Thanks Herb,

I overlooked this.

By the way, after transforming an Applescript that included all the my usual calls for a typesetting in TeXShop (saving, refreshpdf ,etc.) I could time it in the Terminal. Below are the results and the corresponding ones for straight pdftex calls (note all pdftexc alls included the synctex option):

(1) A 64p. document

(a) Applescript

real	0m1.163s
user	0m0.829s
sys	0m0.077s

(b) Straight pdftex

real	0m0.834s
user	0m0.777s
sys	0m0.040s

(2) 1 p. document

(a) Applescript

real	0m0.576s
user	0m0.347s
sys	0m0.065s

(b) Straight pdftex

real	0m0.344s
user	0m0.277s
sys	0m0.032s

Running the Applescript on the same file I couldn't detect a difference RAM vs. hard disk, though the results where actually written to the hard disk at least the tex file had been saved.


straight pdftex calls.

If I run pdflatex on a file without that option set no .synctex.gz file is created. It may be that TeXShop then resorts to a regular search which is not as accurate as one using synctex.
