So my MacBook Air was working normally till yesterday. It was laying on my table and as I wasn’t using it it went to sleep mode. At one point I heard a start-up sound but I ignored it. Later when I tried to use it again and turn it on nothing happened. I could only hear fans inside working loudly. Now sometimes I hear them, sometimes nothing happens at all. I tried resetting SMC and NVRAM but it didn’t work. Does anyone have experience with similar problems or any idea for what I should try next?
It sounds like your system was in the process of an OS update. Restart your system make sure you have a wired connection to the internet (not WiFi) as well as connected to a MagSafe adapter (powered). Then let it be for about a hour or two, it should restart again on its own once the systems firmware has been updated which is what I suspect was taking place when you stopped it. If that didn’t work see if you can put the system in Safe mode when you restart it.
