Big Sur 11.0.1 RC2 Installation Issue

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:

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?

Same issue on MacBook Pro 16" 2019
Same issue here with my iMac (Retina 5K, 27-inch, 2020)
Okay ... I think it is clear now that this issue is present on multiple machines. Can we please stop the ongoing "same here"...
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:

Code Block bash
sudo nvram IASUCatalogURL=https://swscan.apple.com/content/catalogs/others/index-10.16seed-10.16-10.15-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog


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:
