What can I do with saving a "web archive" or "page source"?
If I save a web page as "web archive" or "page source" will it save that webpage's video inside that save so that I can watch the video later offline? Or is there some way to do this in case the online video is deleted later or becomes unavailable?
P.S., this is about my iMac, but I'm not sure which of the two I have listed below. I only have ever had one.
iMac, macOS 10.13
