I'm trying to update to beta 3 and am being presented with the following error:
An error occurred installing the update.
You can try again to complete the installation.

Has anyone been able to successfully update?

Update:
Looking through install.log, it seems that the BridgeOS version the updater its looking for is newer than what Beta 2 includes. This probably explains why only machines with the T1/T2 chips are having issues...

Update 2:
Apple pushed a new update. Machines with a T2 chip should have no problem installing the update (cmd+r the Software Update window to have it recheck for the new update).

No luck of yet. Tried restarting MacBook, shutting down, and recovery mode to force install beta again(gives an error that it can't download important files at this time). Seems their servers may be overloaded!

Try again this command in Terminal later again:

sudo softwareupdate --dump-state -i -a

Or in case your update is really really stuck:

1. Restart your mac, press Command + R, then enter into Recovery HD.
2. Choose utility menu, select Terminal.
3. csrutil disable to disable SIP.
4. reboot.
5. Delete the files in folder /Library/Updates.
6. Enter Recovery HD again, and input csrutil enable in Terminal.
7. reboot.
8. Check the update should work.

Haven't even tried on my 2012 MBP. I've heard so many people are having issues so I'm just going to avoid it now.

Can't delete the update in /Library/Updates as it tells me
