Answer by ron.bannon for Hi,I am new to MAC and all the related stuff. Changed from MS Winxxx to Mac because they said it would be much user friendly. But now I have some problems. I am using Texshop. I tried to run Sagetex, but it does not work. I get the message "Latex error! File sagetex.sty not found". I copied the folder sagetex everywhere in my system. I cannot definitely say, where the latex installation folder is. Or how to get to the installation folder. I spent hours and hours following the advices I found on the web. Without success. I am using Lion with its latest update. Texshop has also its latest update. Same to Sage. When I run the example.tex from Sagetex folder, everything is fine. But when I run Example.tex from a folder located e.g. on my desktop then the error message appears. I know that the system cannot find the sagetex.sty. But why? I followed the instructions given under: http://www.sagemath.org/doc/installat...Any hint appreciated. Keep on rocking'Rick

Open this folder `~/Library/TeXShop/Engines/Inactive/Sage/` and follow the instructions in `About Sage.pdf` and all should work fine. Make sure you have the Sage.app version installed. For $TeX$Shop users needing more assistance, I have written a ~50 page [guide](http://devio.us/~bannon/sage/) that should help.
