Apple today seeded the sixth beta of an upcoming OS X 10.11.4 update to developers and public beta testers for testing purposes, less than a week after seeding the fifth OS X 10.11.4 beta and more than a month after releasing OS X 10.11.3. OS X 10.11.4 has been in testing since January 11.

The sixth OS X 10.11.4 beta, build 15E61b, can be downloaded through the Apple Developer Center or via the Software Update Mechanism in the Mac App Store.

OS X 10.11.4 offers a couple of new features, such as Live Photos support in Messages, the ability to password protect notes in the Notes app, and an option to import notes from Evernote, but like the recent OS X 10.11.3 update, it appears to focus primarily on under-the-hood bug fixes and performance improvements. Almost all of Apple's OS X updates to date have been smaller updates that improve performance rather than introduce new features.

We'll update this post with any features or significant changes that are discovered in the sixth beta of OS X 10.11.4. OS X 10.11.4 is likely to see a spring release alongside iOS 9.3, tvOS 9.2, and watchOS 2.2, with the new software coming as early as March 21, the date of Apple's planned spring event.

Let's see how this one pans out..over the last couple of betas only I couldn't help but report a few dozen very irritating hardcore long-standing bugs only to get responses from 'Engineering' that these are duplicates of others, still open ones...Funny thing is that MOST of the already open ones have IDs that pertain to OSX versions way before Yosemite... :confused:

May be time to change the site name to "iosrumors" or "applerumors".

Why are this and the WatchOS posts delegated to the blogs whilst the iOS update gets the front page?

Probably the fact that there are BILLIONS of iOS users and MILLIONS of WatchOS users with even fewer Mac OS X users... I'm sure some clever cookie can come up with some actual numbers.

Just a thought.
Eh, I prefer Macintosh news over iOS news, tbh... I'm both a Mac and iPhone user, but Mac news are generally more exciting. I sure wish we could see more heritage to the classic Macintosh name, as well.

I only submit feedback via the Feedback forms, Crash Reporter, and occasionally, the Feedback Assistant. I never see anything after that. There's some LONG-standing issues with OS X that seem to be completely ignored by Apple. I know maintaining four platforms is a big task, but surely they can invest a bit more time in refining some of the smaller items? Focus seems to be on moving forward to the next great thing rather than improving the "now".

Apple Sheds More Light on iOS 17.5 Bug That Resurfaced Deleted Photos

Friday May 24, 2024 2:36 am PDT by
Last week, some iPhone users reported that Apple's iOS 17.5 update had introduced a bug that caused old photos that were deleted to reappear in the Photos app. Apple quickly released an iOS 17.5.1 update to fix the issue, but for many users, its explanation of "database corruption" in the release notes was all too brief, and did little to allay concerns about the privacy of their data.
