How to Fix Apple Mac spacebar preview not working

It has only been a short while since the new macOS made its way but several issues have already popped up. While the dust hasn’t settled yet, the users are reporting a new issue. This one is regarding the Quick Look Preview and the spacebar not working. Quick Look Preview is a handy feature, which allows you to preview an image or video without opening it.

Quick Look Preview feature not working for Apple Mac users

In the Quick Look Preview, you need to hover your mouse cursor over the image and then hit Spacebar and let the program do the rest. However, it’s easier said than done. Many users have been voicing their concern that they’re unable to use this feature. When they’re trying to view images through the Quick Look Preview, then it’ll only display a small thumbnail that seems to have been compressed beyond the limits.

As opposed to earlier times when you’d view the video on the preview screen, it’ll only show a small distorted thumbnail in minimal quality. All this has made the feature unusable. With that said, there is a workaround that can help you fix the issue of Quick Look Preview with the spacebar not working.
