As Apple continues its transition to custom chips in various products, such as the Mac lineup, it is only natural that previous-generation hardware will have to be discontinued, and on this occasion, the company had to pull the plug on its Intel-based 21.5-inch iMac.

Apple did not publicly state that it had discontinued the 21.5-inch Intel iMac, but at this point, it did not really matter because we suspect no one was really interested in getting that, especially when you have far better options to choose from, such as the redesigned M1 iMac. The discontinued hardware included a 2.3GHz dual-core 7th-generation Intel Core i5 processor, along with 8GB of RAM, a 256GB SSD, and Intel Iris Plus Graphics 640 for $1,099.
