Can I use an Thunderbolt with an adapter or hub with my devices?
⚠️ Yes, but the results may vary, so we cannot guarantee that you will get the same performance that you would without a hub. The more devices you have connected to a hub, regardless of quality, the more likely your connection is to degrade. You can use a Thunderbolt adapter for your Thunderbolt connection.
