Apple Discontinues 512GB and 1TB SSD Configurations of 4K 21.5-inch iMac

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.

An all-new redesigned iMac based on Apple silicon is expected to launch later this year, but a more specific launch timeframe isn't yet known.

Chip shortage. Can’t see it getting better anytime soon either.
There’re not out of stock though. They’re discontinued, meaning Apple no longer intends to sell them.

If the M1 iMac is 2nd half of this year. This makes no sense. 512GB is a great option so they must be predicting long-term chip shortages. The M1 MacBook Air is very hard to find in stock right now, so Apple is obviously struggling like others for parts. Dell is quoting 90 days on custom laptop builds right now for my office.
