I have the same problem on a MacBook Pro (13-inch, Mid 2012) with DPP Version 220.127.116.11: is there a way to disable usage of graphics processor before starting up dpp 4?
I don't know if this would solve the problem, since DPP runs fine on a MacBook Pro (Retina, 15-inch, Mid 2015) <snip>
It appears that DPP 18.104.22.168 is the latest version that will run on my Late 2013 iMac, which came with OS X 10.9—or maybe 10.8—preinstalled. All later DPP versions AFAIK require
OS X 10.10, 10.11, macOS 10.12, 10.13 PREINSTALLED – UPGRADED MACHINES NOT SUPPORTED
(Quoted from Canon's documentation—emphasis mine—and verified by Canon Support, who were unable to provide a workaround for me.)
Your Mid 2012 MacBook Pro (like my iMac) would have come with an unsupported OS (OS X Lion, in your case) preinstalled—and therefore will not run DPP Version 22.214.171.124. But the Mid 2015 MacBook Pro would have come with an OS (macOS Sierra) that meets the DPP 126.96.36.199 OS requirements—and therefore is able to run DPP 188.8.131.52.
