Get ready for Lion with OS X 10.6.8

SoftwareUpdateApple (s aapl) just released the latest update for Snow Leopard, OS X 10.6.8. Included in the update are countermeasures for the latest variants of the malicious Mac Defender software, improved support for the recently launched Internet Protocol version 6 (IPv6), and enhancements for the Mac App Store made in preparation for the upgrade to Mac OS X Lion.

No word on what specific changes have been made to the Mac App Store, but they’re probably designed to optimize the delivery of OS X Lion, which will be available exclusively through Apple’s official Mac software distribution channel as a 4 GB download. The fact that Apple mentions upgrade preparation specifically in the update notes for 10.6.8, combined with Lion’s announced July arrival time frame, indicates that this will likely be the last minor point update for Snow Leopard prior to 10.7’s release.

Other things the update offers include resolving a Preview problem that was causing unexpected applications quits, and a fix for importing some types of media into Final Cut Pro. Also, frustrated Lisbon-Portugal iCal users should no longer have a problem with timezones. Check out the full list of fixes and changes at Apple’s official support site.

Happy downloading, and as always, let us know if you encounter any problems with the update.
