Update Adobe Acrobat to the Latest Release
This specific form-field border rendering issue was a known software bug that Adobe resolved in a subsequent Acrobat DC update. Installing the latest patch is the official fix.
The glitch causing borderless text fields to default to a black border was isolated to earlier versions of Acrobat Pro DC running on macOS Mojave. Adobe released a fix for this in their October Acrobat DC update. By forcing the software to check for updates, you can patch the application and restore correct PDF rendering behavior.
Open Adobe Acrobat Pro DC on your Mac device.
Navigate to the top menu bar, click on 'Help', and select 'Check for Updates' from the dropdown menu.
If an update is available, follow the on-screen prompts to download and install the latest available release. Ensure the update completes successfully.
Once the update is installed, restart Acrobat. Reopen your affected PDF document and verify that the text field border and fill settings now display correctly without the black border.

Frequently Asked Questions
Why do my transparent PDF form fields suddenly have black borders?
This is caused by a known rendering bug in older versions of Adobe Acrobat Pro DC on macOS Mojave. The software fails to correctly read the 'transparent' property upon reopening, defaulting the border color to black.
Can I remove the black borders without updating Acrobat?
While updating is the only permanent fix, a temporary workaround is to change the field properties to a specific solid color that matches your document background, rather than leaving it set to 'transparent'.
Does this border color issue affect the printed version of the PDF?
Yes, typically if the black border appears on the screen due to this rendering bug, it will also show up when printing the document. Updating the software ensures both digital viewing and physical printing are accurate.
How do I make a PDF text field completely invisible?
In your PDF editor's form field properties panel, you need to set both the 'Border Color' and 'Fill Color' to 'Transparent' or 'No Color'. Ensure your software is fully updated to prevent these settings from being overridden.
