After the the last software update initialisation takes a long time. (MAC book air)

After power on nothing happens for around 30-45 sec.(basically much longer than it used to take) (only the start up sound plays right after power on, thats the only way to know I turned the MAC AIr on). It used to take 5 secs to get to login screen not it takes much longer. Once the Apple logo appears it take like sec to the login screen and stratup is ok, as fast as was before.

But the slow inicialization is really annoying. Its a new laptop only like 2-3 monts old so it cant be harware plus this started happeneing right after the last iOS update (now i have IOS X Y 10.10.3).

It is not a serious problem but very annoying 😀.
