IMPORTANT:
- Due to a recent security vulnerability in Adobe Acrobat Pro and Reader, it is critical that you perform an update to receive the most current security patch. For details, see our Adobe Acrobat and Reader Security Update page.

- Safari users who have set Adobe to display PDFs in their browsers have reported difficulty downloading PDF syllabuses from courses.brown. See the "Special Instructions" section below for the solution.

Adobe Acrobat Reader is a free program available for download from Adobe.

Adobe Acrobat Reader (vendor: Adobe Systems Inc.) is used to view and print Adobe Portable Document Format (PDF) files.

1. Download the Adobe Acrobat Reader from the link to Adobe below.
2. Follow the on-screen instructions to complete the installation.

Safari users who have set Adobe to display PDFs in their browsers may have difficulty downloading PDF syllabuses from courses.brown. This appears to be a security issue between Adobe and Web-Auth. Set your Safari browser to use Preview when downloading PDFs rather than Adobe. To make this change:

1. Open Adobe Reader (located in your Applications folder) and select "Preferences" from the "Adobe Reader" menu.
2. Choose Internet from the left menu.
3. Make sure that the option "Display PDF in browser using:" is NOT checked.
