5 Reasons Not to Install OS X El Capitan and 7 Reasons You Should

Install if You Use iOS 9 or iOS 9.3

Do you own an iPhone or iPad that is running iOS 9 or iOS 9.3? If so you should probably put this upgrade on your Notes to do list on your phone and make it happen.

While there is not as many iOS to OS X connectivity features as we saw with last year's upgrade your Mac needs to be on OS X El Capitan to use the new Notes features that include to do lists, adding attachments, links and more. Until you upgrade your notes from iOS 9 will not sync to your Mac. You'll need the OS X 10.11.4 update to unlock notes you lock on iOS 9.3. This new version of OS X will also let you look at Live Photos on your Mac. 

AirDrop and Handoff are also now more reliable on OS X 10.11.3, allowing users to answer calls on the Mac and quickly send files without failures. 

In short if you want to use all the new iPhone and iPad features, you need to stay up to date with OS X updates. Of course you should also install the latest iOS 9.3.2 update to keep your iPhone up to date as well.
