I started my investigation by checking the EC2 instances: [REDRACTED] & [REDACTED], and could gather that the instances were launched from AMIs: macOS Ventura 13.2.1 and macOS Monterey 12.6.3 respectively. As you are already aware that Apple has recently published an update to MacOS & bridgeOS(IPSW 20P4252 or 20.16.4252.0.0 ), which is used to verify which MacOS version is supported on our Mac1.metal dedicated hosts. The macOS Ventura v13.xx series needs this latest bridgeOS version to successfully boot up. On checking internally, I was able to find that your host: [REDRACTED] has BridgeOS version: 19.16.10744.0.0,0 . As you can see that the underlying hardware is running an older BridgeOS version of '19.16.10744.0.0,0', it can perhaps only boot up the following macOS versions, everything else apart from this will continue to fail. • macOS 11.6.3 • macOS 11.6.4 • macOS 12.2 • macOS 12.2.1

Broken AWS macOS servers alert :woozy_aws: Many Intel Mac bare-metal servers (mac1.metal) are broken due to old incompatible firmware (AWS has a custom management system but firmware upgrade is broken right now). Apple Silicon Macs (mac2.metal) seem to work well. On Intel, use these supported versions only.

This firmware problem has existed a month or more, but is still completely undocumented to my best knowledge. It's a Gacha game right now: "pay $20 to allocate a server that can run macOS 13, for at least 24 hours (macOS EULA, thanks Apple!). If it doesn't work, pay $20 again and try another one..." I'm now trying to get refunded.
