Curious about using Thunderbolt
I have a new iMac M3 operating on Sonoma 14.1. It is becoming time for me to set up a system for adding printers and other peripherals. I have received good advice regarding adaptor cables that will transfer from USB1 to USB3. I had not previously heard of Thunderbolt. What is it? Is it merely a different kind of USB3? What are its virtues? Why do some people prefer it? kathleen
