App reported as damaged and won't run

[machawk1]

Consistent between homebrew and DMG'd .App installation. 594 has the trace on some intermittent issue with homebrew. WAIL 0.2025.03.03. Apple M3.

Try doing
xattr -l /path/to/application.app
You'll probably find com.apple.quarantine listed. If so, you can get rid of it with
xattr -dr com.apple.quarantine /path/to/application.app
You might want to kill the other attributes it returns, as well.

Related, we might need to sign the app (see #183 and #530)

Aside: worked on getting Apple Dev creds for my org but the reset is sent to a Mac not in my immediate possession (i.e., not the MBP M3), so will need to circle back. That auth might only permit iOS development, so perhaps it's moot.

Running the following fixed it for me:
sudo xattr -dr com.apple.quarantine /Applications/ASCII\ Studio.app

% xattr -l /Applications/WAIL.app
com.apple.provenance: 
com.apple.quarantine: 0181;67c9f804;Homebrew\x20Cask;72C1A7D3-F46B-4F1C-B9EC-6ED825CC5D4D

https://github.com/orgs/Homebrew/discussions/3348 describes the ``--no-quarantine'' flag that can be used so that macOS does not report the app as "damaged".
