I have merely pushed two changesets:

>>  (4) http://isabelle.in.tum.de/repos/isabelle/rev/6d9c43f51e60 (today)
>>  (5) http://isabelle.in.tum.de/repos/isabelle/rev/4ad6182d5bb9 (today)

For extra convenience I have added the full URL and some hint about the 
dates.  The full information is already given by the changeset ids 
(abbreviated SHA1 keys), so with the Mercurial front-end of your choice 
you can retrieve all these details, and more.

The above merely gives you the updated Admin/MacOS/App1/README and mk 
script to repeat the process yourself.

Here are your edits after according to diff -w:

The Info.plist edited here was generated by Platypus 4.0.  The main thing 
is the executable application wrapper of Platypus, and the plist needs to 
correspond to that.  After updating to Platypus 4.7 I've got a different 
Info.plist, which was not very surprising.

Editing generated files only works one-shot, not for long-term 
maintenance.

Do you have some concrete links with explanations how this works?

Our situation is not quite classic:

Where "nested" means that the shell script invokes another application, 
which was some Emacs.app in 2009 when I disabled the attempt with the 
document--application connection at that time, see again 
Isabelle/9343d4b7c5bf with the Mercurial changeset browser of your choice.

BTW, since you are now one of the Proof General maintainers, you may have 
to understand its integration with Isabelle.app, and potentially find ways 
to avoid some of its oddities caused by Isabelle.app invoking Emacs.app 
via a shell script.

For Isabelle/jEdit there might be ways in the future to avoid all that, 
running more directly some .jar application.  But that reform is not 
imminent.
