It won’t be long now before everyone begins upgrading to iOS 8, but there’s one feature of the new software that you shouldn’t activate quite yet. iCloud Drive, Apple’s answer to Google Drive, Dropbox and OneDrive, is part of Continuity — a new set of features which will allow iOS and Mac to integrate with one another more deeply than ever before. We called Continuity one of the best new features on iOS 8, but before you dive into iCloud Drive, you should know that it will only be compatible with OS X Yosemite.
This doesn’t just mean that you won’t be able to transfer files from your phone to your computer either; some of your apps won’t sync up at all until OS X Yosemite is officially released. Nik Fletcher of Realmac Software, the company behind popular productivity app Clear, has taken to the company’s website to help users choose the right iCloud Drive option when upgrading.
If you upgrade to iCloud Drive, you will only be able to sync with devices running iOS 8 or OS X Yosemite. As OS X Yosemite is still pre-release (and not yet available) upgrading to iCloud Drive will prevent you from syncing with Clear for Mac until both OS X Yosemite is released and you upgrade to OS X Yosemite.
Worst of all, developers won’t be able to work around your decision if you opt in to iCloud Drive, so you’ll be stuck until Apple releases OS X Yosemite. Here’s a handy screenshot of what the menu will look like and which option you should choose:
