Card reader on working on my MacOS Mojave
in system info under card reader it says:
Vendor ID: 0x05ac
Product ID: 0x8406
Revision: 3.00
Serial Number: 820
MacBook Air (2020 or later)
Hmmm, I'm on Mojave right now & have a 2019 iMac, so maybe it should be different, but mine reportds...
Built in SD Card Reader:
Vendor ID: 0x14e4
Device ID: 0x16bc
Subsystem Vendor ID: 0x14e4
Subsystem ID: 0x0000
Revision: 0x0001
Link Width: x1
Link Speed: 2.5 GT/s
Think the boldened part should be on any Mac?
