Apple this weekend apologized to its customers for ongoing shipping delays of its recently introduced 27-inch iMac computer.
"The new iMac has been a huge hit and we are working hard to fulfill orders as quickly as possible," an Apple spokesperson told ZDNet sibling site CNET. "We apologize for any inconvenience or delay this may cause our customers."
Apple did not comment on what was causing the delay, CNET reports. Display problems on the new systems have been widely reported in the last week -- flickering, tearing and outright black screens, according to this lengthy support thread.
Gizmodo reported on Oct. 4 that the systems' ATi graphics card was the source of the problem:
Apple's new iMac has been plagued by random—but reproducible for some—freezing issues, and it appears that the ATI Radeon HD graphics card and its drivers could be to blame.
Engadget reported on Nov. 24 that its own reviewers received a problematic Core i7 system that was "dead on arrival," it said:
We're a little more familiar with the DOA issue, since the new i7 we just bought doesn't boot at all, but the cracked screen issue seems to be equally common and mostly affecting the bottom left corner, from what we can tell.
Web designer Scott Pronych has published a Web site with a Flash testing application that allows users to independently test displays for problems.
Apple's online store currently lists shipping times of two weeks for both 27-inch iMac models, while the 21-inch models both report 24-hour turnaround times. Online retailer MacMall reports similar availability.
Apple did not say when iMac shipments would return to normal.
