Schmitz Apple has released [1]iMac Graphics Update 1.0 to address an issue for specific iMac models released since September, 2013. In particular, this update resolves a bug that could cause the system to stop responding, display a black screen, or restart when opening very large JPEG images. The Apple support page notes that this update is for 21.5- and 27-inch models released in late 2013, plus the 27-inch iMac with Retina 5K display released in late 2014. The list does not include the entry-level iMac introduced last year (see '[2]Apple Introduces Entry-Level iMac for $1,099,' 18 June 2014). This graphics update is available via Software Update or via direct download from Apple's Support Downloads Web site.
