Apple has halted production of all 27-inch Core i5 and i7 iMac systems, according to an unnamed source cited by Hardmac. Cupertino is working to resolve several display issues and will not resume assembly of the systems until a "reliable and definitive fix" is found.

In December, complaints of a flickering or flashing display prompted Apple to release a firmware update to correct the problem, but user reports of the issue continued to pile in. Additionally, many iMac owners say their display is plagued with a yellow tinge – something Cupertino has recognized internally.

The 27-inch iMac has been nothing but a headache for Apple since it launched last October. Other complaints range from high-pitched whines and whistles to DOA systems – and some were downright smashed. If you intend to buy a 27-inch iMac, it's probably in your best interest to wait until the dust settles.
