Apple is not quite done tinkering with OS X 10.11.4 before its public release.

The company seeded the seventh beta of OS X 10.11.4 to developers this morning, a little over a week after Apple released the last beta for the desktop operating system.

Apple’s upcoming OS X 10.11.4 update will fix broken Twitter links in Safari. The fix is already available in the third 10.11.4 beta, which rolled out earlier this week, and it should be available to all by the end of March.

The third beta versions of iOS 9.3 and OS X 10.11.4 were made available to developers earlier this week, but it looks like Apple is opening up the new software updates to public testers as well.

Now you can try out the latest and greatest operating systems for Apple products, thanks to public betas for iOS 9.3 and OS X El Capitan 10.11.4. Both are now available for testing — even if you don’t have a developer account.

You can grab both updates from Apple’s beta program website for free. Take note, however, that this is trial software — and updating could cause some apps and features on your iOS or Mac devices to go funky or stop working altogether. Use these at your own risk.
