[OS X TeX] New MacOS 27 causes TeXShop 5.57 pdf page jumps on typeset activation

[Brian Coleman]

Hi Juan,
I downloaded https://pages.uoregon.edu/koch/TeXShop-5.58-GG.zip
and it works fine on McOS27. No pdf jumping as before on 5.57.

Strangely clicking opened 5.58 version's  'About TeXShop' returns `Version
5.57'.

Many thanks to all.
