piace così (assumendo che tu salvi la patch in un file chiamato MagicKeyboard.patch
):
sudo sh -c '(cd /; patch -p0) < MagicKeyboard.patch'
e ricostruire la cache di kext usando:
sudo kextcache -f -update-volume /
Dopo il riavvio, la tastiera Magic dovrebbe essere completamente funzionante quando è collegata tramite cavo.
