Hello - Just got the new 27 inch 5K base model iMac. Moved files over from old MacBook Pro. Every time I boot the new iMac, I get the "printhelper quit unexpectedly" error box with option for send information to Apple. I have re-installed the OS based on Apple's recommendations. No help. I do not have any printers set up in the Preferences Printers section. Apple is saying I may need to bring it to the Apple store for diagnostics, but that is 100 miles away for me. Thanks for any advice.
