macbook 2014 locked in recovery mode
i recently just bought this 2014 macbook pro from the pawn shop (gold & pawn) and its runs slow and restarts sometimes. ive been trying to factory reset it or clear drives, or reinstall OS but its locked in recovery mode and its not the same password as the log in... my cpu percentage is way up there at about 28-30% i cleared all caches and history ect... and it also says on icloud theres to many accounts... im really confused and need this for my business... and its my last resort. please help & thank you!!
