My wife has an old Macbook laptop, old being the keyword here. It powers ON, and almost everything works fine, except the battery, which is completely dead thus it works directly on mains power. To see if it can have any practical usage in the current time, I tried accessing Internet through the Safari and tried updating it but neither happened. Posting below the phone pics clicked of the system's config and error messages. Please let me know if it can be brought up to the code of some degree of usability and if so then how. Attaching the pics below.
