MP All Models OpenCore Patcher Errors

[Macschrauber]

Hey, I don't know much about Macs but how do you find the volume of the USB disk, also how do you change the name of the install?

I made some tools around that topic, its part of the Dumper package:

Macschrauber-s-Rom-Dump/ESP_tools.md at main · Macschrauber/Macschrauber-s-Rom-Dump

A tool for dumping and analysing Mac firmwares. Plus flashing for Mac Pro 4.1 / 5.1 - Macschrauber/Macschrauber-s-Rom-Dump

Changing the name of the installer app is not important. All you need is the correct path to the createinstallmedia command. Don't type the full terminal command, as it is much too easy to mis-type the path and command, which results in very quick errors, then try re-typing again, with likely more frustration with the terminal, and the command line, particularly if you rarely use the terminal. MUCH easier (and helps avoid spelling errors, and mis-typing of critical commands)...
Try this! (You don't need to change any file names, or rename any volumes (except for the initial erase of the flash drive (or other USB volume that you want to use for an installer), The process will erase and rename that USB for you, but you do need to prepare that drive, so that can be any name to begin the process...

Make installer bootable on flash drive:
Insert your USB flash drive (use a 16GB flash drive for this). Erase that thumb drive, using your Disk Utility. Make sure it is formatted Mac OS Extended (journaled), and the partition Map is "GUID"

The macOS installer app (Install macOS "whatever") should be in your Applications folder, but another location will be OK for creating the bootable installer that you need.

Right click on that installer app, and choose "Show Package Contents". Open the “Contents” folder, then open the "Resources" folder. Leave that alone for a moment...

Launch your Terminal app, then, at the prompt, type sudo, and add a single space.

From the Resources folder that you left open, drag the file "createinstallmedia" and drop it on your terminal window. You will see the full path to that file appear next to sudo.

Next, type --volume, and add one space to that. (notice there are TWO dashes, not just one)

Now, find the icon for your flash drive (the one you just erased. Should be on your desktop somewhere). Drag that icon into the terminal window. You will see that disk, with its path, added to the line you have been typing.

AND, press enter. You will be asked to enter your admin password.

You will NOT see the password as you type (it's a security feature), just type your password, then press enter. It will work.
Finally, the terminal will ask you to press "y" to start the command that you just typed, so type y, and press enter.

Then, you will see some text appear, showing the progress of the command. Some flash drives will be slow, and can take 30 minutes for this task. It will get to 100%, then do a few final items to complete the installer and make it bootable. Finally, the last line will tell you the bootable installer is ready to use (or something like that)… And, it's ready to go! (and you typed only a few characters!)

I hope that helps you!

Hi, folks, I hope you can assist, or point me to another thread if appropriate. I have a flashed 2009 MP 5,1 that has an older open core install (approx) 2022 and has been running Monterey 12.4 perfectly all this time. I have a Radeon RX 580 8 GB GPU and 2 x 3.33 GHz 6-Core Intel Xeon processors.

Certain apps, including Safari of all things, are starting to have problems loading pages. So, I began to upgrade Open Core using the latest Dortania Patcher app. I (hope?) successfully created a USB installer for Sonoma and here's where I'm hitting a wall.

The next step is asking me to click "Reboot", hold down the Option key and then move forward with the process by selecting the EFI Boot entry. When I click Reboot and wait for the startup chime, I press and hold the Option key but the boot-up never moves any further. I have a black screen that never progresses. I've held the Option key down as long as 2 - 3 minutes. Am I being impatient and because this is coming from a USB drive, do I need to keep holding down the Option key?

Dumb question #1 - as I was building the installer, it asked me which disk to install OpenCore. I assumed I wanted it installed on the USB installer, right, and not the SSD drive that will be my boot drive? Assuming this is correct, then I have successfully installed Open Core on the USB drive.

If I don't hold down the Option key, and if I remove the existing SSD boot drive, the Mac will boot using the USB installer, and offer to install Sonoma. I had the installer put Sonoma on a brand-new, formatted Samsung 870 EVO SSD drive, but when I turned the computer off and tried to boot to that drive, nothing happened. I'm sure this is because I have not completed the "Booting Open Core and macOS steps". I can't get to the Boot Picker screen.

Dumb question #2: In my MP 2009 5, the existing Monterey SSD boot drive is in the slot closest to the back of the cabinet, where the cards, etc. are inserted. I tried to plug in the new, blank SSD drive in the next slot toward the front, but the system isn't recognizing the drive. Even though there are multiple slots for these drives, am I limited to a single slot? Specifically the one closest to the rear of the cabinet? Or, am I limited to only one SSD drive at a time, for some reason?

Summary: How do I get past the blank screen when I reboot after creating the installer, and what do I need to know about the SSD drives, slots, limitations, specific locations, etc.

Many Thanks!

Samsung 870 EVO is known to cause warm reboot problems, try again with a known compatible SSD. Some people have better success connecting the 870 EVO to the second optical drive bay, the ODD SATA connectors seems the only place that is more or less reliable for the 870 EVO in the MacPro5,1.

If you are connecting via SATA drive bays all are the same and all accept SSDs.
