US Play not executable on MacOS Catalina

[bnest]

Issue type: Bug report

Actual behaviour

When downloaded the latest release https://github.com/UltraStar-Deluxe/Play/releases/tag/v0.3.1 and using the MacOS binary, it is not usable on MacOS 10.15.7 (19H524).

When double clicking it says: "UltraStar Play can't be opened". When using the terminal with "open UltraStar\ Play.app" it quits with error:

LSOpenURLsWithRole() failed with error -10810 for the file /Users/MyUser/Downloads/StandaloneOSX/UltraStar Play.app.

Expected behaviour

The binary should start US Play

Steps to reproduce

Should be the same on all MacOS Catalina installs

1. Download v0.3.1
2. Start binary

Details

The problem can be resolved / I resolved it.

This issue seems to be somehow related to the MacOS guard functionality for unknown binaries.
Using:

chmod +x UltraStar\ Play.app && chmod +x UltraStar\ Play.app/Contents/MacOS/UltraStar\ Play 
xattr -dr com.apple.quarantine UltraStar\ Play.app

Resolved the issue.
Maybe including the executable permissions for macOS building process could already solve half the problem.
Unsure how to prevent the attribute flag :-/

We should add installation instructions with this workaround in the wiki.

I've added the workaround to the new installation instructions wiki page.

Re-open. Maybe we find a way to prevent this issue

this should be rather easy to fix: have travis set the +x attribute before uploading the file to aws, and when pushing a new release, set the required attribute on the file in a linux/mac environment before uploading the file?

[achimmihca]

This needs re-testing once the MacOS build using the unity-builder GitHub Action is working (see game-ci/unity-builder#295 ) .
Could be that they don't have this issue in the first place.

Still happening on macOS Big Sur after adding +x permission:

OUTDATED check wiki instructions
