Frequently Asked Questions
Why does my PDF reader show a blank white window when saving on a Mac?
This is often caused by a known bug in how the software interacts with the macOS file dialog interface, specifically when fetching online storage options. Disabling online storage prompts in preferences often bypasses the bug.
Will I lose my form data when the PDF application freezes?
Yes, if the application completely freezes before you have successfully saved the document, any unsaved data entered into the fillable fields may be lost when you force quit.
How do I report persistent freezing issues?
If updating the software doesn't work, contact official support and provide them with a screenshot of the blank window, your application version number, your macOS version, and a description of the PDF file.
Are there other programs I can use to share fillable PDFs without freezing?
Yes, alternative office suites like WPS Office feature built-in PDF tools that allow you to read, fill, save, and share PDF files smoothly, avoiding the specific bugs present in other applications.
