If you are planning on selling the computers it is best to do a erase and reinstall of the OS. Depending on which macOS you are running, when you erase the drive you can specify to erase by writing zeros one or more times on the drive to ensure that all data is erased. This is only useful for computers that have a spinner drive, SSD drives don’t need to do that kind of erase.
