Here's the thing, the right shift key of my macbook is stuck, so it always boots in safe mode once I turn the machine on. Worse, I cannot log in since my password has lower case letters.
I tried resetting the NVRAM by holding Command - Option - P - R and also went into the disk utilities, however nothing I can do there helps.
I looking for a way to disable the right side shift key or alternatively enable the bluetooth via command line, since I have a wireless keyboard, but I cannot make either work.
I woke up today and the key was working fine. However I do not trust on it. Probably when the MacBook gets warmer it will stuck again.
I downloaded a software called KeyRemap4MacBook, which can be downloaded from here. I followed this tutorial in order to deactive the key, this is a temporal fix while I make some saving to buy a new one.
