The iMac Pro is nearly here and some interesting information has surfaced on Twitter. A couple of developers have done some digging in the BridgeOS 2.0 software from Apple. According to the information, it appears that the iMac Pro will feature an ARM coprocessor in the form of an A10 Fusion chip. This would be the first time that a Mac has used an A-series chip designed by Apple. The A10 Fusion chip in the iMac Pro could be used for always-on “Hey, Siri,” a feature that’s currently missing from the macOS version of Siri.
