How to get "evaluate" to provide an output on OSX 10.7
Just getting started with Sage and so far I am quite impressed; unfortunately I have so far been unable to get the Sage notebook to run properly on OSX 10.7 (Lion). I did manage to get Sage to run successfully on Linux following a similar install procedure, so hopefully I am not completely off-track.
I have downloaded sage-5.2-OSX-64bit-10.6-x86_64-Darwin.dmg and unpacked into a user-owned directory. Furthermore, based on the FAQ entry "I am using Mac OS X. Where do I put the jsMath ..." I have downloaded TeX-fonts-10.zip and TeX-fonts.zip (did not know which one was needed), and unpacked the .ttf files into /Library/Fonts/ .
After executing ./sage from the install directory, I am able to execute commands from the Sage command line in the terminal window with the expected resulting outputs. However, when I execute notebook() and try to evaluate the same commands in a worksheet in the browser, then "evaluate" provides no output, regardless what I use as inputs. I have the same result with Firefox, Chrome, and Safari, and (un)ticking "Typeset" also does not generate any output.
Any ideas?
Once you open up a worksheet in your web browser, try a hard refresh of the screen. (E.g., with Safari, hold down the option key while clicking the little "refresh" icon in the address bar.)
Unfortunately I get the same result after refresh/reload. There is a thin red line to the left of cell box and cell output area. Cell output area after "evaluate" only shows a thick green vertical line, and when hovering over that line the mouse pointer shows a "busy" animation (e.g. rotating blue wheel in Safari)
