Buying used mac mini 2018 I decided to do a clean system install to be sure that it is clean. I followed the steps from the Apple docs: https://support.apple.com/en-us/HT201065
- signed out of everything
- reset NVRAM
- erased disk
then I followed the reinstallation procedure:
Command-R failed with some 2008F error or something so after some reading and thinking I used
Option-Command-R which should install the latest OS available and compatible and that installs Bug Sur.
First it says I will have to wait for some 40 min for the process to finish and everything seems to go fine, but then around 11 mins before the end some problems start and the installation is cancelled with a human error saying:
An error occurred installing macOS. You can try again to complete the installation.
Of course I've tried not once not twice, always ends with the same message and in a similar way when checking the logs. And talking about logs I managed to copy them so if anyone can read something useful from them and recommend any action that could solve the issue - here they are: https://gist.github.com/piotrku/ae887b38ffcb25fad6810d3a7e4c5465
I'm using an Ethernet connection and the Internet connection is quite good (I event connected directly to the modem to bypass the router to be sure that no built in firewall causes the failure) and I tried on different hours for the past 3 days. I also read many pages describing similar problems but didn't found any real solutions.
Installing Bur Sur from USB fails (I think the same way as when installing from internet but fails). Installing Catalina from USB fails at the beginning with error 1008f. Doing
Shift-Option-Command-R fails with some error like 1008f or 2008f at the globe stage beginning the process.
I don't know if there are any options left than sending it to Apple repair :(
