According to Apple retail contacts, Apple’s thinner, redesigned 21.5-inch iMacs have begun arriving in small quantities to select U.S.-based Apple Stores, not to all stores, ahead of the Friday, November 30th launch. It is possible that stores that have yet to receive shipments will see their deliveries during the day tomorrow.

The new 21.5-inch iMac will be available to order through Apple’s online store tomorrow as well per Apple’s announcement earlier this week.

Apple CEO Tim Cook previously said there would be iMac shortages into the new year:

On the iMac we’ll be constrained for the full quarter in a significant way… there will be a short amount of time to manufacturer and ramp those and i expect demand to be robust… we will have a significant shortage

Additionally, readers in Australia share that they have managed to purchase the computers at Australian stores this morning (seen in the image above). However, the new iMac is not on sale through the Australian online Apple Store yet.

The new 27-inch iMac will go on sale in December.

The new models include an all-new design with a complex manufacturing process, improved screen design, and a much thinner and light form-factor. The computer lacks an optical drive to make this happen.
