Apple has released a graphics update for a number of models of their iMac desktops.

The update fixes issues that may cause an iMac to become unresponsive when looking at large JPEG images in Finder or Preview. The problem impacts three iMac models, including the iMac with 5K Retina display.

  • iMac (Retina 5K, 27-inch, Late 2014)
  • iMac (21.5-inch, Late 2013)
  • iMac (27-inch, Late 2013)

The fix is available for download at the link below. Apple has more information about this fix in their support article here.
