Output: ` Target Display Mode: send_byte(0x06, 0x0300) fail: 0x00 MVHR: read len fail

read_smc get_key_type error

send_byte(0x06, 0x0300) fail: 0x00 MVMR: read len fail

read_smc get_key_type error `

I get the same output in Ubuntu as well. Device is connected from Host DP to Mac miniDP.

I have the same problem. Any fixes yet?

This seems to be related to the iMac missing the display controller, eg TDM isn't supported. I can't verify this though.

Without further checking, but possibly related to https://github.com/gpdm/tinycore-targetdisplaymode/issues/9
