Unable to open on macOS

You may get an error that blobsaver can't be opened.

The first time you open the application you will need to right-click (or control-click) the app, and macOS will show a prompt asking if you are sure you want to open the app. Accept the prompt, and from now on you will be able to open blobsaver like a normal app.

If this still doesn't work you can also manually remove the quarantine attribute on the app from the terminal:

xattr -cr /Applications/blobsaver.app
