My Macbook Air model a1466 has been having a weird issue. The trackpad and keyboard do not work but only after boot. I can turn it on using the power button and I can boot into single user and verbose mode but as soon as the login screen comes up, my keyboard and trackpad stop working. I have tried a factory reset but this did not fix my issue. Any suggestions?

Hi,
Try to reset NVRAM.
How to reset NVRAM or PRAM on your Mac - Apple Support
Or try to boot in Safe mode,
Use safe mode to isolate issues with your Mac - Apple Support
Neither of these fixed my problem. What's weird is that I am able to reset the nvram and boot into safe mode (which requires a working keyboard) but as soon as I get to the lock screen everything stops working.
I had the same thing with my MacBook. Searching the internet shows that it might have to do with FileVault and not having an external keyboard/mouse connected. Do you use FileVault on you Mac?
For me the following sollution works:
- Go to System Preferences/Bluetooth/Advanced...
- When I saw the problem, in my settings there I only had the last option ("Allow Bluetooth devices to wake up this computer") enabled. Since I've switched each setting (so enabling both options about the "Open Bluetooth Setup Assistant at startup..." and disabling "Allow Bluetooth devices to wake up this computer"), I can simply boot my computer with a responding keyboard and trackpad.
(I'm still experimenting with these settings.)
I hope this helps you too.
Kind regards!
I have been experiencing exact same issue with the same model.
Did you ever find an answer? I have the same issue with the same model.
