can a previous owner of a macbook air potentially see what i’m doing ie. steal my assets
i plan to trade on my renewed device . i just worry the old user can possibly steal info or even assets if i were to trade crypto and stocks on here, i have a hardware wallet i’ll be storing my crypto on but i figured this would be safer bet then doing it on my phone or a cheap chrome book pos laptop . anyone’s thoughts and preventative measures i can take? sorry y’all just a worry wart when it comes to these things
MacBook Air 13″, macOS 10.15
