Apple has released a pair of new updates meant to fix video-locking issues on iMacs that run Lion and improve hardware compatibility when running Windows in dual boot mode on your Mac. The iMac Graphic FW Update 3.0 is now available for download, weighing in at a paltry 482KB. Apple says the firmware update “fixes a graphics issue that may cause an iMac to hang under certain conditions”. You can also download this update by choosing Software Update from the Apple menu, in which case the update mechanism will determine whether your iMac’s graphics card needs updating and offer the refreshed software appropriately. Also, Boot Camp got a small update for Windows 7 (version 3.3).  The 200MB download includes critical bug fixes and hardware support. It is recommended for all Boot Camp 3.2 users and requires Windows 7 plus an existing installation of Boot Camp 3.2 on your system.
