That was a good article thanks and may be useful in the future but I would need to be able to connect the two macs. My problem is that I can't find the proper cables to connect the 2 computers: USB A to USB 4 (thunderbolt). All the new mac air has for ports are 2 Thunderbolts. These are not the same as the older Lightning connections.
Macs never used Lightning connectors, except on Magic Keyboards and Magic Mice. Lightning is a small, flat, reversible connector similar to (but not the same as) USB-C. You see it on many iPhones and iPads – although even there, Apple is now transitioning to the newer and more capable USB-C.
Thunderbolt started out on a Mini DisplayPort connector (Thunderbolt 1 and 2). When Intel was coming up with Thunderbolt 3, work on USB-C ("one Ring^H^H^H^H connector to rule them all") was going on. Intel believed (correctly) that Thunderbolt would have more future on USB-C, and so moved it there.
I have to find some adapter to mate the USB A to the Thunderbolts.
Unless you're in the market for a Thunderbolt dock, the type of adapters that you want involve going from USB-C (USB) to USB-A (USB). The fact that your new MacBook Air can speak Thunderbolt on its USB-C ports does not mean that everything that you plug in there needs to understand Thunderbolt. The Mac will adapt to whatever is plugged in as long as they speak a common protocol. In this case, USB.
A Thunderbolt dock could actually add USB-A ports in the sense of "plugging in a USB-A PCIe card" – not just in the sense of "plugging in a USB-A hub".
Note that many Amazon vendors will describe USB-C (USB) or USB-C (DisplayPort) products as "Thunderbolt-compatible" even though their products do not use Thunderbolt. They're trying to reassure Mac users that their products will work with Macs, but these product descriptions often make it harder for people to understand how things work.
I'm also interested in the availability of adapters for sd cards and such.
There are lots and lots of USB card readers. Some plug in via USB-C, and even those that don't can be plugged in with the use of an adapter.
Still, I need my files transferred to the new mac air - I can't believe this can be a problem! Surely there must be some way to connect the standard USB A to the Thunderbolt USB 4??
You can get USB-C to USB-A cables that aren't just charger cables, and that can carry data at USB 3.0 or 3.1 Gen 2 speeds.
I'm not sure if they would be enough to let you do a migration, though. Target Disk Mode used to be quite flexible, but now, I believe that if either Mac is running Big Sur or later (which the new one will be), a Target Disk Mode link has to be a Thunderbolt one.
That would require the use of a $50 Apple Thunderbolt 3-to-2 adapter and a $30 Thunderbolt 1/2 cable to hook up one of the USB-C (Thunderbolt 3) ports on your new Air to the Thunderbolt 2 port on your old Air. If you are going to spend that sort of money, it would make more sense to migrate via an external drive – which you could then repurpose for backing up the new machine.
