MP 1,1-5,1 Help needed... can't install Ventura nor Sonoma on my 5,1

[oeyvind]

Hi there,

I'm trying to get Ventura or Sonoma installed on my 5,1... I can install Ventura and Sonoma after booting up from USB created via OCLP 1.3 however I'm kinda stuck in this screen after the 1st reboot where macOS update assistant trying to update some firmware to my SSD?

Don't think I ever encounter this before previously...

Thanks in advance!

You need to update your firmware to the latest version. See this thread https://forums.macrumors.com/threads/mac-pro-5-1-rom-question.2414663/

I advise against upgrading cMP to anything greater than Monterey, but if you need support with OCLP join their Discord.

Which version of OCLP are you using? I having problems and I'm wondering if it's 1.3.0 that causing the issue? I have already done this successfully once using 1.1.0

The OS managed to install so I guess its not OCLP's fault? However I'm stuck at that screen I showed upon the 1st reboot..

OCLP used was 1.3
