Thanks for your prompt response. I'm sad to hear that there is no support for Apple. I did click on your link (http://www.dell.com/support/home/us/en/19/product-support/product/dell-u2718q-monitor/drivers) and it sent me to the support page for the U2718Q, not the UP2718Q.
If I visit the UP2718Q support page (http://www.dell.com/support/home/us/en/19/product-support/product/dell-up2718q-monitor/drivers) it does show that the monitor does support Mac OS, but no drivers nor software are listed for the monitor.
If you find out any new information regarding macOS support for this monitor or any way that I can use this monitor productively with macOS please let me know.
I am in the same boat as JOHAN12, except I actually bought the monitor. Any chance I can get this working with my MacBook Pro 2016 (USB-C only)? Zero connectivity so far. Thanks!
