Tried to transfer files from my MacBook Air (2019) to my new MacBook Pro (2020) as I want to sell my MacBook Air. Got a failed authentication error message then tried to reset SMC as I read on one of the discussions here that's what I needed to do, in the process I ended up not being able to log back into my MacBook Air with my password. No error message popping up, just won't accept my password. Please help!
MacBook Air 13″, macOS 11.4
