Apple has released an incremental update to its Mac OS X operating system for personal computers, bumping the software from 10.5.6 to 10.5.7. See, I wasn't kidding when I called it "incremental."

Macworld, however, takes this stuff more seriously and decided to dig a little deeper into the update.

Released at the same time were security updates for Mac OS X 10.4 and for Apple's Safari 3 Web browser.

Updates can be downloaded automatically through the "software update" feature in OS X, or manually from Apple.

A major update to OS X is expected this summer. It's called "Snow Leopard" and will move the system to version 10.6.
