Hi Folks... have been struggling to figure this out on my own for over a week, obviously not getting anywhere. Any help is appreciated!
I have a MP 5,1 with 32GB RAM and Sapphire RX580. I am using a wired keyboard and mouse. Until recently, I have been successfully using it for years with BigSur. I also have a MacBookPro11,1 which is a 2013 A1502 MacBook Pro 2.4 GHz Intel Core i5 with 16GB RAM running High Sierra 10.13.6
So, I've been trying (unsuccessfully) to upgrade my cMP to Sonoma by doing a fresh install into a blank SSD. I downloaded OCLP 2.2.0 and followed the process to create a USB boot disk. However, when doing the install, I made a mistake and installed it into my EFI folder on my cMP. Now the cMP won't boot up at all. In addition, I tried to hold down Option to get to the USB boot disk again, but that wouldn't come up either.
Next, thinking I didn't create the USB boot disk properly, I created a new one using my MBP11,1. I've made sure to select the Mac Pro 5,1 in the settings of Open Core. Created an Installer for Sonoma on to the USB. Held down Option during startup and I was able to get a menu to select one of three options: the blank SSD onto which I wanted to install Sonoma. InstallSonoma selection. And an EFI selection... not "EFI Boot". Clicking on EFI doesn't do anything except the same boot menu of the SSD, InstallSonoma, and EFI comes up each time. Clicking on InstallSonoma gets me to selecting the English language for Sonoma, but it's looking for a bluetooth keyboard and mouse, and all i have is a wired keyboard and mouse instead.
- I've tried to create this USB boot disk mulitple times via my MBP but it won't create an EFI Boot, only EFI folder.
- Trying to boot up the cMP will make it just sit there until I power it down. Or, if I hold down Option while booting, it will go to the same three menus on the USB drive, but again no EFI Boot/OC folder and InstallSonoma doesn't get me anywhere.
- Tried to reset the PRAM/NVRAM via holding down Option+Command+P+R keys for at least two boot-up Bong chimes. But ater a fwe minutes, the cMP just goes into a loop of making the boot-up Bong sound, waiting a few minutes and making the same Bong sound again.
- Tried to boot into Recovery Mode via Command+R, but it won't go into it and just sits there.
I don't know what I am doing wrong... did I just kill the boot sector on my cMP completely such that I can't even boot from the USB anymore? I've thought that maybe I am doing something wrong with creating the USB boot drive because I all I keep seeing is the EFI folder and not EFI Boot; but I have gone through this so many times now and tried to follow the process specifically each time.
Any thoughts or suggestions? I've been doing this for over a week now and I'm just spent!
Thanks, in advanced.
