# using sage engine during compilation of tex file

I would like to automate calling sage after compiling a tex file in TeXShop. I have copied the `sage.engine`

file from `~/Library/TeXShop/Engines/Inactive/Sage`

to `~/Library/TeXShop/Engines/`

and followed the instructions in `About Sage.pdf`

.

I've included the line `% !TEX TS-program = sage`

in my tex file, but when I compile the file the sage expressions don't compute. I only get `??`

for sage expressions. If I run sage on the sagetex.sage file and re-compile the tex file, then everything looks good.

I'm running TeXShop 3.75 on MacOS 10.10.5
