Running Ventura on this MBP16,1 now.
Clean install on an external SSD in my usual way: CCC clone of the data volume to an erased SSD; install Ventura over it from USB installer (InstallAssistant.pkg obtained via gibMacOS). All straightforward as it should on a supported machine, still good to know that this 1st beta of Ventura behaves well.
Edit: booting back into Monterey (internal SSD) worked and running fine, but it did an extra reboot in the background - don't know what it did. Maybe should be more prudent with such an early beta, even if on an external disk.
Couldn't refrain from trying a Ventura installation also on my retired (partly repaired) MBP5,2 (Penryn 9600).
Using the same USB installer and OCLP 046n latest (from yesterday) from source, on the EFI of the external target SSD.
- to get the Ventura installer up, needed to plug in an external mouse (+keyboard) to USB. Reminded me of the early days of Big Sur when Legacy USB injector wasn't in place yet.
- after the first installation phase the 2nd wouldn't start but displayed "OCB: StartImage failed - aborted" in a boot loop. Powered off, disconnected the USB installer and then in OCLP picker did CMDS+S and could boot macOS Installer. Needed again external keyboard to "exit" from verbose prompt.
- the subsequent installation phases all proceeded well (without CMD+S). Installed system didn't boot, as expected from earlier messages on this thread and on Discord. Reason was a libSystem.B.dylib not found as (I think) also already reported. No obvious signs of invalid instructions.
But not too bad. Some Penryn success reported on Discord - looking forward to benefit from this tomorrow.
