Unable to open on new mac

Ricky Blaha July 14, 2020

I get this error when trying to open on a new mac:

 

"“Sourcetree.app” can’t be opened because Apple cannot check it for malicious software.

This software needs to be updated. Contact the developer for more information.

Chrome downloaded this file today at 2:31 PM from www.sourcetreeapp.com."

Another way to do this is to open your application tray by right clicking on it and choosing "open application" This will open the applications folder in finder.

You can then right click on Sourcetree and choose open. This will then give you the option to open the application and MacOS will remember your selection and allow you to open the application the normal way next time.

Hi Ricky, welcome to the Community!

The MacOS feature that prevents applications from being opened sometimes is called Gatekeeper. You can create an exception for the Sourcetree app by following these steps:

In macOS Catalina and macOS Mojave, when an app fails to install because it hasn’t been notarized or is from an unidentified developer, it will appear in System Preferences > Security & Privacy, under the General tab. Click Open Anyway to confirm your intent to open or install the app.

The warning prompt reappears, and you can click Open.

Cheers,
Daniel
