Trying to flash lineage OS to my Samsung galaxy s6 but for some reason the Mac cannot detect my device.. The only way I can cannot it to transfer data files through USB is by enabling USB debugging in developer options but I never had to do this before. I have bought a data transfer cable thinking this could be the problem but it wasn't. I'm trying to flash lineage via heimdall which works in conjunction with heimdall through download mode. The command to see if heimdall is working on device is heimdall print-pit but I keep receiving an error " failed to connect compatible download mode device then I tried again and the error was: failed to send! Releasing Device interface" anyone know what could be the issue here and how to resolve it?

Thank you

Anyone?? Advice would be much appreciated.
