I have Time Machine backups but the external drive for the old computer has USB ports while the new IMac will have Thunderbolt ports. This makes connection incompatible since the ports are different.
The Thunderbolt ports on the 24" M4 iMacs are USB ports – USB4 ports, with USB-C connectors, which support
- USB 3.1 Gen 2 (up to 10 Gb/s)
- USB4 (up to 40 Gb/s)
- DisplayPort
- Thunderbolt
They adapt to whatever you plug into them. So if you plug in a USB 3 device, the Mac and the device speak USB 3, and the device does not need to be aware of USB4, or DisplayPort, or Thunderbolt.
You can plug USB-A devices into one of these ports with the help of an Apple USB-C to USB Adapter. If you have bus-powered drives with Micro USB 3.0 B sockets, you can get USB-C to Micro USB 3.0 B cables to substitute for the USB-A to Micro USB 3.0 B cables typically bundled with such drives.
