Resources folder on mac, and the good old days

[Brian Milby]

Once I took a version of the LC IDE and edited one of the files in the package before opening it the first time.  It would not open and complained about being corrupt/modified/something (can’t recall exact message).

I trashed it and extracted a fresh copy.  I launched it once and then quit.  Then I modified the file (actually a widget I believe).  LC opened fine this time.  So, at least a version or two ago (pre Catalina), the package contents were only verified as unchanged on first launch.

The correct place for application support files is the Library/Applications Support folder, and this has been the AppleGuideline for a very long time (although I am not quite so sure about that *always* being the case..) I was wrong, naughty, and I promise… Mea culpa, mea maxima culpa. I strongly advise against this awful filthy and degrading practice.

With one big caveat: this is ad hoc software, distributed to a small group of users (Colin: by all the usual methods - server, email, DropBox… they all work to deliver a working app without my having to renew my lapsed Apple Developer registration.) If I were to commercialise the app and so notarise it, I would expect writing to the Resources folder *not* to work, probably notarising keeps a checksum of the whole app bundle not just the executable. Maybe this distinction between ad hoc and notarised software is part of the confusion of this very confused thread, to which I have regrettably added more confusion.

Explaining how to access the Library is only slightly more arcane, but I really don’t want the uninitiated venturing into that dark scary and very dangerous place .

Surely best to refer to the definitive source, the Apple Support documents which you can get by googling “How to open an unsafe app in Big Sur” (or Catalina, or Mojave). The instructions from Apple are clear and straightforward, unlike some tech forums which start off by talking about using the terminal to turn off Gatekeeper.
