What happened here?

I literally was just telling a friend how DP5 was the cleanest DP I've ever seen from Apple in the last 10 years I've been using betas. Then the next day DP6 drops, and I installed it.... now...

- Have gotten 3 BSODs in the last 48 hours, more than I've seen in 10 years.
- rMBP has rebooted without warning 2-3 times in 48 hours.
- Tons of screen glitches
- Safari odd lag when opening a new page via click to open new window load
- Random issues like when pressing and holding power computer just shuts off doesn't present options

I should have kept my mouth shut and not bragged about how clean DP5 was... but it just baffles me as to how Apple can regress backwards with more bugs as newer versions come out. Very odd!
 
not everyone is having the same experience. i had some of those issues (the first 3, plus email issues, some other quirks) UNTIL the current beta (for me, PB5). odd though, that what's fixed for me is now an issue for you. what the..???

Yep, you're a version behind. When I was on the last version everything was buttery smooth and amazing.. hopefully they skip the version I'm on in the next PB for your sake :)

The same things happened when I updated from PB4 to PB5
 
Oddly, I'm finding DP6 to be more stable than DP5 though I'm running it (and replying to this) on my 2015 MacBook 12". General usage, the battery life and overall responsiveness seems much improved compared to the last one. I used to get quite a few Safari crashes (particularly on sites like Ars Technica) but they seem much reduced, as does the incidence of beachballs etc.

I've got a late 2013 15" MBP and I haven't had much luck with any of the Sierra DPs on it. I recently removed it from its test partition, mainly due to the instability it introduced when booting El Capitan. I can't remember whether it was DP4 or DP5 but I got to the point where it got distracting so I thought I'd wait for the general release before trying again.
 
"Individual results may vary". How well any given beta works for you is entirely on the basis of what the environment that you're installing onto is like. If it was a clean install (reformatted drive), chances are the performance wouldn't be an issue. There's actually some levels of testing and validation done internally before these are released you know. :)

Then we complicate things by upgrading over several iterations of betas, with a number of applications and performance "tweaks" that we've done ourselves and we run into anomalies.

To be expected...

(people that get stressed out with software glitches likely shouldn't be running pre-release operating systems) :)

I agree with you but only in part. A beta working is definitely not reliant on a clean install. The purpose of a bets for the DP is for developers to test on in a real world environment. The PB are for the public to try and report bugs as an end user before the final release. Both are designed to simulate real world use. Nobody in their right mind does a clean install going from one OS X to the next.

When an OS comes out, it pops up and says "Sierra is out, download and install?" an the user clicks yes. In no circumstance has the norm EVER been to start fresh with a clean install. THAT is not reality and that's not the way the process works. I'd bet 99.99% of users just click install and are done with it.

So to suggest that someone needs to do a clean install to avoid dealing with bugs and issues is like saying when you need an oil change in your car you've got to have the engine taken out and rebuilt to maintain performance. Absolutely false. It's not installing an os on top of an os on top of an OS, it's rewriting the code for the aspects being replaced.

That's the plight of being in the beta program unfortunately. One build, it looks like you're nearly at the gold release, the next, could be a huge step back

I'm keeping my fingers crossed it goes back to the quality of DP5. Funny I bragged about how clean and smooth DP5 was for a beta to my friend who works for Apple... and then DP6 rolled out the next day and I ate my words, lol

Yeah and it was working great before. It's really weird... I question how apple compiles their beta versions when previous bugs come back.

There's a big difference between the expectations of GA releases and beta releases. Yes, both types of installs need to be tested as part of the beta program. Jumping to the conclusion that Apple has released a steaming pile of 5#!7 because it doesn't run well on YOUR particular setup, however, is to ignore the environment characteristics that are causing those anomalies. (this is what bug reporting is for - have you documented and reported these?)

As to doing a clean install. If you installed this over your El Capitan and plan on installing the GA overtop the multiple beta installations, then that is truly foolish as elements may be eliminated before GA, causing your configuration to experience many anomalies that could be tiresome indeed to try to isolate.
 
Yes, but that's not why I offered the link.

As well as Problem Reporter, did you use Feedback Assistant and attach a .panic file?

You mentioned oddness, and being baffled. Can you share the content of three or more of the .panic files?

If you expect a panic to recur

This routine should help diagnosis:
  1. Start Recovery OS
  2. in Terminal, enter the command below
  3. restart (macOS).
nvram boot-args="-v keepsyms=y"

Subsequent .panic files will include more human-friendly information.

When you no longer require that level of information, you can reset NVRAM.
