The iMac is a flagship of the brand, but instead, it has not received any update during 2018. Therefore, you will most likely see a renewal in the coming months. Apple has to risk something in its designs, to continue to convince many users who do not see progress in the latest Mac, but do detect an increase in price.
Therefore, after the last update of June 2017, you will most likely see new iMac models in this 2019. But in the forums we found two opinions: internal and external change or only hardware improvements.
Many consider the iMac model to be already amazing and continues to be current, after many years with us. Only some manufacturers have dared to make a design similar to the iMac in terms of innovation in their designs, but the vast majority have not entered into the design of a monitor that contains the hardware of a computer inside.
On the other hand, other users think that the new iMac should follow in the footsteps of its older brother and innovate in design, as the iMac Pro did with the Space Gray color. Among these supporters, they explain that Apple must build an iMac that is the dream of any makeup artist, more if possible, when more and more, users opt for portable models for the versatility and the power that a eGPU.
Among the wish list we find a iMac with screen without any frameworks (this dream is repeated in every Mac that comes out on the market) a keyboard with Touch ID and Touch Bar like MacBook Pros and up to an extension of AirPower that allows us to charge our devices while we are working with our Mac. In this way Apple would again attract many unhappy users and give a second chance to customers who opt for a laptop, connected to an external screen when they use it as a desktop.
