Running into an issue installing Big Sur on top of Catalina 10.15.7 on 2019 Mac Pro.

Downloads the installer no problem, but after a bit running - runs into a very generic dialog with 
Code Block 
An error occured installing macOS.
You can try again to complete the installation.



From the console, I can see that it tries to go through some networking, and everything is successful up until bridgeOS update download.

Relevant lines seem to be:

(formatted for readability)




A bit of google searching got me thinking that there seems to be something hay-wire with T2 firmware update, but before I go nuking it on my dev machine, I am curious whether anyone else ran into this, or what likely is the culprit, when should we expect the required components be fully upgraded so the installer can download them?

I'm getting the same thing. I uninstalled everything and then repeated the steps again with the Console application open and saw this during the "C-R" in the software update pane of system settings:

I'll chime in with a 'me too' from multiple Mac systems (all with a T2). I was trying to go from MacOS 10.15.7 (19H15) to 11.0.1 RC2 on some test systems before GA on Thursday.

Multiple forums have users with the exact same problem, so it's clearly something Apple needs to take care of. I'm certain they're aware. :-)

I did a quick analysis of the HTTP URLs present in my install error log. Of the 76 unique URLs listed, 11 of them gave a 404 response, meaning about 1 in 7 were not found. Example (edited for clarity) of one 404: http://swcdn.apple.com/content/downloads/06/41/***/***/MRTConfigData_10_15.pkg.

This could be unrelated and normal, or it could be that the a file required for the bridge update was not found, so it could not update, and the install failed.

Pure speculation, but a reasonable possibility. If so, apple could drop the missing bits in place on the CDN, and the installers would magically start to work, maybe?

I dug deeper, and if you look at the catalog the installer is using: https://swscan.apple.com/content/catalogs/others/index-11-10.15-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog

And search for "BridgeOSPredicateProductOrdering" you can see it only lists URLs for versions:

Code Block 
17.16.16610.0.0
17.16.14538.0.0
17.16.15580.0.0

You can see in the install logs where it is using this catalog to find the bridgeOS update:

It seems to me the sucatalog on Apples end needs to be updated to reflect the URL of version 18.16.12561.0.0. I found some other posts online that indicate a "revive" of T2 as per https://support.apple.com/en-gb/guide/apple-configurator-2/apdebea5be51/mac can resolve it, but I have yet to test this myself.

My install of the Beta (prior to RC 2) on Mac mini 2018 required the firmware update to be run. Update took a LOOONNNGG time, but did update the firmware during the Beta install. Currently reports this version:
  System Firmware Version: 1554.50.3.0.0 (iBridge: 18.16.12561.0.0,0)
My install was a clean install onto an external drive that was freshly erased before install.

So your log in particular looks like the firmware updated didn't run. Was the install onto an external drive? There were issues with firmware updaters years ago (before Sierra?) not running when the OS install target disk was not the internal drive.

@ts85 answer fixes the issue, but they made a typo. Enter this into the Terminal prior to running the installer:

Same here with a 16" 2019 MBP - definitely seems like a T2 issue and clearing caches and other measures has no effect, this has been an issue for me since 10.15.5 and I'm still running that version as a consequence.

Different issue as the one above, but still to do with the BridgeOS update :/

Had the same issue installing macOS 11.0.1 RC2 and @kmcbride comment allowed me to install.

bridgeOS is on the right version:
Code Block 
  System Firmware Version:	1554.50.3.0.0 (iBridge: 18.16.12561.0.0,0)


My previous error message:
Code Block 
Nov 11 10:05:22 osinstallersetupd[779]: bridgeOS update prepare failed: Error Domain=BOSErrorDomain Code=110 "The bridgeOS update doesn't satisfy the given minimum version requirement."
