Macintosh System 7.5.5 Update Overview

Who should install the System 7.5.5 Update?

Apple recommends that all customers who are currently using System 7.5.3 should install the System 7.5.5 Update. If you are using a system software version prior to System 7.5.3, you must upgrade to System 7.5.3 before you install this update. (If you are using System 7.5, 7.5.1, or 7.5.2, you can use System 7.5 Update 2.0 to upgrade to System 7.5.3.).

What does installing the System 7.5.5 Update do?

After you install the System 7.5.5 Update, you should notice improved performance and stability, specifically:

• Significant performance improvements when using virtual memory. If you use virtual memory, this software improves the time it takes to:
  • launch a large application program that requires a significant amount of RAM
  • switch between large application programs
  • switch between large documents within an application
  • access SCSI devices

• Improved memory management on PowerPC computers If you could not launch an application program because you did not have enough RAM to open it, you may be able to use the application after you install this update. This update also eliminates the cause of one Type 11 error.

• Improved reliability when using floppy disks in a computer equipped with a DOS Compatibility Card If you have a computer with a DOS compatibility card installed, you may have experienced problems inserting floppy disks while Windows is launching. This software fixes this problem.

• Improved reliability on PowerPC PowerBook computers (PowerBook 5300 and 2300 series computers) and PCI-based computers (Macintosh 5400, 6400, 7200, 7500, 7600, 8500, and 9500 series computers) If you have a PowerPC PowerBook or a PCI-based computer, your computer may have "frozen" from time to time while accessing a hard disk. This update fixes one cause of this problem.

• Improved reliability when using Ethernet and virtual memory If you use Ethernet and have virtual memory turned on, you may have experienced problems transferring large files over Ethernet. This update fixes this problem.

• Better reliability when using the Apple TV Tuner or Macintosh TV Remote Control When using the remote control for the Apple Video Player, the channel and volume buttons may have stopped working when you press them rapidly. This software fixes this problem.

• Improvements in LocalTalk This update includes improvements in LocalTalk that provide:
  • better reliability on Macintosh 5400 series computers
  • better performance when using some third-party infrared software products

• Improved stability when using multiple background application programs If your computer crashed when using more than one background program, this update fixes the problem. A background program is one that works behind the scenes, so you don't see it in the Application menu. Some e-mail programs have this background feature.

• Improved stability when using a shared printer on a network If your computer crashed when you were trying to use a shared printer on a network, this update fixes the problem.

• Improved reliability on high performance (180MHz or greater) Macintosh and Mac OS-compatible computers that have the PowerPC 604 or 604e processors If you have experienced system freezes during startup or difficulties when formatting floppy disks, this update fixes these problems.

• Improved reliability when using Ethernet on the Macintosh 5400 and 6400 series computers

• Improved reliability when using sound intensive applications on Macintosh Quadra and Centris computers that contain the PowerPC upgrade card

• The "System 7.5.5" extension set in Extensions Manager now includes all of the QuickTime 2.5 extensions.

  With this update, you also get the following enhancements, which were available with System 7.5.3 Revision 2:

• Better reliability for PowerBooks using RAM Doubler If you have a PowerBook using system software 7.5.3 and you use RAM Doubler (version 1.6.1 or earlier), you may have experienced a problem when waking your PowerBook from sleep. This software fixes this problem.

• Overall performance enhancements for PowerBook 2300 series and PowerBook 500 series computers with the PowerPC Upgrade Card installed

• Improved reliability when using PC-formatted floppy disks with PowerBook 500 series computers with the PowerPC Upgrade Card installed If you have a PowerBook 500 series computer with the PowerPC Upgrade Card installed, PC-formatted floppy disks that were formatted on your computer may be unreadable in DOS or Windows computers. This software fixes this problem.

• Improved reliability on PCI-based computers and PowerBook 5300 computers, PowerBook 2300 computers, and PowerBook 500 series computers with the PowerPC Upgrade Card installed

• Improved reliability when copying files to some 1 gigabyte hard disks If you have a PCI-based computer with a 1 gigabyte hard disk, this software helps avoid problems when copying files to the hard disk.

• Improved reliability when using the Startup Disk control panel In rare instances, when you turn on a PCI-based Power Macintosh computer it may not start up from the disk selected in the Startup Disk control panel. This software fixes this problem.

Important information regarding System 7.5.4 Update:

System 7.5.4 Update was released by Apple Computer to a limited distribution, prior to an anticipated general release. Shortly after this limited distribution, an issue with the software was found which required a revision. This revision was named System 7.5.5 Update. It replaces System 7.5.4 Update and will install on computers which have System 7.5.4 Update installed.
