Apple today released the next major update to OS X Leopard in the form of Mac OS X 10.5.6 and is now available via Software Update, or the Apple downloads page. It is a 377MB download, recommended for all users running Mac OS X Leopard.

Some of the notable changes and updates included in the release are:

  • Contacts, calendars, and bookmarks on a Mac automatically sync within a minute of the change being made on the computer, another device, or the web at me.com. This should go a long way towards making MobileMe more usable.
  • Improves reliability of Address Book & Airport.
  • Adds a Trackpad System Preference pane for portable Macs.
  • Improves Time Machine reliability with Time Capsule, and problems with locating backup volumes
  • Includes fixes for possible graphics distortion issues with certain ATI graphics cards, and improvements for several graphics intensive apps (iChat, Cover Flow, Aperture, and iTunes).
  • Several improvements to Mail to improve performance, junk filtering and handling of PDF attachments
  • Networking enhancements for AT&T 3G cards and TCP connections
  • Improved printing for users of Adobe CS3

As ever with updating to the latest software version, Apple recommends that you:

  • Back up your computer prior to installing any updates.
  • Quit any open applications before starting the installation.
  • Do not interrupt the installation process.

They also note that you should take care with any third-party system software modifications installed, or if you have moved Apple applications from their default locations (the /Applications or /Applications/Utilities folders).

For full details and download instructions, see the official release page.

Do let us know how the update process goes!

  1. It was only 190mb download on my iMac G5 2.1 ghz. Went smoothly and installed nicely. I am always impressed with Apples download speeds when publishing these large files. Very fast.

    I’ve had no problems on my Black MacBook or my aluminum iMac. It may have improved some occasional glitchy issues with my ATI Radeon card on the iMac, in fact.

    Having troubles maintaining wireless connectivity with 10.5.5 and my Trendnet Wireless G router recently, so I’m hoping this update will fix my problems. But I’m getting timeouts even trying to download the files in the first place through SoftwaeUpdate! Anyone else having these problems?

  4. We tried to upgrade one machine in the office and it got stuck “Configuring Installation…” until we rebooted. 2 other friends emailed me about their machines doing the same thing.

    I think we’ll wait a few days to do the entire office….

  5. I have the same “Configuring Intallion…” hanging trouble on my first gen 15″ MacBook Pro.

  6. Just updated new MBP 15″…worked like a charm….really like the MM improvements.

  7. Glad to see they finally got MobileMe push working on the Mac!

  8. Using the complete download fixed the hang.

  9. My “config install” ……. freezes up too. maybe I should wait

  10. Since the upgrade I cannot start Mail anymore, it hangs when trying to read a message already stored in a local mailbox. Not sure if it’s related to .6 but…
