[OS X TeX] TeXShop crash problem

[Nestor Aguilera]

Hi:

It might be the case that the program solving the ode doesn't release memory after finishing and the operating system is using secondary memory (perhaps a hard disk?). 

Perhaps with a modern computer and newer macOS this doesn't happen, but I would suggest that you look in Activity Monitor how much memory is used 1) after compiling and the pdf is produced and 2) after quitting TeXShop and opening it again but before compilation. 

Best,

Nestor

This may be at the root of my problem: in any case, the compiling of a pdf from the source takes considerably more time than a paper of 50 pages normally would—time comparable to what it used to take to typeset my 500-page book.  Also, during the process of compiling, the process occasionally pauses, and only contnues (but with no error messages) if I go to the console and hit return.

This (always) happens if I go to the toolbar at the top and type in a page number other than the one currently displayed and then hit return;  it (always) happens if I use the command-f search function.  Sometimes it occurs in an apparently spontaneous way.  It wasn’t happening when I started writing up the notes, only after they reached a certain length.  But since then, it was completely predictable that it would happen.  I would have to force quit TeXShop.  When I did so and returned to TeXShop, then so long as I didn’t typeset again, these functions seemed to work fine.
