>>> Are you sure you even want to look at the result of the first typeset after a removal of aux files? The first typeset has no cross-references, no table of contents, etc. Often the page layout changes substantially between the first and second typeset. This may be the reason why you think you look at an "incorrect" page. IMHO the only reasonable "workaround" is to hit Cmd-T immediately a second time. Or use one of those scripts that do this automatically for you.

Download Quick `Start Guide for latexmk with' for a quick introduction (it also points you to the full documentation).

I'm not sure what you mean about the necessity of removing the .aux files. Latexmk will check to see if something has changed (e.g., a change in the source file) and rerun what is necessary.

Any problems with your .aux files when there is an error means something about what is going on when the error occurs is causing the problem.

Also, remember that there is much more going on that just a single compile when using the latexmk engines. If you had to do all of that manually it would take much longer.

Good Luck,
