Yosemite

iCloud Drive brings new functionality to iCloud for those running iOS 8 and OS X Yosemite. Even Windows 7 and later can join in the fun via iCloud for Windows 4.0. While iCloud Drive adds the ability to use Apple's massive data centers for general storage, there are limitations when using iOS 8.

Handoff is a highly touted new feature of iOS 8 and OS X Yosemite that allows for seamless continuity between your devices. For example, if you start an email on your iPad, Handoff will allow you to pass the draft to your iMac and continue writing it there. Handoff will also work with Safari, Notes, Keynote, Numbers, Contacts, Calendar, Pages, Messages and Reminders, and it is open to developers as well, so it will soon work with third party apps.

If you've been having trouble setting up Handoff, you aren't alone; there has been a lot of confusion about it over the past several days. Here are a few potential reasons for your frustration:
