The hint of new Mac Pro is seen from the reference on OS X El Capitan according to Pike’s Universum.The identifier model appears in that reference is AAPLJ95,1 and it is similar to the identifier model of Mac Pro 2013 version, AAPLJ90,1. He found this thing accidentally when he was working on XHCI compatibility issues. He found it on AppleUSBXHCIPCI. kext/Contents/Info.plist and here is the XML snippet:
“The data is identical to that of the late 2015 (iMac17,1 in the same file) so it may as well be a remnant of the new iMac, but the strange thing is that the XHCI data for the late 2015 iMac is also there, which is why I believe that this is not/was not added for the/a new iMac but another Mac”, he said.
There is a defined 10 USB 3.0 ports on that reference. It made him think that the 10 port may fit for the new Mac Pro, considered there is no other Apple device fit with the 10 ports, whether that is Mac mini or MacBook Pro. At the moment, MacBook Pro has 10 data ports: 4 USB ports and 6 thunderbolt ports. Will Apple replace all 10 ports to USB 3.0 ports? Or maybe they will adopt the USB type-C completely. Currently, the USB type-C is only used by MacBook 12-inch Retina display. However, this is an interesting thing of what Apple is doing right now.
