Dear Lyx Experts, Thanks very much in advance for your help.
I recently updated Lyx only to find out that I should have updated MacTex first. I downloaded the latest MacTex and then found that the Preview Button was greyed out. From the Lyx Users Archive, I found out how to access in the Preferences, File Handling > File Formats; I selected Latex (pdflatex) in the Format drop down box and then found that the option of pdflatex was not available in either of the drop down boxes for 'With TeX Fonts' and 'With non-tex Fonts'. I saved this page with the result that the Preview button became operable, but when I click on it, all I get is a tab in Safari with MathHTML, and not the beautiful PDF output that you usually get opened up in Preview miraculously before your eyes, as has happened so many times before. Would greatly appreciate your assistance, as you do need the beautiful Preview output to send to the publishers. Best wishes, David Forrester (ANU Ph.D. Alumnus)
