If you’re interested in Mac Security, the next edition of my Enterprise Mac Security book is now shipping. You can get it here http://www.amazon.com/Enterprise-Mac-Security-OS/dp/148421711X. The book is shipping from 3rd party sellers, but should ship directly from Amazon soon at the regular price. I don’t usually know exactly when, but it should also appear for Kindle and on the Apple Books store as well. Hope you enjoy!
