Someone please help. I just want to join two mp4 files. NOT ONE OF THE 20 OR SO 'FILE JOINERS' ON OFFER WORKS. I don't want to make a movie, convert to pdf, ALL I WANT TO DO IS JOIN TWO FILES, SIMPLY. For a PC user, hjsplit does this, effortlessly.
That's what's on my mind. Why is Apple simply unable to provide this simple, simple service?
MacBook Air (2018 or later)
