Apple has released the fourth OS X 10.11.4 preview for registered developers to test ahead of its expected release next month. The software update to the Mac will likely be released around next month’s March 15th event and is expected to coincide with a new version of iTunes. For Mac users, the latest version of OS X El Capitan adds enhancements like being able to view and share Live Photos originally taken on the iPhone 6s or 6s Plus as well as the ability to lock notes behind a secure password. We’re check out the latest beta and update with any changes.

Notes on the Mac also gains the ability to import data from competing note-taking apps like Evernote (here’s a tutorial) or just plain text or rich text files.

Both the Photos and iBooks apps have also been focus areas for the software update, and issues loading Twitter URLs with Safari appear to be resolved as well.

Let us know in the comments, via email at tips at 9to5mac dot com, or on Twitter @9to5Mac if you spot any changes in the new beta, and we’ll update with changes we find as well.
