This is a patch that prevents a run-time exception when mounting an image fails when a .dmg file is generated.

Hi @jyoo980! Great!!! It seems I've not been using well "optionals" 😅 Thanks for your contribution

Hi @fvarrui!

The Optional class is really annoying to use; and there are a lot of gotchas that can be difficult to catch. If you're interested in automated tools to help you catch bugs like these or more, I've been using the Checker Framework, which helps find bugs like these at compile-time!
