print these documents, you must install Adobe Acrobat Reader, located in the Adobe software folder on the Mac OS 9.1 CD. Drive Setup and Energy Saver If you need to use Drive Setup to perform an operation that takes more than a few minutes, such as testing a disk or initializing a disk with a low-level format, make sure your system will not go to sleep by dragging the slider in the Energy Saver control panel to "Never." You can return it to your previous setting after the formatting is complete. PowerBook (FireWire) If you have a PowerBook with built-in FireWire ports, install the PowerBook Firmware update 2.7 to ensure that the FireWire ports work correctly. For more information, see the following Web site www.apple.com/firewire Monitor resolution changes after installation After you do a clean installation of Mac OS 9.1, your monitor resolution may change from its previous settings. You can change your monitor resolution back using the Monitors control panel. America Online (AOL) and QuickTime To view QuickTime content while using America Online (AOL), drag a copy of the file "QuickTime plugin" into the AOL Plug-ins folder (located in the same folder as the AOL application), then reopen AOL. Notes about compatibility Mac OS 9.1 and Mac OS X Public Beta Mac OS X Public Beta and Mac OS 9.1 are not compatible. If you install Mac OS 9.1, the Classic environment in Mac OS X Public Beta will no longer function. Apple CD-ROM extension and non-Apple CD/DVD driver incompatibilities If your CD/DVD drive is not manufactured by Apple, or you have an Apple CD/DVD drive and you use a non-Apple driver, your CD/DVD drive may not function correctly. Remove the file named "Apple CD/DVD Driver" from the Extensions folder (in the System Folder), and reinstall the software that came with your CD/DVD drive. Contact the CD/DVD manufacturer to see if you have the latest version of their software. Applications that install QuickTime Some applications replace the version of QuickTime installed by Mac OS 9.1 with an earlier version. If this occurs, you need to re-install QuickTime by selecting "Add/Replace" in the Mac OS Installer, and then doing a customized installation. For more help, open Mac Help and search for "adding or removing system software." Problems opening applications A small number of applications will not open if the system font is not set to Chicago. Others may require additional memory. If you have problems opening an application after you've installed Mac OS 9.1, try these possible solutions:
2. Select the application's icon, then choose Get Info from the File menu. Increase the application's minimum memory allocation by 300K. For more information, see the Memory topic in Mac Help. Language kits Apple's language kits are now included with the Mac OS. If you use language kits, you must upgrade both your system software and your language kits at the same time using the Mac OS 9.1 CD. Previous versions of Apple's language kits are not compatible with Mac OS 9.1. To upgrade your system software and language kits, start up from the Mac OS 9.1 CD by inserting the CD and holding down the C key as you restart the computer. Continue holding down the C key until you see the CD background. Open the Mac OS Installer and choose Customize in the Install Software panel. Select both the Mac OS Install and Language Kits, and remember to select the specific language kits you want to upgrade. Apple HD SC Setup program If you need to initialize your hard disk after installing Mac OS 9.1, use the Drive Setup program on your Mac OS 9.1 CD. Do not use the Apple HD SC Setup program. FireWire hard disk drives FireWire 2.7 includes a new built-in driver for many FireWire hard disk drives. This driver will be used automatically if the disk vendor's driver extension cannot be found. You should still install the vendor's software to get maximum features from FireWire storage devices. Adobe Type Manager and Adobe Type Reunion Changes in Mac OS 9.1 cause an incompatibility with Adobe Type Manager (ATM), ATM Deluxe, and Adobe Type Reunion Deluxe (ATR). The Mac OS 9.1 installer automatically moves the ATM control panel into the Control Panels (Disabled) folder during installation. The latest updates can be found at http://www.adobe.com Notes about printing Switching between a LocalTalk network and a serial printer If you use the same port to alternately connect to a LocalTalk network and a serial printer, the port may not reset properly after you turn off AppleTalk to use the printer. If you have trouble printing after turning off AppleTalk, restart your computer. Reinstalling printer drivers If an icon for your printer is not available in the Chooser after you have done a clean installation of Mac OS 9.1, you may need to reinstall the software that came with your printer. You may also need to reinstall fonts that came with your printer software. Follow the instructions that came with your printer software. Notes about Multiple Users environments Using Epson printers To print on an Epson printer, a user in the Limited or Panels environment should configure the Epson printer driver to use a spool folder located in the user's folder, or another location where the user can create files. In the Epson print dialog box, click the Tools button, then click Configuration. Then change the Temporary Spool and Temporary High Speed Copies folder locations. Printer access in Multiple Users environments Printers that do not appear on the desktop are not shown in the list of available printers in the Multiple Users control panel. To allow Limited or Panels users to use these printers, grant access to "all printers" or allow the users access to the Chooser. PowerBook 5300 and voice passwords If you have a PowerBook 5300 computer, you cannot use voice verification. You must use a typed password. Program compatibility If you are experiencing problems in the Limited or Panels user environments, search Mac Help for "Multiple Users" to find troubleshooting and other important information about configuring your software. Miscellaneous notes Changing filenames updates file modification date If you alter the name of a file or folder in Mac OS 9.1, it will change the modification date of the enclosing folder. RAM disk disappears when resized If you reset the size of a RAM disk on your Mac OS 9.1 system, the icon may disappear from the desktop. Restarting your computer will bring back the icon with the new size. Downloading disk images If you experience problems when downloading and mounting disk images (files with the suffix ".img" or ".smi"), you may need to disable the Mount Disk Images preference in StuffIt Expander. To do this, open StuffIt Expander and choose Preferences from the File menu. Click Disk Images and deselect Mount Disk Images. Power button sleep Slot-loading iMacs, G4 Cubes, and most G4 towers can be put to sleep by pressing the Power button. You can turn off this feature by deselecting the Power button sleep option in the Energy Saver control panel. Apple Remote Access Personal Server If you are using the Apple Remote Access Personal Server and you perform a clean installation of Mac OS 9.1, the server may not answer incoming calls correctly the first time you restart the computer after the installation. Restart your computer a second time before using the Apple Remote Access Personal Server.
