I always love how there are millions of tricks you can do with your macOS to enhance and power up your daily workflow. Recently, I found out that there is a way to pop out a video and display it anywhere on your screen.
By the way, you must use Safari! Other browsers won’t work. Safari is a browser in every macOS anywhere, so you should be able to find it very easily.
The popped-out video can be repositioned to every corner of your screen. It can be resized too.
