Mi dispositivo: Macbook Pro a principios de 2011, Yosemite 10.10.4
Desde hace poco más de un mes, tengo algunos problemas con mi trackpad.
Al principio, comenzaría a revertirse con una velocidad muy rápida (básicamente, es casi imposible hacer clic en el lugar que desee. Ocurría de vez en cuando, tal vez 2-3 veces al día, a veces no había ningún problema durante 1 o 2 días. Un reinicio lo arreglaría.
Desde una semana o dos, el trackpad deja de responder durante unos segundos antes de revertirse a alta velocidad, y algunas veces (en realidad, muy raramente) vuelve a la normalidad.
Intentó restablecer la PRAM, restablecer el SMC, desconectar y volver a enchufar la batería, limpiar completamente el trackpad, desconectar y volver a enchufar ambos extremos del cable del trackpad.
Siempre vuelve. Desde hace unos días es cada vez más frecuente. Como de costumbre, un reinicio lo corrige, pero ahora, podría volver 2 minutos después de un reinicio.
Acabo de hacer una reinstalación (solo una reinstalación, manteniendo todos mis datos y aplicaciones), y no se corrigió en absoluto.
Recientemente, también noté que el teclado podría no responder por poco tiempo, pero pensé que podría deberse al uso de la CPU o lo que sea, pero empiezo a pensar que es un enlace. Aunque no dura mucho en absoluto.
No sé si es un problema de software o hardware. Estaría bien cambiar el trackpad y el cable si estuviera seguro de que eran el problema.
Aquí están los registros de la consola cuando ocurre el problema.
