Frequently Asked Questions
Why does Acrobat crash specifically after a macOS update?
macOS updates often introduce new security protocols or change core system libraries. If Adobe Acrobat is not updated to support these underlying changes, specific functions like creating security envelopes can trigger system conflicts and crash the application.
How do I find the crash log for Adobe Acrobat on Mac?
You can find crash logs by opening the 'Console' app on your Mac (located in Applications > Utilities). Check under 'User Reports' or 'Crash Reports' for files starting with 'Acrobat' to see detailed error codes.
Is there a way to secure a PDF without using the security envelope feature?
Yes, instead of generating a security envelope, you can directly encrypt the PDF document. Go to File > Properties > Security in Acrobat, or use the Protect tab in WPS Office to require a password to open the file.
Does WPS Office support opening PDFs created in Adobe Acrobat?
Absolutely. WPS Office is fully compatible with standard PDF formats created in Adobe Acrobat, allowing you to view, edit, annotate, and secure them smoothly without layout issues.
