Hey. I'm new to the subject and need your help.
I have MB 12' 2017 16RAM on hand and want to upgrade to Sonoma. I created a download flash drive according to the instructions on the Internet and further steps:
Booted into recovery mode
Created a new partition on the drive to install OS 2 (save the old one and for the new Sonoma)
In recovery mode, clicked on Sonoma installation, selected a new section for the new OS
Next, the OS installation began, but after about 20 minutes of waiting, the laptop turned off
Next, loading from Option into download select mode - selecting EFI -> Install Sonoma
And then the laptop shows a wait of 30 minutes. When it gets to 20, it turns off and repeats everything again. I tried to do the clean installation in the same way - the picture is the same. Please help
