Sembra che stia avendo problemi persistenti con la connettività Bluetooth, specialmente dopo aver svegliato il mio Macbook Pro da un lungo sonno.
Ho un altoparlante che si spegne automaticamente dopo un certo periodo di inattività, e il mio caso d'uso è tipicamente aperto sul portatile, accende l'altoparlante e quando il driver Bluetooth funziona normalmente, si ricollegheranno automaticamente.
Tuttavia, il problema sembra essere che le mie periferiche Bluetooth non si ricollegano se il mio Macbook è appena stato svegliato da un lungo sonno.
Dopo aver cercato in giro, ho trovato questo script per riavviare le estensioni del kernel bluetooth , ma non sembrava lavorare su Yosemite.
Ecco cosa mi ha dato sudo tail -f /var/log/system.log
dopo aver eseguito un kextload
e kextunload
