I have a MacBook Air and my daughter has a MacBook Pro. I am currently running Catalina; she probably is. In my Photos I have some videos, and about to get another, that I would like her to save and view. I am having all kinds of difficulty trying to find instructions on how to send it from my Mac to hers. Tried email, but the files are too big to go. When I try to find a tutorial to follow, I end up with semantics problems. Some think "transfer" means I want to send my files to a new Mac I just bought. Others end up being on iPhone/iPad to Mac. I just want a simple way for her to see them. I suspect there is some way to send it to her (short of mailing a USB stick). I keep running into "sharing" files through iCloud (both of us have that). I know email is turning out to be too complicated. Please, what is a simple (for I am old and not very tech savvy) way to do this?
