One problem that Mac 911 can always count on: The complexities of using old Apple monitors to work with new USB-C-equipped Macs.
The 2015 and later MacBook uses USB-C for USB 3 and DisplayPort. The newer MacBook Pro and iMac models pass Thunderbolt 3 over USB-C, along with DisplayPort and other standards.
I recently updated our best advice and knowledge for Apple’s Mini DisplayPort and Thunderbolt 2 displays. For older Apple monitors that relied on DVI—sometimes requiring a dual-link DVI setup for its largest displays—I had yet to find a solution in a single product, with adapters, or from readers who had solved it.
