My late 2017 13" MacBook Pro with USB-C ports works fine with my 5DSR and 5DIV using EOS Utility. But, it is not recognising my M5. Further, when I put its SD card into a card reader, the card does not appear on the desk top. I have tried resetting SCM and NVPRM but to no avail.This is terribly frustrating as I have a trip on Wednesday and was hoping to take the smaller laptop rather than my old 15" MacBook Pro, which works well (standard USB ports). Ant advice please.
