Macbook 12‘‘ early 2015 Opencore fails to install OS

Hey guys,

I have been trying to upgrade my Macbook from Big sur to Sequoia and Sonoma via the OCLP, but everytime i reeboot the System to install the new Os off the bootstick to my SSD the Macbook suddenly shuts down at about 3/4 of the installation process. Then it turns on again an sets me back to the boot menu. I dont get any errors or so it just shuts down whilst installing.

I already tried different usb sticks, reinstalling everything and start from zero again but nothing works.

The ssd of the Macbook is completely empty so space should not be the problem.

Anyone who hat this problem?

Peter
