I have an iMac version 10.6.4. I received a newsletter link (pdf) via email that I tried to open and I was unable to read it. There was no text. A window popped up stating that I was unable to open the application Adobe Reader because it is not supported on this type of Mac. I called Mac and they said I needed to contact you to see about an updated version. When looking on your website it looks like you only have downloads up to version 10.6.3. What to do?
