OK - I understand. Sounds like I need to purchase another adapter. This laptop only has what I think are called Thunderbolt drives. So the USB-A plugs directly into the Thunderbolt drive & my thumb drive into it.
Is that correct?
No. The MacBook Air has two multi-function ports, with USB-C connectors, that support
- Charging
- DisplayPort
- Thunderbolt 3 (up to 40 Gb/s)
- USB4 (up to 40 Gb/s)
- USB 3.1 Gen 2 (up to 10 Gb/s)
When you plug something into one of those ports, the Mac and the accessory negotiate which protocol(s) to use. Thumb drives have no idea about Charging, DisplayPort, Thunderbolt 3, or USB4 (yet). They're going to want to "speak" USB 2, USB 3, or USB 3.1 Gen 2.
That will be true whether the thumb drives
- Have USB-A plugs (only) – in which case, you'll need some sort of USB-C to USB-A adapter
- Have USB-C plugs (only) – in which case, you can plug them in directly
- Have both USB-A and USB-C plugs (like a thumb drive I have on my keychain) – in which case, you can plug in the USB-C ends directly
Apple likes to call the ports Thunderbolt ports – because Thunderbolt is an optional, high-end feature (found on virtually every Mac that has a USB-C port), and they like to show it off for marketing purposes. But a lot of your everyday uses (like connecting a USB thumb drive, or connecting a monitor with a resolution of 4K or less) don't involve Thunderbolt. Thunderbolt is just something that's nice to have in reserve for when you do need it.
