We are encountering a download issue in Safari 18.2 on macOS Sequoia 15.2 where file downloads initiated by our AngularJS application (such as Excel exports) are silently blocked. There are no errors in the browser console, and the download does not occur. Interestingly, after testing on Safari 18.3 with Sequoia 15.3, the downloads worked as expected. However, the problem reappeared on Safari 18.4 with Sequoia 15.4. We suspect that recent changes in Safari’s security or download handling may be preventing downloads triggered via asynchronous JavaScript (e.g., AJAX calls) that are not initiated directly by user interaction.
We would appreciate any insights, suggestions, or possible workarounds from the community. Looking forward to your guidance on this matter.
