Have downloaded the Adobe app--"Adobe colour print utility". this is an app that allows you to print off a colour test chart without any colour managment from your printer or adobe photoshop. This chart is then forwarded to the makers of the paper you use, in my case Permajet, who then make a bespoke profile for you. My problem is that the app will not open properly. Have read on the internet that this app is not suitable for os Catalina so is this also the case for Mojave. Have contacted Apple who went through it with me, even had control of my screen, and they confirm it is not the operating system but must be the app. This app was made in 2010 so does it need an update. Anyone else experiencing this problem.
