Apple is on a roll with its updates. Following Friday’s iPhone 2.1 software update, which seemed to solve many issues customers were having with the device, the company launched an update for the Front Row software last night. Today, Apple has another another big one, the new version of OS X, version 10.5.5.

Looking over the release notes, reliability seems to be a major theme. Notably, Apple’s cloud-based applications and backup services which it calls MobileMe, has two reliability fixes. The service has had numerous problems since its launch earlier this summer.

Apple is creeping closer to OS X 10.6, dubbed “Snow Leopard,” which is expected to launch sometime in the first half of next year, but was shown off a bit to developers at this year’s WWDC.

The rest of the 136 megabyte (for the iMac anyways, it seems much larger for my MacBook Pro) OS X 10.5.5 update includes the following:


Includes recent Apple security updates.
Addresses stability issues with video playback, processor core idling, and remote disc sharing for MacBook Air.
