Apple: 2013 Mac Pro - CPU Upgrade & Apple Diagnostics

Created on: September 9, 2016

Q: Will my 2013 Mac Pro pass Apple Diagnostics with a new CPU installed?

A: Due to changes made in newer revisions of the EFI firmware for the 2013 Mac Pro, not all machines will pass Apple Diagnostics with a processor upgrade installed. However, OWC performs real-world load testing on each machine to ensure it is in perfect working order before shipping it back to you.
