How do I set Preview as default to open PDFs

Note: These instructions apply only for PDFs opened through Google Drive. For the Read&Write for Google Chrome PDF Reader to not open PDFs from external links you would need to untick Use by default for the Texthelp PDF Reader extension as shown below.

To have PDFs to open in Preview instead of the Read&Write for Google Chrome PDF Reader, go to Google Drive and click the Settings button

Click Done

Note: Read&Write for Google Chrome can still be used with this option selected

PDFs will now open with Preview by default. PDFs can then be opened with the PDF Reader by using the Open with option in Preview
