About the Mac OS X 10.3.5 Update (Delta)

This software updates Mac OS X 10.3.4 to version 10.3.5. Tip: If you have version 10.3, 10.3.1, 10.3.2, or 10.3.3, update with the combo update instead.

Important: Read Before Installing
  • You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. This precautionary statement does not apply to the normal installation of application software.
  • The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to install.


There are two ways to update to Mac OS X 10.3.5: Software Update or Standalone Installer. You only need to use one of these methods to update.

Automatic Software Update

Software Update, located in System Preferences, is a tool for automatically downloading and installing the latest Apple software. Software Update may have linked you to this document for additional information about the update.

Note: This update's size may vary from computer-to-computer, when installed via Software Update.

Because some updates are prerequisites for others, you may need to use Software Update more than once to get all available updates.

Standalone Installer (Web Update)

Two different standalone installers (or "Web Updates") are available from Apple Downloads: One that updates Mac OS X 10.3.4 to 10.3.5 (the "delta" update, described in this document), and also a combo update installer which can update versions 10.3, 10.3.1, 10.3.2, 10.3.3, and 10.3.4.

Tip: You don't need one of these if you've already updated via Software Update.

Where do you find these? Go to Apple Downloads.

This type of update, particularly the "combo," is useful if you have multiple computers to update and only want to download 10.3.5 once.


These are some of the enhancements included with the Mac OS X 10.3.5 Update.

Bluetooth enhancements

  • Bluetooth FIle Exchange now works better with Bluetooth-capable Hewlett-Packard printers.
  • Resolves an issue in which an application that's performing an asynchronous Bluetooth operation could quit unexpectedly, if the computer went to sleep before the data transfer was complete and the "Allow Bluetooth devices to wake this computer" preference setting was disabled.
  • Addresses an issue in which Bluetooth File Exchange could unexpectedly quit if you tried to copy several files but one or more of them already existed at the target location.

Networking, Internet enhancements

  • If you had difficulties connecting to the Internet with a Comcast cable modem and your account uses DHCP configuration (as opposed to PPPoE), then this update can help you connect more easily. If it doesn't, contact Comcast for further assistance. (An example of this issue would be that your computer can't get an IP address when connected to the cable modem, and your Network preferences are set to configure via DHCP.) More...
  • Improves the way Safari handles certain kinds of GIFs, including ones that could cause Safari to quit unexpectedly.
  • Reintroduces shorter server pathnames; the overall limit remains 89 characters, but now only 24 characters (instead of 39 with Mac OS X 10.3 through 10.3.4) are reserved for the beginning of the pathname. More...
  • Addresses an issue in which the Finder could unexpectedly quit when connecting to an AFP server.
