Element (24, 46, or 88) doesn't power up when I connect it to my display monitor or my MacBook.

Thunderbolt devices such as the Apogee Element will only work when connected to true Thunderbolt ports. Be careful not to mistake a Mini-Display Port for a Thunderbolt 2 port or a USB-C port for a Thunderbolt 3 port:

  • If you're trying to connect to a monitor display, confirm that the display has more than 1 Thunderbolt port. You can't connect more than one 1-port Thunderbolt device in a Thunderbolt chain. The display will need an upstream Thunderbolt port to connect to the Mac or another 2-port Thunderbolt device in a chain and then it will need another Thunderbolt port for you to connect the Element to. A couple of common mistakes people make are mistaking Mini-Display Ports with Thunderbolt 2 ports since they look exactly the same and confusing USB-C ports with Thunderbolt 3 ports since they look exactly the same. For example, the LG Ultrafine 5k monitors have 1 Thunderbolt 3 port and 3 USB-C ports. All 4 ports look alike, but only 1 of them is a Thunderbolt 3 port. You should always look for the Thunderbolt icon next to any Thunderbolt port. With the exception of the new MacBook Pros, any Thunderbolt port will usually have the Thunderbolt icon next to it.

  • If you are connecting to a Mac with a USB-C port, make sure that the port supports Thunderbolt, as Thunderbolt devices will only work on Thunderbolt ports (even if they're the USB-C style ports). Some USB-C ports only support USB.
