Apple Releases Sixth Beta of macOS Big Sur to Developers [Updated]

[MCKLMT]

It’s crashes immediately, no chanche to sign out.

I encounter the same issue. iMessage crashs each time I open it. Any idea how to solve this issue?

Edit: a reboot fixed the issue!

 

[ErikGrim]

Success!

Hey Siri and Watch unlock still doesn't work though

FWIW, my 2020 iMac updated perfectly fine as well. Download took forever though

Big Sur installers act more like the iOS installer now, it downloads then prepares before it runs the installer. So if you not watching what it does it would seem like the download is taking a very long time.

SMB shares are borked. Not even my windows VM can connect to them.

Same here.... just was reading the thread to see if others had experienced this also.

Other than that good thus far with limited time, but it did not load up my XS Max in finder despite seeing it. I wanted to synch and do a backup to the Mac after the iPhone was updated to the newest version of iOS 14, no dice. Going to try to link up to it from Music, but don't have much hope there and no need Xcode just yet to install.

so my Apple Watch unlock hasn’t been working for sometime...

just installed new beta and now I can’t even access Security and Privacy, it errors with this message before you make any changes.

Weirdly Apple Watch unlock never worked on my 2018 mini even after clean installs. On Big Sur it works perfectly every time.

SMB definitely broken in Beta 6 (doesn't matter if upgraded from Beta 5 or if I did a clean install). at least NFS works again since Beta 5 (it is still broken in Catalina 10.15.6 and was broken in Big Sur Beta 1-4).

 

[Mike Haas]

Not falling for it. Troll.

I hate to tell you this but it downloaded a bit slow, 57 minutes, several more minutes to prepare (like iPhone updates), then it took about 20 minutes to install on my 2019 13" MBP. I have never had the installation issues others report on either my 2017 13" MBP or my "new" 2019. I have had downloads fail - plenty of times, but no installation issues. I've been lucky, I guess. Even when I tell myself I won't, I get on the Beta Train every Summer and have been doing that for almost 15 bloody years. Catalina was never awesome like Mojave was, but I'm really liking Big Sur.

I've had one major issue that has dogged me, however: Occasionally, after rebooting from an update, my external drives are gone and it almost always takes switching the Thunderbolt-3 port because the one that was in use before absolutely refuses to recognize the USB hub.

SMB is broken here too... No connection to my qnap nas or my dd-wrt nas :-/

 

[Azrael9]

How is it compared to Catalina. Overall.

Speed? Performance?

Forwards step?

Backwards step?

Much the same?

Skip that step then

Just tried the first command, got a 'No updates are available' message within Terminal.

Funnily enough, around 20 seconds later, the update showed up in my Software Update panel in System Preferences (2020 iMac).

Probably just coincidence.

Where's the Command Line Tools for Xcode 12 beta 6?

 

[aevan]

I haven’t used any of the Big Sur betas yet. Just from reading other posts here, I kept hearing about bugs and instability. The iOS 14 betas have a good track record of being pretty stable, but I haven’t heard the same for the Big Sur betas.

I guess it depends on personal cases and different apps, but for me, the Big Sur betas were very stable to the point I forgot they were betas. But, again, this is just my experience - for some people it will be the other way around. Heh, that even happens with final versions

 

[Chris The Bipolarbear]

Anyone downloading Full Installer to check you have the right one, Right click get info make sure it is version 16.0.18. see screen shot beta 6 is on Left

 

[PBG4 Dude]

I'm not seeing anyone having success with this on a 2020 iMac.

I have it running on my 2020 iMac using an external SSD.

 

[Rob F]

SMB working for me - but only when connecting to SMB3 volumes

So...how did it go on your 2020 iMac? That is what I was talking about. That is all I was talking about? This is the first beta that is supposed to work on that particular model.

Adobe always seems to be behind in new OS support. Fortunately I can use it in my Windows VM with no issue.

I never had problems with any Adobe app, or Message for that matter, since the first beta🤔

So you can use Acrobat Pro to edit and modify pdf files?

 

[bananajoe81]

HI, these 2 commands in the terminal have fixed my SMB problem with the beta 6:

Open Terminal and type:

sudo sh -c 'echo "[default]\nsigning_required=no" > /etc/nsmb.conf'

defaults write com.apple.desktopservices DSDontWriteNetworkStores true

Quit terminal

I've been using MacOS Betas continuously since they first came out and have always had good luck, but Big Sur Public Beta 2 (Beta 5) was a mess. It's the first time I ever reverted from a MacOS beta. Not as bad as the first Big Sur Public Beta which was simply unstable and crashed often, but way too many apps not working that are evidently now working in Beta 6 and hence were Apple bugs, not the app developers being behind the curve. So I'll wait a while and probably adopt Big Sur Public Beta 3, but it's been very disappointing this time around.

I can confirm that I've been having the same issues as you with Adobe Acrobat when trying to edit/modify PDF files. Full-blown crash.

Still no keyboard shortcut to delete messages conversations. This is really frustrating.

Remember that you can make your own in Keyboard/Shortcuts/App Shortcuts

Wow, for me, the worst Big Sur beta ever! Impossible to add my own photos on System Preferences (SP freezes completely and then, freezes the whole system). For some reason the downloads on Transmission breaks from time to time showing the following message: "error: unable to save resume file: No such file or directory". Horrid. I strongly recommend not to update to beta 6.
