Prova questa soluzione per il problema di Sky go su Mac, già pubblicata in un vecchio post 2014 di questo forum.
A me ha funzionato tempo fa, e l ho conservata per ogni evenienza.
Delete the Sky Go app. Launch Finder, select Downloads then delete ‘SkyGoInstaller’. Launch Finder again, select Go (at the top of the screen), then Computer. Select Macintosh HD. Go to Users > [yourusername] > Applications then delete the Sky Go app. Then go to Library by Open Finder. Click "Go" on the menu bar. Press and hold the “option/alt” key. Click the "Library" shortcut which appears. Then navigate to the relevant folders (Application Support, Caches or Preference) and delete all SkyGo folders and files referencing Cisco player Reboot your Mac and then download and install the Sky Go app again.
