Have just been forced by a failed hard drive to adopt El Capitan. EyeTV 3.6.9 recommended, and downloaded. Autotune produces a grand total of 0 channels where once there were 117. Archived material seems playable, but that's not what I paid for. Currently it takes Geniatech three days - or so they say - to respond from their Asiatic strong hold, and it seems their default reaction is to blame Apple. Globalisation might be OK in the hands of honest traders, but they seem to be extinct these days.
