Hi,

I own a 2011 13” MBP on High Sierra.

A couple of months ago, the left shift key got stuck due to a few drops of water.

This is a quite common problem and the recommended solution is to deactivate it with a tool that remaps the keyboard. The computer also boots in safe mode but this can also be prevented by pressing some other keys at startup.

However, my computer recently crashed and is now restarting on another partition, an older one that remains from a Windows dual boot I had years ago but which is now disfunctional. It just shows a Windows 10 BSOD.

I haven’t found a way to access the startup manager, the recovery mode or to start it normally yet. I’ve tried every combination but the addition of shift key turns them into a shortcut which is not recognised.

I’m gonna try to burn a bootable key tonight but I don’t think I’m gonna manage to boot from it if I can’t select it.

Do you know of any method to fix this, apart from maybe opening the machine and disconnecting the built in keyboard?

Other options I’m considering:
- plug an external keyboard (I don’t have one at hand)
- boot the hard drive in target mode on another FireWire Mac (not sure if still supported)

Any idea? I really don’t have access to anything apart from a BSOD.
