The firmware updates, they keep on rolling in.
Late Friday, Apple released iMac Wi-Fi Update 1.0, a 25.8 megabyte download that resolves an issue that may cause an iMac to not automatically connect to a known Wi-Fi network after waking from sleep. It is recommended for all iMac (Late 2009 or newer) users running 10.7.3.
The firmware update is available either via direct download or through Mac OS X’s Software Update feature on a qualifying iMac.
If you’ve tried the iMac Wi-Fi Update 1.0 upgrade and have any feedback to offer, please let us know in the comments.
