so dowloaded smart switch for mac connceted with the provided usb cable ...each time i get failed to connect error ?? Android transfer connects no problem ?
Same here. Problems started after High Sierra updated. Smart Switch can not connect to Samsung S6. Uninstalled Smart Switch several times, but nothing. Any ideas ?
Do you Open a USB debugging in the phone setting? If not, try to open it.
Or find another compatible usb cable to link with PC, and see how it works.
