Verification

• I understand that if I ignore these instructions, my issue may be closed without review.
• I have retried my command with --force.
• I ran brew update-reset && brew update and retried my command.
• I ran brew doctor, fixed as many issues as possible and retried my command.
• I have checked the instructions for reporting bugs.
• I made doubly sure this is not a checksum does not match error.

Description of issue

The current text printed is:

    The Apple Silicon (arm) version of mark-text is not signed, and
    will display an error stating it is damaged and can't be opened.

See:
https://github.com/Homebrew/homebrew-cask/blob/master/Casks/m/mark-text.rb#L25

Install on arm is discussed in this mark-text issue:
marktext/marktext#2983

And executing:

xattr -cr /Applications/MarkText.app

Appears to resolve the issue, but it isn't mentioned during the install.

Could we have either the solution or at least a link to the issue printed during install so users know what to do?

My suggestion:

    The Apple Silicon (arm) version of #{token} is not signed.  You may need to
    execute 'xattr -cr /Applications/MarkText.app' prior to running this on arm, see:
    https://github.com/marktext/marktext/issues/2983

Command that failed

brew install --cask mark-text

Output of command with --verbose --debug

==> Caveats
The Apple Silicon (arm) version of mark-text is not signed, and
will display an error stating it is damaged and can't be opened.

etc...

We will not recommend people to remove security features. The correct fix is for the user to file an issue with mark-text so they start correctly signing their software.

[keeely]

If you don't want a recommendation to remove a security feature simply remove that part, in other words:

    The Apple Silicon (arm) version of #{token} is not signed.  See:
    https://github.com/marktext/marktext/issues/2983 for details.

Then the user can decide what to do (including complain or fund the signing if they want to).

I'll happily review a pull request to that extend

@SMillerDev, I made a PR for it: https://github.com/Homebrew/homebrew-cask/pull/160508/files
