Hi
I got a problem upgrading to Sonoma (but it's the same with Monterey, Ventura), during the installation, using oclp, at the 3° restart, the machine stacks. The imac works only with high sierra. someone can help me?
thank you in advance

Try to install sonoma in hdd partition
After that you do a back up / restoration in the ssd partition

In my limited experience with OCLP, upgrades on some Macs require careful attention. Make sure that on each reboot, hold the Option key, and make sure that you select the EFI partition on your drive, then make sure that OCLP is then using the corrent partition to finish the install. It will (usually) have the correct partition pre-selected, BUT always make sure that you manually choose that EFI partition as the first choice on each restart.

Can I ask you...? What do you mean by "the machine stacks"? Do you get an error pop-up of some kind? What exactly happens, or what do you see?

Ciao, sorry for the delay, well, I'm sure the efi partition is loaded by OCLP, I've added '-v' and it works...the machine stacks over here...
