Hi Color Sync Users This is about display color management in multi-user educational Mac labs. This is not an easy task. We run three colour managed labs in our photography department at our university. Students will change the brightness of their displays. And move them out of their calibrated setting. And without intervention, all subsequent users of that computer will inherit their choice for the display brightness. And not only that, the default setting for a new user account is for the display is to automatically adjust brightness using the ambient light level. When you running a color managed at the ISO recommend brightness of 32 lux, that makes for a very a dim display. And new users of a machine will not by default inherit the custom ICC display profile we build. We manage all this nonsense with log in scripts. That touch and set user setting in the display panel in System Preferences. Tools that load a selected display profile. Scripts that reset the display brightness to the level recorded at the time the custom profile was built. Scripts that then watch the display brightness setting. There are no Apple tools to manage these sorts of things. So our Mac IT specialist uses modified tools from Git Hub projects to do this. Like Joey Korkames ddcctl project we use for managing Mac display panel and brightness settings. And Tim Sutton has made a tool for selecting the custom display profiles. Plus there are other custom tools our Mac specialist built himself. We would both prefer if there were proper Apple MDM tools / Apple support for managing this sort of user display setting related stuff. As the Mac OS matures it becomes ever more secure, as it should. But then these back-door style tools keep breaking with OS updates. And we have to test and often re-engineer the tools every OS upgrade. This year the tool that turns off the user setting to automatically adjust the display brightness stopped working. If we can’t get it working before the students get back, we won’t be able to colour manage their labs. That’s a big deal for us. REQUEST If anyone on Apples ColorSync team is reading this, can you please go in to bat on our behalf and ask that Apple create some proper MDM tools (or something of the sorts) for businesses like ours that need to manage their users display settings. And if other list member who manage colour managed labs in an educational environments want to chip in with their experience I’d love to hear that too. Thanks Peter Miles
