MB 1,1-7,1 Sonoma installer won’t boot without 🚫

[DominikHoffmann]

I got my MacBook5,1 (equipped with 8 GB of RAM and a 1 TB SATA SSD) to the point, where it is running macOS High Sierra (thanks to DosDude1!). I downloaded OpenCore Legacy Patcher (OCLP) 1.5.0, copied the most recent Sonoma installer app to /Applications/, used OCLP to make a USB flash drive installer from that and installed the root patches on it. It now has OCLP on the EFI Boot partition.

When I boot into the USB flash drive’s EFI Boot partition and then continue booting from the Sonoma installer partition, I get the prohibited symbol (🚫):

I looked at “Stuck on This version of Mac OS X is not supported on this platform or (🚫) Prohibited Symbol” in the Troubleshooting section on the OCLP web pages, but it does not offer a solution other than trying to recreate the USB flash drive with a different physical drive. This already is the second flash drive that exhibits this behavior.

I made a Ventura installer flash drive and was able to install Ventura on the system successfully.

To further troubleshoot, I can try verbose booting to see, where it gets stuck, when trying to boot into a Sonoma installer. Will the verbose boot-up selection survive past the EFI bootloader?

Dear Dominik Hoffmann, I have the exact same problem. Did you found the cause of it?

As it turns out—and I thought I had reported this back here—in verbose mode the problem does not occur. What I ended up doing, however, was enable verbose booting several times during the install process, because it involves several reboots. When you notice a stalled install, just force a reboot and immediately hold down ⌘-V. Eventually, you will get there—at least I did.

I will refrain from trying to upgrade this one to Sequoia, however.

Thank you very much, it worked! But at some point I stuck and it wouldn't boot farther even in verbose mode, so I had to plug in the usb driver through usb 2.0 hub and disable SIT (I will put the link on how to do it down below for others who is also stuck there)
My best guess it that the whole problem was because we didn't disable SIT)

Well, that’s certainly a very valuable discovery! Thank you very much for sharing that!

I can also report that the MacBook has some issues. For example, the Music app, my son says, crashes, whenever he searches the Apple Music catalog.
