[OS X TeX] [OT] Présentation quitting immediately when launched

[Luís Sequeira]

Hi

Apologies for the slightlyt off topic message.

I have used Renaud Blanch's great "Présentation" program (not to be confused with Apple's Preview, which might be called that way in the French localization) to display my beamer created slides in my work as a teacher.

This has worked great, as it provides a presenter screen and several other nice features, like notes, the ability to annotate or drawn o the slides, a web view, and more.

Fairly recently the application closes immediately upon launch. The Dock icon appears and goes away, and the Console indicates that the app existed after a few milliseconds.

The problem occurs in Safe Mode as well, but it does not occur on a different mac, even though they are both running the same macOS 26. Reinstalling does not help. 

Any suggestions will be greatly appreciated.

pS: here is part of the contents of Console log, if it helps:
