Cannot open nightly from 2024-10-07 on MacOS Sequoia (15)

[barmac]

Describe the bug

I just downloaded the latest nightly, and MacOS refuses to open it:

This may be related to my recent upgrade to MacOS Sequoia, but also to https://github.com/camunda/camunda-modeler/pull/4579

I can open v5.28.0 though so it's less likely that this is solely due to MacOS upgrade.

Steps to reproduce

1. Download nightly from https://downloads.camunda.cloud/release/camunda-modeler/nightly/
2. Try to open
3. now this happens

Expected behavior

Nightly opens without problem.

Environment

• OS: MacOS 15.0.1
• Camunda Modeler Version: nightly
• Execution Platform: [e.g. Camunda 7, Camunda 8]
• Installed plug-ins: [...]

Additional context

No response

I am moving this to the ready as this may block the next release.

Maybe it's due to missing notarization?

• skipped macOS notarization reason=notarize options were unable to be generated https://github.com/camunda/camunda-modeler/actions/runs/11221353989/job/31191526949#step:7:219

I think this goes in line with https://github.com/camunda/camunda-modeler/issues/4578. We do not use the built-in notarization, but our custom one.

This should print a message:

  • notarizing app from path: ${appPath}

It instead prints a skip message.

To date we simply don't notarize nightly builds. We could start doing that.
