It sounds like the drive in your MBA has gone south. Which year and model MBA do you have? An "a1466" doesn't tell us anything as that can refer to many years of models.

It's likely your MBA has a SSD which may or may not be soldered to the logic board. On some models, the SSD can be swapped out for a new one. In any event, try to boot your MBA from an external source: USB, Flash Drive, etc.

Also, do you have a backup?

i believe its a 2013 a1466 emc2925 i tried booting from usb and it just stuck on apple and loading bar.. i tried this hard drive in another mac and it worked fine, i installed mac os on the drive and it worked fine on another mac ? Actually i can hear the installers voice from the mac osx installation usb but screen is just stuck on the apple screen with the laoding bar ! weird!

You may be able to pick out which of the MacBook Air a1466 models yours might happen to be from the list here:
Lookup Mac Specs By Serial Number, Order, Model & EMC Number, Model ID @ EveryMac.com

What exactly is the USB thing you are trying to boot from???

And I'm wondering what the installers voice is that you are hearing.???

I sure hope it's nothing like the old Albert in a tobacco can calling to be let out.

That model has a SSD that’s able to be removed and replaced. Check with OWC for replacement.

Then maybe it's the SSD cable that so many seem to mention replacing???, or God forbid, the motherboard's SSD circuitry has gone kaput.

I agree with Patrick about the logic board that could be the problem. I don't believe your model MBA uses a cable to attach the SSD to the logic board. Isn't it a plug in blade type SSD? You can lookup the info and maybe some troubleshooting tips at iFixit: The Free Repair Manual.

im thinking the same thing the ssd connector to the board or can it be a video / gpu issue? i mean when i press a key i can hear the sounds.. but just stuck on the apple logo and full loading bar..Can it be any other chip on the board ?

Try turning your computer on while connected to an external monitor/TV via HDMI and see if it does anything.

 

[nicktheslick1]

i think i already tried that but ill try again.. anything else it can be?

Are you sure you are trying to boot into safe mode correctly?

 

[nicktheslick1]

im pretty sure i did but just in case im doing it wrong , how do u boot in safe mode ? the only thing it boots to is command s..

 

[IWT]

The method of booting into Safe Mode depends, to some extent on the Mac model.

If you have a Mac with a chime, reboot the Mac and immediately after you hear the chime, press and hold down the Shift key until the Apple logo appears. It will take longer to boot into Safe Mode.

If you have a silent Mac, then things are trickier. Reboot and very carefully watch the computer screen. When it goes from black to dark grey, press and hold the Shift key as above.

If, however, you have a wired keyboard or if you attach your magic, wireless keyboard to the Mac via USB - this makes the wireless keyboard become wired - then you can hold down the Shift key right from the beginning of the reboot.

To get out of Safe Mode, simply reboot in the normal way.

i tried safe mode and same issue guys apple logo and full loading bar and s
thats it.. if i press any key i can hear sounds

 

[nicktheslick1]

i did some research and i believe i need to do a reinstall of the SMC firmware and maybe PRAM to?? Doesnt one of those control the screen and boot up ?

Here is how to reset the SMC: How to reset the System Management Controller (SMC) on your Mac - Apple Support

And the NVRAM: Reset NVRAM or PRAM on your Mac - Apple Support

Good luck with the reset.

 

[nicktheslick1]

i tried both and nothing.. possible those chips need reflashing? can i reflash the firmware on the smc or pram?

I am puzzled by the "sounds" and "voices" you are hearing. When I have installed the OS on my Macs all I get is a chime, and maybe a tone for when it completes. NO voices. So if you are hearing voices, I'm wondering where you got the installer and if it has been hacked.

I don't think you can re-flash those devices. Apple may be able to, but I seriously doubt they are the problem, unless the installer WAS hacked and now has somehow written into the ROM of the SMC/NVRAM. If that's the case, you may have to go to Apple and pay whatever it takes to get control over your system.
