I am getting this error when trying to execute an unsigned application that was downloaded via the native web-browser; Safari.app.

LSOpenURLsWithRole() failed with error -10810..

There used to be a solution to a similar question on AskDifferent that utilised the CLI to strip certain attributes from the file in question, allowing it to run. It was a good solution but it has since been deleted and now I've forgotten what it was.

Does anybody know the command('s?) that I'm referring to?

  • Could you show your research? When you say "there used to be a solution" that doesn't show what you did now to research your problem. See apple.stackexchange.com/help/how-to-ask on how to ask a good question per the site's guidelines. – bmike Oct 1 '15 at 14:25

I believe it's xattr -rc app-name, but I could be completely wrong.

  • I think you might be on the right track.. I recall there being more to it though.. – voices Sep 22 '15 at 6:35
