Stream Instead of Downloading
Nowadays, there is a trend of downloading movies, pictures, and videos to phone memory. Downloaded data can be uploaded by Mac to cloud storage such as Google Drive or Mac's storage file, allowing you to view it online without the network at any time.
Creating an email and registering on Google Drive is very convenient and saves a lot of Mac space, ensuring videos have sharp images and free storage. So this is the way that you are entitled to enjoy and put into practice.
