how to move more datas to computer

There are thousands of programs on the internet that can do this. The most efficient is MEGA, which will grant 50 GB to your computer once you create a MEGA account.

Another thing that you could do is transfer files to another computer (A desktop would be recommended because deaktops almost always have a capacity of at least 2 terabytes). This will free some space.

You could also delete unwanted files or just simply use a mac cleaner (e.g. MacKeeper) to clear out junk files.
