Why does it mention USB 3.2 (i.e. 20 Gbps) at all if it's for Macs? I thought Macs only support 10 Gbps and 40 Gbps, but nothing inbetween?

(which is inconvenient because USB 3.2 Gen 2x2 20 Gbps external SSD cases are much cheaper than USB 4 cases for now).

Also, he is calling a binary a script, which i find suspicious. This task looks like it should have been a script.
