can a previous owner of a macbook air potentially see what i’m doing ie. steal my assets

As I understand it, you purchased a Mac that was previously used by someone else. Provided the seller (including all previous owners, should that be a factor) complied with all the requirements in What to do before you sell, give away, or trade in your Mac - Apple Support, they will no longer be able to do anything with it.


If you are planning on trading it in, be sure that you comply with those requirements. Encrypting its startup disk with FileVault ensures its contents will remain inaccessible and useless to anyone else.
