Can I play an All-Region DVD on my MacBook Pro?

Hello!

I have a MacBook Pro (13-inch, mid-2012) and I am considering buying a DVD. However, the DVD is "All Regions" (it's from Germany) and I have previously only played Region 1 DVDs on my MacBook (as I live in the United States). Before I buy this $50 DVD, I want to make sure that I can actually play it on my MacBook without messing anything up; I want to be able to still watch my other Region 1 DVDs after watching this All Regions DVD.

Please let me know if you need any additional information.

Thank you!
