Apple has released the iMac Wi-Fi Update 1.0, which is recommended for all iMacs released since late 2009 that are running Mac OS X 10.7.3. The update resolves an issue that can prevent an iMac from automatically connecting to a known Wi-Fi network after waking from sleep. It’s available for direct download, but it’s easier to get through Software Update, where it will appear only if it’s necessary for your iMac. (Free, 25.81 MB)
