Beta 4 of iOS 10.2.1 and MacOS Sierra 10.12.3 Released for Testing

MacOS Beta and iOS Beta

Apple has released the fourth beta versions of iOS 10.2.1 and macOS Sierra 10.12.3 to users participating in the beta testing programs.

The updated beta builds can be downloaded now from the software update mechanism of iOS or Mac OS for any device or hardware enrolled in the developer beta or public beta testing programs.

No new features are known or expected in either iOS 10.2.1 or macOS Sierra 10.12.3, suggesting the small point releases will focus primarily on bug fixes.

Considering that beta 3 of the same system software versions was released just a few short days before beta 4, it’s possible that the final version of each release will be unveiled to the general public soon as final builds.

    I’d like to see Finder and Quicklook fixes.

    With Quicklook, if you move the selection with the arrow keys, the picture isn’t always updated.

    If you rename a file or move it into a folder, most often the folder doesn’t automatically sort everything. (CMD-J, sort it another way, then sort it the way it should been.)

    Selecting items with the shift+arrow doesn’t work as it should

    Sometimes the arrow key gets stuck and won’t move.

    Yes, I reinstalled it twice.

    There are others. We don’t need a new OS every year. We don’t need a UI that looks like an extraterrestrial circus poster. We need an OS that works.

    Users who edited certain PDF files with the Preview app in macOS 10.12.2 experienced corruption of PDF files. In addition, PDF files created with Zipforms (used by most Realtors) were corrupted. At least 3 users who tested beta 3 of mac OS10.12.3 reported that these PDF-related bugs were fixed.

    Imminent release of a new version of macOS is welcome news. Corruption of important business-related and personal data files is a serious issue. It is a shame that Apple released macOS 12.x with such serious bugs, and even more unfortunate that it has taken so long to correct.

      There is no mention of fixing PDF editing in 10.12.3, suggesting that Apple has not fixed it.

      I am not sure they care. People are saying Apple has abandoned the Mac and does not care. No wonder half my office is installing Windows 10!

    Pretty sure 10.2.3 was out years ago. Looking forward to 10.12.3 though… ;-)
