Apple Seeds Fifth macOS Sierra 10.12.1 Beta to Developers and Public Beta Testers

macOS Sierra 10.12.1 appears to focus on bug fixes and under-the-hood performance improvements to address issues that have been found since the operating system's release, and it's also likely adding features designed for next-generation MacBook Pro models ('https://www.macrumors.com/2016/09/28/late-october-macbook-pro/') set to be released later this year.

Don't even give them the option. Change that to next week.

For the love of god please fix the issue with external 4K monitors (Dell P2415Q in my case) not turning on when connected to a closed rMBP on a restart and then not allowing the built in screen to turn on when opening it, causing a hard reboot with the screen open. Worked great in all versions of El Capitan..

Absolutely agree. Asus here, same problem.
And not just that:

* flickering screen,
* buggy video controls,
* sudden resets,
* BEACHBALLS,
* software that stopped for working (for no apparent reason),
* slow behaviour,
* iTunes before that was way snappier (don't get me started on the stupid hearts-system where one state cannot be accessed in playlists).
* iTunes Backups from iPhone cannot be saved "no disk space" (with 230GB available),
* Word cannot save temporary files anymore - and crashes,
* Bluetooth automatically disconnects - reconnects - disconnects.
* Cannot use the Apple Watch to unlock, as I have several iPads, including an old one which will stop working once I activate two-way authentification...
* losing WiFi
* Safari cannot open webpages (Firefox can)
* Lightroom crashes when converting to DNG


... all of this worked with Mavericks and stopped with Sierra. Thank you, Apple.

The list is so long, I have regretted updating my system and I will certainly never ever again update my computer, once the last service update has come along.
Sierra has been a disappointment all along.

Phew...

Has Apple forgotten that people actually work with this OS and depend on its reliability. Have they forgotten that this was the reason we chose to invest money?

I love Apple. I hate what it has become.

I hope they've fixed all the Safari bugs and glitches.

Picture doesn't look like invitation; not interested.

My ipad is not finding the update. I got Beta 4 the other day but it says up to date now. I even restarted it. Did the ipad not get Beta 5?

Haha, this is MacOS.:p
