# [OS X TeX] very slow pdflatexmk runs after upgrade TeXShop to 3.80

Compilation, with the pdflatexmk engine, is now proceeding quite snappily, as I had become accustomed to seeing, after I did the following:

(1) deleted TeXShop.app, ~/Library/TeXShop, and ~/Library/Preferences/TeXShop.plist (after backing up both the latter two);

(2) installed TeXShop 3.80, then updated it to 3.81;

(3) recustomized the TeXShop preferences — some directly through the TeXShop > Preferences dialogs and others by modifying ~/Library/Preferences/TeXShop.plist directly in an editor or by using at least one shell script to do some “defaults write” commands (there were some apparently obsolete preferences in my old TeXShop.plist that had accreted over the years and that I did not restore to the new version, without apparent misbehavior); and

(4) zapped all auxiliary file for my book-length document;
in its root document commented out the entire \includepnly block;
ran pdflatexmk on the whole thing;
restored the \includeonly block; and
am careful now _not_ to delete auxiliary files unless something goes very wrong and I”m forced to do so.
