I am struggling to install macOS Sequoia on an 2019 Intel MBP. I erased the internal SSD with Disk Utility and formatted with APFS. First aid says everything is fine. But when I am trying to install macOS Sequoia via Internet Recovery it always stops at 14 minutes remaining during unarchiving with a failing hash check for /Volumes/Macintosh HD/macOS Install Data/UpdateBundle/AssetData/./payloadv2/payload.003 (see attached screenshot of the install log). The error displayed in the UI is “An error occurred loading the update”. An interesting observation is that the hash of that file is different on every installation attempt.
I verified that my internet connection can’t be the problem: I installed via a wired connection and was able to successfully upgrade an M1 MBP over the very same connection. Also the internal SSD can’t be the problem, because when I am trying to install on an external drive the same error occurs (no problem to install on the external drive with the M1 MBP).
Has anyone experienced similar issues and could resolve them?
Thanks in advance for your suggestions.
