Brand new mac mini, no custom software installed. When I download ANY file from the internet, it does not appear anywhere visibly on the computer or in the finder. It is just nowhere. If however, I go to the browsers download manager, and click on the file, and then show in finder, it magically appears.
This is so frustrating and I recall this happening on my MacBook Pro as well a few years ago. Never found a resolution then, hoping there is one now.
Additionally, when browsing for files to upload to a website, all files in the browse window are greyed out, until I click on them. Then they are magically selectable. Seems like a related issue.
