If you cannot download CSV archives on Safari, namely you cannot download your form submissions in CSV at all, you’ll need to tweak your browser a bit. To download the CSV file on Safari, follow these easy steps below:
1. In Safari, go to Safari → Preferences and click on the Privacy tab.
2. Deselect the checkbox before the Prevent cross-site tracking option.
3. Deselect the checkbox before the Block all cookies option.
After you have applied these changes, you will be able to download your form submissions in CSV from now on.
