Il mio dispositivo: Macbook Pro all'inizio del 2011, Yosemite 10.10.4
Da poco più di un mese, ho riscontrato alcuni problemi con il mio trackpad.
Inizialmente, inizierebbe a essere ripristinato con una velocità molto elevata (in pratica, è quasi impossibile cliccare da qualche parte dove vuoi. Stava succedendo di tanto in tanto, forse 2-3 volte al giorno, a volte non c'erano problemi per 1 o 2 giorni. Un riavvio lo risolverebbe.
Da una settimana o due, il trackpad non risponde per alcuni secondi prima di essere ripristinato con l'alta velocità, ea volte (molto raramente in realtà) torna alla normalità.
Ha provato a ripristinare la PRAM, resettare l'SMC, scollegare e ricollegare la batteria, pulire completamente il trackpad, scollegare e ricollegare entrambe le estremità del cavo del trackpad.
Ritorna sempre. Da qualche giorno è sempre più spesso. Come al solito, un riavvio lo corregge ma ora potrebbe tornare come 2 minuti dopo il riavvio.
Ho appena fatto una reinstallazione (solo una reinstallazione, mantenendo tutti i miei dati e le mie applicazioni), e non l'ho risolto affatto.
Ho notato recentemente che la tastiera potrebbe non rispondere per un breve periodo ma ho pensato che potrebbe essere a causa dell'uso della CPU o altro, ma comincio a pensare che sia un collegamento. Anche se non dura a lungo.
Non so se si tratta di un problema software o hardware. Sarei a posto per cambiare il trackpad e il cavo se ero sicuro che fossero il problema.
Ecco i log dalla Console quando si verifica il problema.
