I have an older Intel MacBook Pro 16" with 4 USB-C ports, running Tahoe I get this message, any ideas to resolve or is my Mac too old to support this? |

Hi @mrplowuk, thanks for trying it out. It's not that your Mac is too old, it's the chip. Intel Macs drive their USB-C ports through Intel's Titan Ridge Thunderbolt 3 controller, and the cable and power data WhatCable reads (USB-PD state, e-marker info) isn't exposed by macOS on that controller. There's no public API to get at it, so there's unfortunately no workaround. WhatCable needs Apple Silicon (M1 or later) to read this. So the 16" Intel MacBook Pro can't be supported, sorry. Tahoe being installed doesn't change that, it's purely the hardware. |
