Apple has released new firmware updates for their “late 2008” notebooks, which have been plagued with a handful of problems lately, from video issues to problems with third party memory modules. This is the second firmware update issued for the new unibody MacBooks and MacBook Pros, following one issued earlier this year to addresses an issue where trackpad clicks were not recognized.

This time, however, the updates also cover MacBook Air systems. As usual, Apple didn't provide a whole lot of detail about the issues that are corrected by the firmware updates, but apparently they are aimed at improving the sensing and accuracy of the MagSafe Power Adapter indicator light and the battery charge indicator lights, and overall improve the stability of the MacBooks.

The updates should be popping up in Software Update as you read this, though you can also visit Apple’s download section to get the files manually.
