Apple's big-screen 27-inch desktop iMac still has a shipping wait time of three weeks, and one new report has alleged that the company has ceased production of new units until it can address hardware issues.

Citing an anonymous source, Hardmac reported Monday that Apple has allegedly stopped assembling lines for the desktop. Supplies of the 27-inch iMac have been restricted for months as reports of screen flickering have persisted. While some have speculated the lack of availability has been due to those issues, there has been no confirmation from Apple.
