## Questions & Answers

**Q: Will this work with the Xbox One?**
A: I use this on my Xbox One and it works awesome.  It has a faster drive speed than the on board drive for the Xbox, so I get faster load times.  Not joking, I'm usually the first in the server on BF1, so I get a tank to start almost every game.

**Q: can I eat this?**
A: Sir/Ma'am,

You may eat this and anything else that you desire..

**Q: Is this product compatible with time machine**
A: You'll need a time machine if you want to buy this hard drive for a decent prize.  6 years ago I purchased this 4TB hard drive for $114.  Today, the exact same hard drive is on sale for $169.99.  So much for advancements in technology.

**Q: Does this work with Apple Time Machine after formatting it to Mac?**
A: I don't know that it does. When you go to the website you can select whether you need info related to either a PC or a Mac. My original answer related to Time Machine which is incorporated into the Mac OS.
