Apple has acknowledged receiving complaints about software update 1.1, issued September 13, that has resulted in iMacs freezing up during normal use, and said it would issue a fix as soon as possible. The update was issued to fix bugs, and was recommended for 20- and 24-inch iMac models with 2.0, 2.4, or 2.8-GHz processors. The problem affects a "small number of iMac users. We are tracking down the root cause of this, and will issue a software update to correct it as soon as we can. Most likely later this month. We apologize for the inconvenience," according to an Apple spokesman who declined to give exact numbers.
While Apple reported hearing customer complaints following the update, iMac users reported having problems with the new iMacs in August, the same month they were released. Some people reported the iMac freezing when opening various applications, such as iTunes, FrontRow, and iPhoto.
