Hi all,
I'm using Isabelle for a lecture course on deontic logic (and other
topics) at the University of Luxembourg. Today, a student tried to
install Isabelle/HOL 2018 on her MacBook (macOS Sierra, version 10.12.5,
MacBook Air) and, while doing so, it showed an error message saying that
it will not run Isabelle since it's untrusted (or so). See the exact
message as screenshot attached to this e-mail.
I'm sure there are options to disable this check (as a hot fix), so it's
not an urgent problem. But maybe it would be a good idea to look into
this in the future; it would be sad to see people not using Isabelle
just because of this. Of course, I don't know if this can be addressed
by Isabelle developers at all. Does anyone have experience with this?
Thanks in advance!
Best
Alex

It's very simple. Right-click on the Isabelle application and choose "Open". You will now get a dialog box asking whether you want to run the application even though it is untrusted. Click that you will. From now on Isabelle can be started the usual way by double-clicking the application.

See this note on http://isabelle.in.tum.de/installation.html
"""
The Isabelle application lacks special certificates and signatures, so
Apple tends to reject it by default. Running it for the first time might
require a right-click or control-click on the application icon to open
it explicitly.
"""
Some years ago Apple (and MicroSoft) have made it very difficult to run
arbitrary applications: one needs to pay a subscription fee for
developer status and then submit the application to an "app store".
