What we have to say

Bugs like these often go unnoticed but, they shouldn’t. We know that not everyone uses a scanner these days but, what if you ever need to use one. So, we believe Apple should take notice of these smaller bugs and try to fix them ASAP.

As of now, Apple has only provided a temporary solution for this problem but, with the macOS Bis Sur’s update on the way, Apple finally might be able to solve this bug permanently.
