Lightning has two data lanes and this cable looks like it’s missing one of them. IIRC devices can use either lane depending on orientation of the plug so that would explain why data transfer was working for you. Does it stop working if you rotate the plug?
If it’s a Mac then it’s not the CPU that’s doing the encryption for the internal drive. Macs have separate hardware for that, the CPU can’t even get the key.
Macs have encryption in hardware in the dma channel for their built-in drives (Intel Macs with T2 and all ARM Macs), so the overhead is negligible on the internal ssd. Macs actually don’t even have unencrypted internal drives anymore. The filevault toggle only affects whether the volume encryption key stored in the secure enclave is itself encrypted or not.
Older Macs and external drives are a different story of course.
I’d go mad too if someone tried to train me on AI created data all the time…
It’s not related to Windows or Linux, but as the article notes, Apple devices that use UEFI are not vulnerable (and current ones don’t use it anymore and therefore aren’t vulnerable either), so I guess that’s where the “Windows or Linux” comes from.
