Capella : macOS

Hi all

Does anyone run Capella in MacOs? Is this trivial or any specific problems reported? I am evaluating a change of platform. Any feedback is welcomed.

many thanks,

Hi Ricardo,

Yes, there are quite a few Capella users on macOS, including on Apple Silicon (M1/M2), and several threads on this forum come from them. The problems reported are mostly minor and not specific to Capella itself:

  • “App is damaged and should be moved to the trash” at first launch (reported for Capella 5.0 and again for 7.0 on an M2 with macOS Sequoia). This comes from macOS Gatekeeper putting the downloaded archive in quarantine, because the application is not signed. It is fixed once by removing the quarantine attribute: xattr -d com.apple.quarantine /path/to/Capella.app
  • Copy/paste not working in the rich-text Description panel (reported with Capella 6.1 on an M2). This panel embeds a native browser component, so its behavior differs between Windows, Linux and macOS. A workaround is to disable the rich-text description editor in capella.ini.
  • Older reports (Capella 1.x to 5.x) were mostly about Java versions, which should no longer be a concern as the JRE is now bundled.

Once these are sorted out, Capella behaves like on the other platforms, since it is the same Eclipse-based product.

Good news for the first point: in the version to be released at the end of this month, the macOS application will be properly signed, so the quarantine workaround will no longer be needed. The splash screen will also be correctly sized on macOS.
