It hasn’t happened to me, but a lot of users of the new metal iMacs have been experiencing inexplicable freezing incidents where the only solution is to hard-boot the computer, and recently Apple has acknowledged the problem, according to Macworld.
An Apple spokesperson told them “A small number of iMac users have made us aware that a recent software update issued by Apple can sometimes cause their iMacs to freeze, requiring them to restart their iMac.”
Apple apologized to users and promises to track down and fix the problem, hopefully in a few weeks. “We are tracking down the root cause of this bug, and will issue a software update which corrects it as soon as we can — most likely later this month,” the spokesperson said.
