# TeXShop gives “(null) does not exist” error when compiling postscript [closed]

Mac: 10.7.3

TeXShop version: 2.47

When I try to compile .tex into a Post Script file, TeXShop gives me an error as follows:

(null) does not exist. Perhaps TeXLive was not installed or was removed during a system upgrade. If so, go to the TeXShop web site and follow the instructions to (re)install TeXLive. Another possibility is that a tool path is incorrectly configured in TeXShop preferences. This can happen if you are using the fink teTeX distribution.

I can compile PDFs fine though. I don't remember updating TeXShop recently, so have no idea what's going on. Though I almost never compile to PS, so not sure if this problem is new either. Found a post suggesting I delete the preference file, but that doesn't work. If not a solution to this problem, does anybody know which script it is looking for and how to run it from command line?

Open the TeXShop preferences and click on the Engine tab, and then in the part that says "TeX + dvips + distiller" click on the two default buttons (one for TeX and one for LaTeX). Then try again. Do you still get the error? – Alan Munn Nov 16 '12 at 19:42
@Lena Please let us know what Alan's suggestion reveals. If there is no more info then the question is likely to be closed. – Joseph Wright Nov 19 '12 at 8:46
