Update: Recent reports indicate that the iMac 27-inch will not actually have a mini LED display. The next all-in-one Apple desktop will stick with LCD panels. More details about the new iMac have emerged from reliable sources. This new rumored model will replace the older 27-inch model, and from the sounds of it, it will be more than just a larger version of the 24-inch iMac 2021.

According to display expert Ross Young, a new 27-inch iMac with a flashy new display will appear early in 2022. He initially posted that this would be a discrete display like the Pro Display XDR, but later changed his position and said it would actually be a new iMac coming in the first quarter of next year. However, Apple's new display may appear later, he added.

Like the displays revealed for the new 14-inch MacBook Pro and 16-inch MacBook Pro, this iMac appears to support a maximum refresh rate of 120 Hz, which can be reduced to 24 Hz if necessary. Young also noted that the general LCD display and will feature mini-LED lighting that will provide additional brightness and more accurate colors.

The previous 24-inch iMac, introduced earlier this year, had already introduced a number of major changes, including new design and color options, Apple's M1 chip that powers everything, and a higher quality webcam. The sleeker display will help the larger 27-inch model stand out, but there is also the option to spec Apple's new M1 Pro and M1 Max chips for improved performance without having to buy a ridiculously expensive Mac Pro.

A large, high-end iMac to be released next year has already been rumored. Apparently, Apple did not want to reveal this new iMac for fear of causing internal competition with other newly released Mac devices, possibly the two new MacBook Pros. Since it will be a year since the last iMac was announced, perhaps next April, a new model may be introduced.

The current 27-inch iMac has only been on the market for a little over a year, but it uses an old design that looks dated and runs on an aging Intel processor. A full model change is what Apple needs to complete the switch to the Apple Silicon Mac and continue its lead over similar all-in-one computers, especially if, as Young suggests, it comes with all the goodies.
