Gentlemen, Thank you very much for your comments. Adobe Color Printer Utility does work but doesn’t always center and yes it will not print CMYK targets. It spits out a blank page. All I wanted to do was output a 2 row GRACol control set there in ACPU and then also output form i1Profiler 3.2 and compare the two. I sent a small RGB target instead. With the Mac I can at least print with, Last Settings Used. I printed from ACPU and then looked at what was showing up in i1Profiler 3.2 to help figure out those settings. Delta E values were very encouraging. My other question was about Printer Dialog windows. ACPU and Photoshop have a standard printer dialog interface, but i1Profiler and many other apps in Mojave 10.4.6 do not, Preview and ColorSync Utility included. All the selections are available at one time and nothing gets grayed out. What I have found is that the Printer Dialog Extension (PDE) gets blocked by, Hardened Runtime’s library validation. I guess what I need is to unblock, Disable Library Validation Entitlement. Does anyone know how I would do that in Xcode? I tried working on the P800 Driver but now think that was the wrong approach, I should look at an application. Is anyone else seeing Printer Features, and all selections in one submenu, instead of, Printer Settings, and a normal dialog window? Please see a pdf to show the printer dialog windows; https://www.lenzart.us/PDF_link <https://www.lenzart.us/PDF_link> Thanks, David
