The April 2014 update of Apple's 13" MacBook Air features refreshed dual-core i5 and i7 processors, plus slightly increased battery performance.

A1466 - Start on delay

Hello.

My Macbook Air, A1466, when it start it takes around 10 seconds to be shown apple logo.

Fan is exactly 3 times warming up, spin-stop-spin-stop-spin and proceed boot.

Do you have any idea why it was doing like that?

Thank you for kind answers in advance.

I'm wondering if you have a power issue as you appear to be loosing PRAM/NVRAM settings

Try going to start up disc in the system preferences and unlock and select the internal SSD.

I have had this issue arise a few times and have come to the conclusion that the system is searching for boot devices which is causing the delay. If this didn't solve anything then it can be possible there is another issue and a SMC / PRAM reset might be helpful as mentioned by Dan.
