I've been trying to flash this Macbook Air A1466 2014 motherboard for some time now!
Any help would be greatly appreciated!

The 1466 can be a pain in the a$$. Disconnect the battery, connect the magsafe and let it run for a Min or so. Connect the pi and it should be good to go!
Keep me posted!

So basically the same issue is occurring. I get a good connection with the clip and the board and the Pi wont boot. There is no light. If it has a bad connection it will boot and flashrom shows No EEPROM/Flash device found.
MBA Easy Flash that I got from this site. I plugged in the magsafe for a few min and if I hold down on the clip to make sure it has a good connection the Pi will not turn on. Am I doing something wrong?CygnusX1 wrote:

Which clip are you using?

Connection from the SPI to the clip is this:
Pin1 - 24
Pin2 - 21
Pin3 - 17
Pin4 - 25
Pin5 - 19
Pin6 - 23
Pin7 - 17
Pin8 - 17
Also measured the ground and power and I get 3.3v

What version of the PI are you using?!

Raspberry Pi Model B
Connection from the SPI to the clip is this:
Pin1 - 24 CS
Pin2 - 21 MISO
Pin3 - 17 WP
Pin4 - 25 GRD
Pin5 - 19 MOSI
Pin6 - 23 SCLK
Pin7 - 17 HOLD
Pin8 - 17 3.3V
Cables need to be no longer then 20cm
You can wire pin 3, pin 7 and pin 8 to 3,3v and be sure to have at least 2.4amps

I even tried with either or bot power supplies disconnected and nothing. I have even tried 2 different clips! no joy. Since it is looking for a 4 pin combination, I am just going to brute force it.

is your macbook iCloud locked, or are you just fighting an EFI password?
reverendalc wrote: that's curious. the [?] screen happens when somebody remote erases via iCloud, but you should certainly expect the EFI lock screen when attempting to boot with ALT.
can you clear the NVRAM with CMD/OPT/P/R, or boot single user or safe mode?
if those don't work, but it doesn't greet you with the padlock, next i would connect a USB keyboard to be sure that you're actually sending ALT/OPT when pressing the keys.
do you have another mac or a usb enclosure you can use to install OS X on that ssd, and then try to boot the mac from it?
