Well the device is the issue with Hippa compliance it the security. Which means it needs network security and firewalls, encryption and virus protection. Here is a paragraph for a article about Hippa compliance. I sure this person is talking iOS (ipads) and not MAC OS X.
There are a few neat resources which you can freely leverage in your own attempt to get up to par with what HIPAA entails. For starters, the United States Department of Health and Human Services provides this excellent collection of starter guides and outlines on operational best practices. You can also choose to use the free HIPAA Security Rule Toolkit which is distributed by the National Institute of Standards, and works on Windows, Mac OS X, and Linux systems in providing clear instructional assistance on compliance. HITECHAnswers.net also has a great collection of introductory readings on what covered entities are, baseline definitions of HIPAA regulations, and much more.
