Doesn't the 12 Pro iPhones have 6GB of RAM ?
Isn't that enough if the new M1 Mac that are based on the A14 iPhone chips?
My M1 Mini running with 8GB of UNIFIED MEMORY runs dual displays, dozens of apps at the same time, and does not slow down like the old Intel processors.
Gotta love Apple for integrating their iPad/iPhone chips into their new line of Macs!
