Craig Federighi showed us all the news about macOS Monterey during the WWDC21 keynote last Monday, and at that point we learned about its compatibility as well. However, not all of the new macOS Monterey features will be present on supported Macs: some of them will be exclusive to Macs with Apple Silicon chip
These functions are portrait mode in FaceTime calls, text detection in photos, the globe in the Maps application with detailed maps of the cities, reading spoken text in other languages and offline dictation.
A more limited macOS Monterey, but present
These aren’t essential features, but all Intel-chip Macs will miss them. The rest of the advertised functions will work, but also with some limitations. For example: the spatial sound and AirPlay on Mac will only work with computers from 2018 or later, and Universal Control will do this on select Macs starting in 2016.
Therefore, if you have a Mac with an Intel chip compatible with macOS Monterey, take a look at the fine print on its official website to see what functions you will be able to use because you won’t be able to do them all. Apple did a good thing by bringing macOS Monterey to computers until 2014, but at the same time it wanted the farewell of Intel chips begins to be felt.
