This may be wishful thinking, but whenever Apple updates its Mac lines this year (I’m expecting August and September announcements), the Mac Pro might finally be among the revamped systems. A clue in an El Capitan info-list file MAY hint at just that, reports PortableOne.
The reference is labeled “AAPLJ95,1”. The entry is part of a compatibility list for Macs. The 2013 Mac Pro’s codename is AAPLJ90,1, which means that “AAPLJ95,1” could be specific to a Mac Pro that may still be in the works.
Apple’s professional desktop hasn’t been updated since late 2013. That’s approximately a century in tech years. The late 2013 Mac Pro uses Intel's Xeon E5 v2 processor family (Ivy Bridge-EP). When it launched, these were Intel's most powerful workstation processors. But they’re starting to look a bit long-in-the-tooth.
