Hello @Paule39
As far as I know there have been no changes, I am waiting to hear back from the development team to confirm this.
- Has Safari updates in the last 3 months?
- Do you get the same issue with other browsers (FireFox/Chrome)?
- Can you follow the Apple support article I sent you earlier with a csv file you already have to change the default program/file association?
I did a quick search on the web for issues such as this and it seems more to do with Safari’s handling of CSV files
Example (please be aware this is a 3rd party website and not related to QuickFile)
