Cannot Open Files from Desktop/Downloads/OneDrive on macOS
Problem
When using Oxygen XML Editor on macOS, the application cannot open files from Desktop/Downloads/OneDrive.
Cause
Sometimes, macOS shows a popup about allowing the application access to some special folders (e.g. Downloads or Desktop), and unless you explicitly agree, it will leave it unchecked (the app does not allowed access). The popup can go unnoticed and disappears after a while, so it is easy to overlook it and the application will not have access to that folder.
Solution
Go to the macOS
. You should find Oxygen in that list and the folders you were
prompted to access. Check the box for the folder (i.e. Downloads or Desktop), if there
is one unchecked.Note: If that does not work, look at "Full Disk
Access" from the same Privacy tab. Add Oxygen there so that it has full access.
However, only use this method as a last resort.
