How to Fix Preview and Quick Look issues on macOS Mojave

macOS Mojave 1014 is one of the lightest and best-operating systems for Macintosh including lots of best features. It was morning June 2018 that Apple launched the macOS Mojave Beta version for public and developers. It’s being inspired by the desert at night time, macOS Mojave is the first Apple operating system that didn’t use that mountain-themed name.

The best feature in macOS Mojave 10.14 is the system dark mode that contains overall the system interface look. After applying the dark mode on macOS Mojave it will cover the following apps like Mail, Calendar, iTunes, Xcode, and more dark mode.

However, Before I was using macOS Catalina 10.15 on my computer, but a few days I have installed macOS Mojave with the replacement of macOS Catalina 10.15. Due to that, I faced a small issue while opening a JPEG image or high-resolution image.

Most of the users faced this issue at the time of using macOS Mojave. When you want to try to open any image with a simple preview mode, or “Quick Look Preview” then you will get stuck and it will start loading and it won’t open the image.
