I've struggled to find the answer to this and have come across differing opinions on it--apologies if this is a duplicate question that's been previously answered--I didn't see any results in my search. Will the new LG 5K display allow me to connect a Thunderbolt 1 drive, with an adapter, into one of the three USB-C ports on the back? The Thunderbolt 3 port will be in use going directly to my MacBook Pro so I can't connect it there and am really hoping to only have the single cable going to my MBP. Here's what I'm hoping will work LG 5K Display Thunderbolt 3 port ---> MacBook Pro USB-C port ---> USB-C to USB-A dock for keyboard/dvd drive/USB Hub USB-C port ---> iPhone (with USB-C to lightning cable) USB-C Port ---> Thunderbolt 1 External Drive (with Thunderbolt 1/2 to Thunderbolt 3 adapter) Apple's chat agent said it would work, but I've read elsewhere that it won't. Any help is appreciated.
