For my internal notes, click my name and private message me both of the U2518D service tag numbers.
For Dell to troubleshoot, you need to test the U2518D's on a dedicated Windows operating system PC to see if the daisy chain issue is present.
We can see on the U2518D drivers page and also in the U2518D User's Guide that there is no mention of the proprietary Apple operating system or hardware. You should read the U2518D threads on the Apple Forum and see what other Apple users have done as far as Apple PC troubleshooting and possible Apple proprietary cabling to purchase. If need be, sign in there and start a new thread.
After searching a bit in Apple's forum I have found that although Macs have support for MST, macOS does not support daisy chaining for DisplayPort, only for Thunderbolt displays.
