Just hours after officially discontinuing the iMac Pro, Apple has also discontinued the 512GB and 1TB SSD configurations of the 4K 21.5-inch iMac. 

Last month, both options became unavailable for purchase, although it was unclear at the time whether it was a temporary issue due to a component supply problem or if it was a permanent decision to no longer offer the options.

Apple has now removed both of the affected SSD options from the ‌iMac‌’s configuration page entirely, leaving a 256GB SSD and a 1TB Fusion Drive as the only options for customers.
