[texshop] Very strange bug while using TeXShop

[Bruno Voisin]

A very strange bug just appeared while using TeXShop. This is with the latest TeXShop (5.03) and beta macOS (13.1 Beta 2). I don't know whether this beta macOS is the reason for the bug.

Here's the thing: I opened TeXShop, went to File > New to open a new window, pasted inside the TeX code I was willing to Typeset, then went to File > Save to save this to a file.

The problem is, nothing happens then: no file saving dialog, nothing. I tried pressing the Alt key to be offered Save As: same result. The window keeps it Untitled name, close to it there's "Edited" next to a small downward-facing chevron which doesn't present any contextual menu though. Doing a Cmd-Click on the window name, no pull-down menu appears showing the path to the file on the disk.

Even pressing the Typeset button does nothing. And going to File > Close does not close the window.

It's as if TeXShop is in this sort of limbo where nothing can happen.

I restarted my Mac several times, the situation remains the same. I thought, maybe iCloud Drive activated itself even though my Mac is set not to save Documents and Desktop there. But there's no trace of a TeXShop document on iCloud Drive.

The only thing that works is deleting the files in ~/Library/Saved Application State/TeXShop.savedState. This suppresses the window that refuses to be closed. But the next time I try to open a new document in TeXShop, the same problems arises.

I've no clue what may be happening. I'll try booting in Recovery mode and apply Disk First Aid to my drive, just to be sure the problem isn't there. And if that doesn't change things, erase all TeXShop prefs and related files I can find in ~/Library, see what happens.
