For months since the iMac with 27-inch screen was released in October, users have been complaining about various issues with the display. Apple maintained silence about the problems for months, until finally acknowledging that some screens had a flickering problems in December and releasing a firmware update to fix it. Now, weeks after issuing a second firmware fix that it claims solves the problem, Apple is finally publicly admitting that there was a problem with screens showing a yellowish tinge.
An Apple spokesperson directly acknowledged the yellowing problem for the first time in a statement to Gizmodo.
"We've addressed the issues that caused display flickering and yellow tint," the spokesperson said. "Customers concerned that their iMac is affected should contact AppleCare."
Shipping turnaround times listed on the Apple website have often surged to as much as three weeks as problem reports continued to mount, causing Apple to go so far as to publicly deny a rumor
that it had stopped production of the iMac in order to find a fix to the problems. Now that Apple claims to have fixed the problem, shipping times for the 27-inch iMac are now displayed on the website
as no more than three to five days. Apple has always maintained that the delays were just because of the high demand for Apple's flagship computer. The new iMac was the best-selling desktop
in the U.S. when it debuted last October, with the 21.5-inch model taking first place and the 27-inch iMac the third-best-selling machine.
Apple released a firmware patch
in December called iMac Graphics Firmware Update 1.0. Then, in February, Apple sent out a second fix
called iMac Display Firmware Update 1.0 which was listed as being specifically for iMacs shipped in late 2009 only. An Apple service outlet in the UK reported at that time that Apple was offering a full refund plus a 15 percent bonus
to some users whose issues had not been resolved after multiple tries.
Gizmodo, which has been very vocl in publicizing the issue and pressing Apple for a response, has cautioned new iMac owners to test their computers
before concluding that the problem has been resolved. Even if a fix is in place, defective iMacs may still be in the pipeline, and Gizmodo notes that users may need to return their computers for working ones.
