Should you have an iMac of recent vintage that suffers from booting problems, help is on the way in the form of a firmware update from Apple.
iMac Hard Drive Firmware Update 1.0, released Monday, promises to tackle a hard drive issue that prevented some iMacs from properly booting.
The affected models include 21.5- and 27-inch iMacs released in mid-2010.
The 767KB update requires Mac OS X 10.6.7. It's available from Apple's Support Downloads page as well as through Software Update.
