- macOS Mojave
- Scenario
- Attempting to send a PDF as an email attachment using the built-in email feature in Acrobat.

Update Adobe Acrobat and Restart Your Mac
Installing the latest updates for Acrobat often patches bugs related to the email attachment feature.
Outdated software can cause communication errors between Adobe Acrobat and your macOS mail application. Ensuring both your Mac and Acrobat are updated to their latest versions is the best first step for resolving system integration issues.
Open Adobe Acrobat, click on 'Help' in the top menu bar, and select 'Check for Updates'.
If an update is available, follow the on-screen instructions to download and install it completely.
Click the Apple logo in the top-left corner of your screen, select 'Restart', and attempt to send the PDF again once the system reboots.

Verify and Reset the Default Mail Application
Reassigning the default email application can refresh the connection between macOS and Acrobat.

- 1. Open your PDF: Launch WPS Office and open the PDF document you wish to share.
- 2. Click the Share button: Navigate to the top right of the toolbar and click on the 'Share' icon.
- 3. Send via Email: Select the 'Email' option to automatically draft a new message in your default macOS mail app with the PDF perfectly attached.

Frequently Asked Questions
Why does Acrobat say it cannot create a mail document?
This error typically occurs when there is a miscommunication between Acrobat and your Mac's default email client, often caused by outdated software versions or misconfigured default application settings.
How do I manually attach a PDF if the in-app feature fails?
If Acrobat cannot create the mail document, simply save your PDF to your desktop, open your email application manually, create a new email, and use the 'Attach' (paperclip) button to add the file.
Does macOS Mojave have compatibility issues with Acrobat DC?
Certain older versions of Acrobat DC had known bugs with macOS Mojave regarding Apple Events and application permissions, which is why updating Acrobat to the latest version usually resolves the attachment error.
